Title: New ZyXEL VMG8924-B10A Installed
Post by: broadstairs on February 15, 2015, 11:48:22 AM
I managed to pick up a pretty much new VMG8924-B10A off eBay this week at a reasonable price and have just installed it currently in series with my HG612, if all goes well I might try it on its own in a week or so. I decided to flash it with the latest firmware showing as 1.00(AAKL.7) on the status screen. I have had no issues with it during setup so will see how it behaves. I decided to go for this because I like the 5G wi-fi which seems better round the house and all but one device I have is 5G capable, I also like the ability to turn off the LEDs on a timer since it has to be situated in a bedroom (master socket in in storage space behind bed!).

Since I installed this router I have been having quite a lot of problems with CRCs and ESs on my line but I did not think that changing the outer behind the HG612 would make that sort of difference. How likely is it that my new VMG8924-B10A is causing the problems or is it far more likely that I have some real noise issues on my line and it just happens to be co-incidental that it started around the same time. The problems dont happen all day and can vary the time of day so it is not continuous.

Maybe Try 1.00(AAKL.6)b1  ?

Kitz noted the 6b1 has been stable.


FWIW. I'm using Current Firmware Version: 1.00(AAKL.6)b1

I did have a brief stint with 6b2 (iirc) which was when they changed the max telnet sessions and I had a couple of lock ups because I use both dslstats and hg612 modem stats.  I rolled back to 6b1 and since then Ive been continually up without any problems.

   The Zyxel proved very bad for CRC and ES on my line but others have had no or smaller issues.  I had 3 times more ES than a HG612.   A swap back to an HG612 should let you decide whether it is the Zyxel. 


   Edit.  This comment is for a Zyxel on its own, if it behind a HG612 it should not have any impact on errors at all.

Did find the 63168 can be a little more sensitive than the 6368 38(k)onwards for some reason.

Was certainly noticable with our cisco units.

in addition eric seemed to have issues after switching from a billion 8800nl to the zyxel, on my line the zyxel has the worst error rate out of the 3.

I have been having quite a lot of problems with CRCs and ESs on my line but I did not think that changing the outer behind the HG612 would make that sort of difference.

How can a router behind the HG612 cause the HG612 to report more CRCs and E/S?   It's still the HG612 that is performing handling of the line because that's what contains the modem.   The only possible thing I can think of is that the PSU is faulty and generating noise, but even then you'd expect it to be continuous and not spikey.


------------

I may sound defensive of the Zyxel, and I appreciate that it didnt perform as well on les's line... and a handful of users such as chrys did see slighly more errors and eric saw more, but his line was performing oddly anyhow prior to that.

The fact is that the Zyxel does perform better on many lines, even noisy ones such as Ronski's..  and on my own line it performs much better than the HG612.   

I fully appreciate that there are differences between the 6368 and 63168 based routers, but that does appear to be down to the chipset.   As I keep saying it all depends on the type of noise your line experiences and we still dont know how g.inp fits in there.   At the end of the day it's always been that some chipsets  work better on some lines than on others and I still feel that the BCMs be they 6368 or 63168 perform better than some of the other chipsets.     Even then you get the odd line thrown into the mix that may perform better on a lantiq.     I dont diss lantiqs which perform quite poorly on my line, nor do I diss the HG612 which cant sync at 80/20 when the Zyxel performs happily and rock steady with some to spare.  The vast majority of people with Zyxels seem to see better results.   I'm not paid by anyone to say that..  I just use the Zyxel pure and simple because it works far the best on my line.

I think we just have to accept that its a case of suck it and see as to which performs best for you.


/off to bed as Im very tired and when Im as tired as I am... I tend to get ratty. g'nite. :)

Thanks Kitz for confirming what I thought but it's nice to know I'm correct. I could change the PSU for the VMG8324 one I guess as they may well be the same. I'll also dig out my radio scanner and see if I can hear anything, the landline seems OK (ie no noise). I was a bit miffed that some folks did not spot what I said about the HG612 still being in place though.

Post by: les-70 on February 22, 2015, 08:37:53 AM
  You should not be miffed about folk not spotting The Xyxel was behind the HG612.  Your initial post says that you would try the Xyxel on its in weeks time and the second post nearly a week later did not repeat that HG612 was in front.  I read your posts carefully but simply, as the Xyxel behind the HG612 should not make any difference, I assumed you had changed to having it on its own.  I also commented that if you had not got it on its own, it should make no difference.

  I am sure others assumed the same. The I think the PSU is normal 12v one and should be swap-able with another.  If that makes no difference you could try try the Xyxel on its own, it may work well for you.

Still running with the HG612 and today so far my noise has gone away, the past days when it happened my ES per hour had gone through the roof by between 7 and 8 AM calming down around 5 to 6 PM, overnight it went back to more usual levels. I have not swapped the PSU for the ZyXEL as I dont believe it is the problem as it all seems OK now. The errors causing the ES increase was almost exclusively CRCs which could get into the high hundreds a minute! There did not seem to be anything new around outside to cause the issue, no new neighbours or new things springing up so its all a tad strange.

Can anyone give me any pointers?

Strange but my increasin CRCs have returned again this weekend with it peaking at around 800/minute in the past hour and my ES rising as a consequence. Be interesting to see if this all goes away by Monday again. I have no idea why as noting in the locality seems to have changed, only thing is it is wet and windy again!

I have a problem with my ZyXEL VMG8924 B10A:using together 2.4Ghz (Dell Precision M4700) and 5Ghz (Samsung Galaxy Note 3) the router after few minutes reboots.

It doesn't happen using only 5 Ghz only, or 5 Ghz and a pc connected to the switch.

No explanation from Italian tech support.....

I have both 2.4ghz and 5ghz enabled, most of my devices use 5ghz but a couple of printers and one tablet are 2.4ghz. So far I have had no reboots of the router at all for any reason since installing it. What firmware version is your router using? Mine is using the latest available.

Got exactly the same with my Billion 8800NL using the firmware with version 39 DSL driver. Going back to the 38 driver cured the problems. Maybe try an older firmware with the older driver?

Should have said that the Zyxel is still not doing the DSL part, still using my HG612. I may try the ZyXEL native soon but have not done so yet.

Hi

Just got one of these on order so looking around doing my research after purchase  ::)

I would try the Zyxel directly on the line and see if that cures the CRC errors.  It might be some constructive interference between the two boxes, are they fairly close in proximity?  It could be you always had these phases of noise on the line and with an extra bit of noise thrown in by the Zyxel it now shows up as CRC errors, or could just be a coincidence.

I'm replacing an HG612 and a Billion 7800DX to get a one box solution and AC Wi-FI, and this one ticked the boxes with the option of VoIP as well.  I think Billion were looking to bring out something similar to the Zyxel but news seems to be they've dropped plans to.  The Zyxel VMG8924 is certainly comprehensive with all the settings and features available, will be nice to have alerts emailed (the Billion takes email server settings but never emails anything proactively), plus hopefully a firewall that works.  The Billion firewall doesn't do anything when you port forward as that takes priority, so to restrict access to a port forward it's a case of needing to block outgoing traffic!

Should have it in a couple of days hopefully.  Seen Kitz setup instructions so will follow those.

Regards

Phil

Cheers for the tip, I had read your post elsewhere so it was already in my head to try 1 if 2 didn't work, currently on the Billion the setting is -1 which means untagged according to the interface.  I'm with Xilo, not sure that makes a difference, so hopefully 1 or 2 will work.

Yes they are quite close, only a matter of inches actually. I might try moving the HG612 a bit further away, however the error bursts when they happen are quite extreme and I would have thought that if they were interfering with each other then the problem would be relatively constant. If moving the HG612 makes no discernible difference then I will try the 8924 directly on the line later.

Hi

Just received this router this morning, coming from a Billion 7800DX.

Not had chance to set it up yet apart from plug in and connect from a tablet, but initial impressions are positive.  It is a fairly nondescript black plastic box with a "piano" finished front, it doesn't offend though, certainly for me it's much more attractive than the white vertical style that Billion seem to have switched to which was my other option for an all in one box.  I guess a lot depends on decor to which blends in more.

The indicators on the front are very smart, coming from the Billion where one LED flashed they all lit up to some degree because of the way the light guide worked, plus you could see them all through the vents lending an air of cheapness, and you didn't know what the LEDs were signalling without getting close to read the labeling underneath, the ZyXEL is much better designed in this regard.  The vertical standing should help with cooling, although the 7800DX didn't get particularly hot as it was mostly vents.  You can even turn the LEDs off or schedule them off, now that's a good design thought.

The Web UI looks more sophisticated, much more graphical than the Billion UI which always looked very dated to me.  It certainly offers a lot more features, I'm sure 90% of them I'll never use or change.

Nexus 9 connected at over 800Mbits/sec on AC on 5GHz in same room.

I'll set it up later and report back.

I moved the HG612 today a bit further away from the ZyXEL but it has not made any difference to the CRC spikes as I had one of about 300/min a short while ago. I will try removing the HG612 in a day or so to see how the ZyXEL stands up on its own.

I did have an issue with 2.4ghz wi-fi yesterday where one of my printers refused to connect until I re-booted the ZyXEL manually. I only have 2 printers and one tablet which use 2.4ghz and then not often but I have had no reboots of the router which have not been instigated by me.

Hi

Up and running okay, still connected to the HG612 via the WAN port just in case I needed to reboot the router while configuring, and so didn't want the DLM to throw one.

For info, anyone on Xilo, then VLAN settings don't apply, so untick the Active VLAN box.  On the Billion the 802.1P and 802.1q were set as -1, which is no setting.

Hi

Well after configuring the ZyXEL with nothing too complex, a port forward, a static entry in DHCP, turned on logging and added a schedule for Wi-Fi, it suddenly stopped working.

Lights are on, no one at home.  It stopped dishing out IP addresses (seemed to be working fine up to this) and I can't access the admin interface on either wired or Wi-Fi (well Wi-Fi will not connect given no IP addresses are given out).

The lights on the box, show Power on, no WAN connection now to the Internet, the network light for the WAN port is on, the light for LAN wired connections is on (occasional flicker), the 2.4G Wi-Fi light is on, and the 5G Wi-Fi light is on but dimmed.  It seems to go through the boot sequence then stop at this, I'm thinking a corrupt configuration, so next step when I have chance is to try and reset it then reconfigure.  This is on the latest firmware (7).

Any advice gratefully received.

Regards

Phil

If you want to investigate what is going on and have NOT powered the Zyxel off, there is the 4-pin header on the motherboard.

Connect a USB to RS232/TTL PL2303HX Cable Adapter COM Module Converter Adapter for Arduino to the header and you have an always open serial connection.
I bought this off ebay UK Here (http://www.ebay.co.uk/itm/350900210088?ru=http%3A%2F%2Fwww.ebay.co.uk%2Fsch%2Fi.html%3F_sacat%3D0%26_udlo%3D%26_udhi%3D%26_ftrt%3D901%26_ftrv%3D1%26_sabdlo%3D%26_sabdhi%3D%26_samilow%3D%26_samihi%3D%26_sadis%3D15%26_stpos%3D%26_sop%3D12%26_dmd%3D1%26_ipg%3D50%26_nkw%3D350900210088%26_rdc%3D1)

For connection Instructions and much more see dmcdonnell's Excellent thread 'Unbranding the ZyXel VMG8324-B10A' :
http://forum.kitz.co.uk/index.php/topic,13939.msg269724.html#msg269724 (http://forum.kitz.co.uk/index.php/topic,13939.msg269724.html#msg269724)

It was intended to allow the Eircom F1000 to be converted to an unlocked Zyxel vmg8324-B10a.
I used it to update the bootloader to allow zyxel firmware to be installed from the GUI
Additionally I can now capture all output when the router is running.
[Various process/scripts spit out messages which are not logged anywhere you can easiliy access. With no terminal connected the messages are lost.]
You will also need on windows 'ExtraPutty.exe' [search google to get] to setup a serial terminal @ 115200/8/1/None with DTR/RTS enabled.

You can connect the header cable and route it through one of the screw holes to make it all neat. [See Pic]
I can get access to the router by multiple means and catch all error messages etc.

Hi

Thanks for that tip.  I already have a RS232/TTL to USB board I use for microprocessor programming.  I'm a little reluctant of course to play around too much in case it is broken (i.e. more than software problem) and so I need to send it back, but might be tempted later once I know it is okay hardware wise.

What is the best method to update the firmware?  I used the Web UI interface and the Bin file, then did a reset to defaults just in case.  I noticed they bundle an EXE app to update the firmware, I'm wondering if that does more than via the Web UI (perhaps updating a boot loader via the EXE that doesn't happen via the Web UI), also they include a default Config file (.rom), should I have uploaded that after updating the firmware?

I cannot answer as I got my Zyxel (Eircom F1000) 2nd hand from dmcdonnell (No software included/needed)

If it is not too much trouble I would be grateful to get a copy of the files (*.exe & *.rom).
I would be able to investigate what the difference is.

The Web UI interface and the Bin file, then a reset to defaults is the way I have updated.

Remember to search kitz for the Thread about firmware for the Zyxel.

Hi

I've now reset the ZyXEL using the reset button on the back and it is now booting normally again, and I've added my configuration back so will put it on line again shortly.  Fingers crossed it was just a one off problem where I was in and out of the Web GUI. 

Anyone using the QoS or disabling it?

Surely that is because there is an HG612 "in front" of the ZyXEL and the latter is not operating as a modem+router?  :-\

If the ZyXEL is used in a "one box" set up, the standard Openreach VLANs will need to configured. Every VDSL2 service, regardless of CP/ISP (and Xilo is no exception), needs to have a modem with the correct tagged VLAN configured.

Hi

Found the problem, managed to re-create why it locks up and then needs resetting.  It is emailing the Event Logs.  I had done that previously and set up the option to send an email when the log was full, but didn't set that up again after the reset, and sure enough it was all still up and running this morning.

Just now I set up an SMTP server, set that up in the Log options, then clicked the manual option to 'Email the log now'.  The Web UI froze with the rotating wait graphic, I could then no longer log in to the Web UI or Telnet.  Internet was still up and working at this point although it seemed slower.  Eventually I had no option but to turn off and on again, it booted back up to the same state as before, unresponsive, so I need another reset.

I wonder if the problem is I'm using an internal IP address for the SMTP server which it doesn't like and gets stuck never timing out, eventually causing some corruption.  Who can I report this to?

Regards

Phil

Hi

Thanks, will contact them. 

I'm not exactly finding the VMG8924 very stable, it seems it doesn't take much poking around in the Web UI to cause the box to reboot.  Apart from the Email log issue which corrupts the entire box needing a hard reset, I've had two crashes while in the UI, one was the network overview where you can click an icon of a connected device and click more information, and the other was in the Traffic Status screen, the Web UI went to refresh the NAT stats, came back with nothing, then wouldn't let me log out, (just showed an empty dialogue), and a few seconds later the Internet radio stopped playing and it rebooted.

I expect they have some watchdog running on the Web UI code, so if the Web UI stops responding, it triggers a reboot.

Seems okay if I leave it alone and touch nothing.  Thankfully I'm still not using it as a modem, so it hasn't caused any DLM issues.

It's a bit disappointing so far, the hardware is good, being a fairly well put together Broadcom bit of kit, a shame about the software.

Edit, and another reboot, I only logged in to see what the traffic screen was called.  I've now disabled the Logging in case it is related and using up too much memory with logged items, pushing it over the edge when the Web UI is loaded.

Edit: Not the event log, just rebooted again on the NAT traffic status page.  :no:

Phil

What version firmware are you running ?

I have had a few quirks but never to the level of unstability or 'hanging' the router.

The latest version is V1.00(AAKL.7)C0 but most people seem to think that the earlier version V1.00(AAKL6)b1 is most stable.

Hi

Using the latest firmware (7).  It seems to be stable providing not much happens in the UI, for example it's been up 9 hours now overnight, but rebooted before then as I went into the UI and set a static DNS server under Home Networking.  I went to save the changes and it is just the wait icon spinning, and after several seconds I can guess what it is doing, rebooting.  Once it was back up I could see the changes hadn't saved, so made the exact same change and it saved fine.

So my dilemma now is do I have faulty one and so I should get it exchanged or is it just a software problem?  Given the reboots all happen when I'm in the Web UI seems to suggest software (it's not very well designed looking at the HTML which is using very old versions of jQuery and lots of JavaScript so it would not surprise me if the Web UI is the cause), and I've seen in their release notes they've needed to fix crashes, including one where the whole thing locked up needing a hard reset, which is the same issue I've seen with emailing, a corrupt config.  When not using the Web UI, then essentially it is just ticking along on Broadcom's supplied software stack and so no surprise it appears to be stable.

I'll see it how goes today, perhaps step back to an older version of the firmware.

Regards

Phil

Hi

So after around 11 hours up time I went into the Web GUI only to check the status page to check the uptime, so moved right from the graphical connection of devices, get the usual wait icon, it then never progressed to the status page, but stayed on the graphical page with the black dialogue saying "A problem no internet connection", yet the Internet was fine for about 2 minutes after that, the Web UI could not be logged back into, and of course after several minutes it rebooted, which is likely the action of a watchdog timer.

This can't be right can it, I'm now wondering if the problem is due to moving the Web GUI to port 8080.

Regards

Phil

Phil I cant help wondering if your box itself is defective. I have had mine running now for a month and have not had any of these issues. True I dont use the GUI every day but I do use it and have not had any issues with mine at all (touch wood  ;) ).

Stuart

Just had a thought, mine is running behind an HG612 using its WAN port. I have not tried running it on its own yet. I just wonder if that could be anything to do with the issue. How many other 8924 users run it as the only device?

Hi

Yes beginning to wonder if it is defective, perhaps a memory issue.  I had a router once that wouldn't save any of its configuration settings, worked fine, but as soon as it was rebooted everything was lost.

I've changed the admin port back to port 80, I had changed it to 8080 because I'd opened port 80 to the outside world.  The router does state the Web UI would be changed to port 8080 on adding a port forward for 80, only it never change (another bug), hence I did it manually.  However as I've not opened the Web UI to the WAN, it doesn't need to be 8080 internally, and I thought perhaps the box might be crashing on parsing the Url as they never tested it with seeing :8080 in the Request  Url.

I'm not running the box as a single box solution yet, just as well given the number of times it has crashed, so it is running behind a HG612.

Edit:  After changing the port back to port 80, and visiting a few pages in the Web GUI, it rebooted again!  Going to send it back.

Phil

Hi

Seems to be getting worse, it's been 6 hours of up time, and I haven't logged into the UI during that time, but just logged in to get myself a config backup to use on the new one, and arrived on the Web UI home page, and it immediately crashed and rebooted before I had chance to do anything.  This one has to be faulty.

It pattern is emerging where after a reboot it is fairly stable for a few hours at most, then after that it is pretty likely doing anything in the Web UI will reboot it.

I'll update everyone on Monday on how the replacement goes.

Sounds like my VMG8924-B10 behaved while using the under powered power supply. In my case it was often after I'd used telnet to access the stats.
The log showed the reboot was due to a "shared memory issue", can't remember the actual wording but will dig it out if required.

Error message was "Out of MDM shared memory need to reboot "

Hi

Well I got the replacement today, as an experiment I'm going to try the version 7 firmware exactly as before (already have the saved config) to see if it is any more stable, that way I will know if the original was faulty due to hardware, or if it was a software issue.

Some versions of the 8324 firmware seem to limit the number of telnet accesses in some way. I don't recall the details, but I guess the same might apply to the 8924.

Hi

Yes only one telnet session on the latest ZyXEL VMG8924 firmware.

Okay so been testing the replacement, okay so far, however on clicking around the Web GUI and keeping an eye on shared MBM memory, I saw the memory plummet to 84KB from 300+, so presumably the next visit or two to the GUI is going to result in a reboot.

Was the first one a hardware fault after all, we will never know.  The replacement seems a lot more stable than the first one was, it hasn't crashed yet, but obviously will do soon.  I'll try the new beta firmware.

I was just speculating really. DSLstats logs in and out before and after collecting each sample, so it doesn't by itself block telnet access to the device. But I was wondering if this model also has a problem with frequent telnet logins, leading to the problem you've got.

dslstats samples the stats ok here with my VMG8924-B10, in fact I run a script which also telnets in to the router once every half hour.
Yes, it does only allow 1 active telnet session but as roseway says dslstats logs out once it's taken the samples, it hasn't yet conflicted with my script's telnet access.

I would check if you have some other software accessing the router via telnet or if the PC's firewall is blocking telnet to the router.

Hi

Well on the version 7 firmware, as predicted due to the sudden drop of shared memory, after a couple of hours I've logged in to the Web GUI and it rebooted!

In the log I have "Out of MDM shared memory need to reboot"

Now updating to the beta 8 version.

Hi

No more memory leak on the 8 Beta 2 firmware, however I've managed to make it completely lock up in the same way as the first one and require a hard reset (paper clip to the hole at the back in order to get it to boot again) using the Email Logging feature.

I had set the email server to an internal IP of an SMTP server on my network, no user name/password required, and then set up the Email log with the SMTP server and then from the Log asked it to email the log, it then just gets stuck at the "Loading..." icon and essentially the web GUI and Telnet are non responsive.  The router didn't reboot itself as it has done before, I'm guessing that was due to the Shared MDM memory filling up before which it doesn't do now.  So all I could do was power off and back on again to where it no longer fully boots up.

I'll forward a bug report to ZyXEL, but not very impressed overall that such major bugs exist, they need to get these things tested.

So a warning, don't try and use the option of emailing out the event log.

Regards

Phil

You are having a bad time with the 8924 !!!

According to http://tjworld.net/wiki/Zyxel/VDSL_IAD#no1 (http://tjworld.net/wiki/Zyxel/VDSL_IAD#no1) [reference in Kitz Router page for the Zyxel 8324]:

The Motherboard for the 8324 & 8924 are the same, the 8924 has a Broadcom BCM4360 based mini-PCIe adapter in a mini-PCIe card slot.
The slot and associated components are not present in the VMG8324 although the solder pads are there. 


I am therefore finding the reboots etc surprising [NOT suggesting they are not happening]

I have the logging setup and e-mail alerts and it is working without memory problem(AFAIK)/reboots.
The difference is I am using the ver 6b1 firmware as are others on kitz.

Question:If you disable the Wireless on the Zyxel so it is not running any software related to Wireless comms , is it stable ?

In my case I am connecting to the Zyxel via an ASUS Router (RTAC56U) and not using any of the Wireless functionality on the Zyxel.
As stated it appears to be running OK. i.e. running for 18+ days since last re-sync with no known issues.

Hi

It is stable now on the beta 8 firmware, so definitely a firmware bug with the random reboots, apart from emailing the log which appears to be another firmware issue.

Are you using an external or internal SMTP server for emailing?

So my next try is to use a Remote Syslog program and send the logs remotely, this doesn't appear to work at all, no events reach the syslog server.

Does the job without the bother of setting-up & securing my own SMTP Server.

Hi

As it seems pretty stable now I've connected directly to VDSL via the ZyXEL rather than via the HG612, it gave an extra 1.5db of SNR, so up from 8 to 9.5.  Will see how it goes, but nice to have a one box solution and the extra SNR is a bit more protection from cross-talk.

My 8924 has now been up all day without the HG612 and seems fine. For now I have DSLStats issuing the meminfo command every 2 hours just to see how things go, if all OK after another 24 hours I'll stop the command. I do have max data rate set to limit my connection to 64995 kbps at present as when I did not use this my error rate was too high.

Yes, the NAT figure you see is the router keeping track automatically of connections going out via a single IP address to know where to forward them to when received back.  Unless you have a block of static IP addresses assigned to each internal device the router will be using NAT.

Hi, all, total novice here and i have the VMG8924 which i believe has been working perfectly for the week or so i have had it straight out the box and after following the set up guide on here.

i don't know what firmware i am using or how to upgrade it but i dont really  want to change anything as i have no problems that i am aware of but wondered if somebody would take a look at my stats and firmware and tell me what i actually have and if its good ?

I have done one reboot as i have only had the FTTC inifinity via plusnet for a few weeks and noticed the speed had dropped from 38mb to 20mb so did a quick reboot which brought it back up straight away.
The only problem is, i don't know what i should post for somebody to check..

I am not using a separate modem, it is wired straight to my BT mk3 filtered face plate via an ethernet cable up into my loft and down into my spare bedroom.

Any ideas much appreciated.

I'm still using one of the older f/w versions, so if you are happy and not seeing any problems then you can leave things alone if you wish.

As  regard to stats - do you have DSLstats installed?  Contents of the Stats tab or preferably from the  Telnet data > Connection stats is a good place to start :)

Ok, thanks, i have installed DSLstats, although i am using windows 7 64 bit the 32 bit version seems to work and my router wasn't listed so i selected the nearest and that also seems ok.
i have attached what i found and also my f/w version.

One question i was going to ask is that my max d/l speed says 46 mb but plusnet wouldn't allow me to buy the faster speed as they couldn't guarantee my speeds would exceed 40 mb, which is fair, so it is limited to 40 mb. I have never seen it above 39 mb, but is that because they limit it to 40 mb or would it be 39 mb even if it was the up to 80 mb service?

Its a little frustrating but i think where i am i am at the end of the copper wire as my mate around the corner can get 78 mb, so can my parents at the other end of the village and the next village along from us who share our exchange must have had a fibre cable installed to them as my friend there can also get 78 mb.

i did a check with the BT site by putting in various phone numbers and my neighbour can only get 38 mb as well so i dont think i have a problem.

G.INP is not active on your connection (it may benefit from it being applied).
DS Interleaving depth is fairly high at 753 & INP/delay have been applied (this is restricting sync speed by maybe 1.5 Mbps on your capped 40 Mbps service)
SNRM is around the target 6dB level (so not much hope of speed improvement unless interleaving is removed or G.INP is applied)


This could be due to:-

a) Being connected to an ECI DSLAM or
b) Being connected to a Huawei DSLAM that has not yet been updated to be G.INP capable.
c) The ZyXel's firmware needs updating??

Run the BT diagnostic speed test (further diagnostics) to find your IP Profile. If you can sync above 40 the BT IP Profile will be whatever can be achieved while the Plusnet current line speed will be 40. If the IP Profile is not above 40 you won't gain anything.

Thanks for the replies, some of that is way over my head as i and my local cabinet is brand new to fibre as it has only been enabled for a few weeks.

i have attached a pic of the bt test. When i did that the other day it was showing downstream as 46 mb and now it has dropped to 37 mb and i checked the plusnet portal current line speed which was at 40 and is now 37. the only thing i have changed is adding the DSLstats but that may be completely unrelated.

If you were a very early user on the cabinet it's not unusual to see a slow down as more users are added due to cross talk. If there's no reason to suspect there is an issue with the line causing slower speeds it would be pointless upgrading to Extra as any increase you might see would be minimal (if any).

Post by: jelv on May 01, 2015, 08:00:37 AM
That is my understanding: as cross talk increases the errors the DLM will reduce the sync speed to compensate. Perhaps someone with more knowledge could confirm?
Title: Re: New ZyXEL VMG8924-B10A Installed
Post by: Dray on May 01, 2015, 08:14:28 AM
DLM may increase interleaving or error-correction but I don't think it will reduce sync speed. My understanding is that cross-talk increases the noise meaning less SNR margin is available so a resync will sync at a lower speed.
Title: Re: New ZyXEL VMG8924-B10A Installed
Post by: Chrysalis on May 01, 2015, 08:27:40 AM
jelv its the crosstalk itself that creates noise on the line which in turn reduces snr.

The line can hold on with reduced snrm if the crosstalk isnt severe enough in which case is no immediate speed loss but would be speed loss the next time the line resyncs, or if the crosstalk is severe enough the reduced snr will cause the line to resync immediatly at a lower speed.

DLM would only intervene if the crosstalk also decreases stability in the form of either excessive resyncs or error rates.

I do have my own personal theory that the dslam in addition also adjusts power levels as more lines are enabled which would reduce sync speeds even further, but noone here or elsewhere agrees with me on that one :p
Title: Re: New ZyXEL VMG8924-B10A Installed
Post by: kitz on May 01, 2015, 10:29:44 AM
As Chrys says, its the reduction in SNRm that causes the loss of speed.

When a new line gets attached, the crosstalk generates more noise on the line which causes the SNRm to decrease and that in turn causes the reduction in sync speed.

-----------------------

If you are using DSLstats, then you can spot the signs of a cross-talker coming online.  You can sometimes even see when one of your crosstalkers has a resync or reboots their router.

For example heres my DSLstats SNRm graph and you can see that at about 1:20am one of my crosstalkers had a resync.   
Note how my SNRm momentarily goes up to 7.8 dB when he's not using his connection.
Then look what effect it has on my connection speed and how the max attainable jumps up.  This particular crosstalker 'costs me' 5Mbps of sync speed.

Its not anything that Ive ever seen and it would go against the rules why we have such things as PSD masks and PCB.   
There is one time when it may perhaps affect your Tx power and thats if an addition to the cab somehow affected your attention. The theory says this shouldnt happen, but its possible that a line may be disturbed when the engineer adds a line.   

If theres a change in attenuation then this could take you in to another bracket of the PSD masks as which PSD mask gets applied depends upon your line-length (measured using the atten).

Ive never seen my power change when a new line is applied.   For example Ive just gone back to the first set of DSLstats figures that I have to hand on this drive and when I first started using the Zyxel just over a year ago

SNR Margin(dB): 6.5 6.6 6.6
TX Power(dBm): 11.9 7.4 7.4

From this you can see over the past year that :

-  Ive lost a total of 7.5 Mbps of headline sync (Im now in year 2 and most of the loss was during the first year)
-  My Tx power has stayed the same despite more users being added to the cab - in fact my upstream has gone up slightly, which is reverse of your theory.
-  The SNRm has gone down (as expected) which has caused the attainable to go down.

I do have my own personal theory that the dslam adjusts power levels as more lines are enabled which would reduce sync speeds, but noone here or elsewhere agrees with me on that one :p

Its not anything that Ive ever seen and it would go against the rules why we have such things as PSD masks and PCB.   
There is one time when it may perhaps affect your Tx power and thats if an addition to the cab somehow affected your attention. The theory says this shouldnt happen, but its possible that a line may be disturbed when the engineer adds a line.   

If theres a change in attenuation then this could take you in to another bracket of the PSD masks as which PSD mask gets applied depends upon your line-length (measured using the atten).

Ive never seen my power change when a new line is applied.   For example Ive just gone back to the first set of DSLstats figures that I have to hand on this drive and when I first started using the Zyxel just over a year ago

FWIW, see the attached montage from my connection, starting January 2015.

Various stats have waxed & waned.

Over the years I have had my FTTC service, although not particularly highlighted in the 4 months of stats used for the montage, Line & Signal attenuation do gradually increase during summer & decrease in winter. That does have some effect on other stats/attainable rates etc.
August tends to be the period with the highest Line & Signal attenuation & lowest SNRM etc.

Got one of these routers and it's the most unstable buggy piece of crap I have ever used. The UI is awful and the modem reboots it's self at random times I also have the 8C0 firmware installed. The 7 series firmware was even worse with the modem rebooting every couple of hours and if you touched anything in the UI it would reboot. I just hope DLM doesn't kick in and cap my line..

Hi

I've had the same issues with early firmware however 8C0 has been stable and no crashing, with current uptime at 14 days.

The 7 version firmware did have a pretty bad memory leak which caused it to reboot every few hours or a lot sooner if using the Web UI.  This was fixed in verson 8C0, so I would double check your version is reported as 8C0 under the Firmware upgrade page.  It is also worth resetting to defaults and re-entering the configuration if you hadn't done this already when going from 7 to 8.

Also check the power supply is rated at 12 volt 2 amps.  Modems/routers with dual radios and high speed ac Wi-Fi draw quite a lot of power in bursts, so if not using the correct power supply will appear to work okay most of the time but then seemingly reboot.  Also enable the Log and check after a reboot if the cause of the reboot is shown.

Also I would suggest clearing your browser cache folder after any firmware update to ensure any scripts from the embedded web server are re-downloaded to avoid using out of date ones.

I do agree what you say about the Web UI, it is very slow at times and could be better.

Regards

Phil

Not sure if you have a VMG8924 or VMG8324 because of your mention of the power supply.

Not seen either of these problems with my 8324, although you do have to refresh the page after a PPP disconnect.

Aside from seeing this happen twice in one of the beta f/w's (cant recall now but its documented somewhere), but I rolled back and Ive not seen the problem since.  Up until 2 days ago when I had to turn my electricity supply off at the mains, then mine had been up for weeks and prior to that something like 3 months. All times have been me doing the power cycle. 

Im unsure if you have the correct power supply?

Either they have the wrong PSU or a duff router.

Yes the gui can be slow and is not particularly well designed but for me on both my 8324 and now on my 8924 (with correct PSU and using latest V8 release) have been fine. Mine has been up about 17+ days this time, and that was because I had a power problem in the house.

I do appear to have one issue with my 8924 on V8 firmware. That is I lose the ability to login via telnet or access the GUI via a web browser after a number of days of it being up. It seems a bit variable but between 12 and 20 days so far seems to be how long before it happens. The internet acces both by cable and wireless lans seem fine when it happens. As the only way I can see to recover access is to power off and on the router I am unable to see any valid logs to understand why this happens. I think it is time to try ZyXEL to see what they say.

Have you tried port forwarding yet? Having trouble knowing what to put in the WAN IP box as I have a dynamic IP address.

I left WAN IP blank and it worked for me, forwarding ports to my Synology DiskStation.

I have had the hang up again where telnet and local web interface stops working, so 10C0 does not fix this. I have fed back to ZyXEL that this still happens and they need to address it urgently. This time up time was 6 days before it happened. For now I'll leave it running this latest f/w as they may need me to test some stuff.

hi All

first post.  Just got this router (cheap off ebay) as i wanted to try a single box setup with wireless AC.  Ive upgraded the FW to 08c (got link from this thread thanks) and have connected over 2.4ghz WLAN SSID but the issue i am having is that the 5G WLAN SSID is not visible to any AC enabled devices on my network.  5G is enabled in the gui and the light for 5g is on on the front panel but i cannot see the SSID at all. 
Anyone had this issue before?  Im new to 5g so am i doing anything wrong?

I expect it is using a high channel number that isn't supported by mobile devices.  5GHz spectrum has a lot of rules and regulations about what can be used inside and outside, and mobile devices often being outside tend not to support all the frequencies of a router that will be used indoors.

To check this, change the 5GHz frequency a manual frequency of 36.

thanks Phil.  I switched channels to 36/80 manually as suggested but the SSID is still invisible on the network to all AC enabled devices (MBP, IPHONE 5s, experia android phone, dell pc)  No 5g networks detected using the wifi analyzer app on the droid either.

i actually mailed zyxel support this morning and got a response back saying the 8924 was not an AC device but and n device which is why i wasnt seeing the AC SSID.  I think they must be confused as i can see the 5g config in the GUI and the link light saying 5g on the face plate. :)

might it be a hardware fault with this particular 5g antenna?

Hi

That's a pitty it wasn't as simple as that.  It could be faulty of course.  The 5GHz is provided by a separate card installed on the main board so that could be faulty leaving 2.4GHz, which is part of the main board, working normally.

Have you tried a factory reset just in case?

The 8324 is only 2.4GHz, with the 8924 being AC so I expect support were getting confused.

If it helps mine is set to 802.11n/ac mixed, I've also set Regulatory mode to 802.11h (this is under the others tab) and channel is set to 40/80 at the moment, although 36/80 works as well.  Security is set to WPA2-PSK, Encryption is AES.

802.11n can operate on 5ghz also. the presence of 5ghz doesn't automatically mean it's AC, it could be dual band N.

thanks Phil...yes tried a few factory resets with no joy.  Ive also just tried those setting you are using and there is no difference either.  I am leaning towards the hardware issue although if it was hardware i am surprised it appears as a live connection in the GUI.  Ill see what support come back with.
Other than the 5g issues I am pretty impressed with this routers functionality.  It has endless configuration options and the sync rate from the modem is great so i would like to persist with getting it sorted if i can.

802.11n can operate on 5ghz also. the presence of 5ghz doesn't automatically mean it's AC, it could be dual band N.

ok thanks for pointing that out.  On the manufacturers site for this particular product the following wireless specs are listed

System Specifications

Quote
Wireless
IEEE 802.11ac 5 GHz with up to 1.3 Gbps data rate
IEEE 802.11n 2.4 GHz with up to 300 Mbps data rate

Wireless Protected Setup (WPS)
WEP data encryption (64/128 bit)
WPA/WPA2, WPA-PSK/WPA2-PSK
Wi-Fi scheduling
Multiple SSID (up to 4)

Regardless of whether or not they are AC or N, a 5Ghz device should see your 5Ghz based SSID as long as it is not hidden and of course it can handle the channel and channel width defined. Heck even if the internal antenna in the device was faulty you should still see it if up close albeit probably much weaker signal :P

Considering you did the best thing already and did a factory reset and you have some 5Ghz capable devices then it would be logical to assume that you bought a duff unit from ebay or something drastically went wrong with the firmware flash, you could try re-downloading the firmware again and try flashing again.

that what i thought should happen as well! :)  I am becoming more and more convinced this is some sort of hardware issue.  Support dont seem to be too hot...the latest i have had back from them is that i should change the 5g SSID to broadcast in B/G/N mode.....nice idea but the problem is that this SSID doesn't offer that option but only a/n/ac and mixed.   Running it in "a" only doesn't work either. I tried to set up an SNMP trap for the 5g interface but that interface not reporting any stats on SNMP.  At least support are responding and hopefully support escalate this to  second or third line soon.  Has anyone ever had anything repaired by Zyxel?

technically impossible, b/g are inherently 2.4ghz. a and ac are inherently 5ghz, only n can be either (or both). They use different radio hardware. it sounds like either the router doesn't do 5ghz, or its got a duff 5ghz radio unit.

Does not matter as in the settings for the 5Ghz band there will not be options for b or g, so not like he can do anything technically impossible :P

But I am digressing, it does seem like there is something wrong with his unit at least on the 5Ghz side :)

Sounds like it is broken to me.

2 more things that you might want to try -

1) Change the 5ghz ID to a simple word with no strange characters, no underscores etc. to see if that is causing it
2) Run wifi analyzer on your mobile devices to see if they can see anything broadcasting on 5ghz in your location

thanks for this.  tried both already.  no weird chars in the SSID.  Wifi Analyzer doesn't detect any 5g SSIDs in the house.  telling i think. SSID is not hidden

Unless, there was a case on here of someone who bought one and they got the wrong power supply with it and it wouldn't work properly. Have a quick look at your power supply and see if what Amps it is outputting.

yuo thanks.  ive already alerted the seller as to my suspicions re the hardware fault and told them i am speaking to support about it as i do want to get it resolved if i can.  it was pretty cheap after all! :)  if support dont want to fix it then ill send it back to the seller.   They have a 100 percent reputation and loads of sales on ebay so i dont think it will be an issue.

Well I've just heard from ZyXEL about my hang issue which still happens on 10C0 and they want me to RMA it. Good job I have other routers I can use or I'd be stuffed. Will probably put the TT HG635 back in and run that, as it has 5ghz wi-fi and does not suffer from the hangs. Not sure why they think my 8924 is faulty they are not saying anything except RMA it so I guess I'll have to wait and see.

Just had the hang again on my 8924 with DSLStats not being able to login. So I thought I'd try putty with SSH and guess what I was able to login OK, and then DSLStats was able to login again using telnet and continue gathering stats. So now I am wondering if this could be something to do with DSLStats not logging out correctly maybe? Using SSH I use the same user/password which DSLStats uses. I wonder? The web gui is working again as well.

You may be on to something about the Zyxel 'hangs'

Practically every time I log in to do config changes then DSLstats will report something like

Quote
17 Jun 2015 12:52:46   Timeout while collecting system uptime
17 Jun 2015 12:52:46   Telnet timeout
17 Jun 2015 13:02:47   Timeout while collecting system uptime
17 Jun 2015 13:02:47   Telnet timeout
17 Jun 2015 13:30:46   Timeout while collecting pbParams data
17 Jun 2015 13:30:46   Telnet timeout

It certainly doesnt appear to like it when more than one login is attempted.

Eric is going to add some more checks on logout in DSLStats which might show if that has any problem logging out. Earlier today I was trying to telnet into the router manually and it rejected it because there was already an active session so it shows it only allows a single telnet session because I had not input the user so it was not rejecting the user but any telnet session.

update on my 5G issue with this router.  I got another unit from the ebay vendor.  upon booting the new unit the 5g WLAN SSID is  now visible so the issue i was having  was definitely hardware related and the original unit is faulty.  5G Wifi working fine now!

I have done a test on telnet with this router. I had to turn the house power off yesterday to do some re-wiring and so once all was back on again I tried to telnet into the router while DSLStats was sampling and sure enough it failed. I did this just in case my previous test was skewed by the problem I had with the hang, so after a clean power up it shows that this router only allows a single telnet session at any one time. Now I will install Eric's latest update to see if it shows any telnet problems as he has added extra tests in the logout process to ensure a clean logout.

I now have Eric's test version of DSLStats running which might shed some light n this telnet issue. I noted on the DSLStats thread Kitz mentioned a timeout, well I see that usually on start up of DSLStats and in my case I know there is nothing going on via the GUI at the time I see these messages
Code: [Select]
21 Jun 2015 19:53:43 IP address is now xxxxxxxxx
21 Jun 2015 20:06:42 Timeout while collecting vendor data
21 Jun 2015 20:06:42 Telnet timeout

As yet I've seen nothing to indicate there has been any logout failure on telnet. I will contact ZyXEL and tell them what I am doing, explain my findings about SSH  and ask if they can increase the number of telnet sessions allowed.

hi again all

what is the general experience when dealing with Zyxel support?  I have been in communication with their first line support regarding the issue with wifi i have discussed in this thread.  Whilst the response form first line has been forthcoming it hasn't always been useful or timely.  Has anyone managed to get past first line and deal with lower level support teams?  If so, what has this been like.  Has anyone actually had any hardware repaired by Zyxel in the UK?  The person i bough the router off has kindly allowed me to keep the original faulty unit in addition to the new one that is fully functional. The original unit is fine apart from the dodgy 5g radio and I was hoping to get the 5g hardware repaired and use it as a 5g AP in another room

So far I've only raised a ticket via their website and responded to their email but it has been slow and not very helpful. Kitz suggested I call them which I will do maybe tomorrow. They did suggest I RMA the router I have but not sure any replacement would fix the issue I have so will try to progress via telephone.

Ive used their ticket system once and it wasn't blistering fast, but they did respond within a day.   Ive used their telephone service a few times,  usually have to hold for about 10mins and if they cant assist there and then they call back.

As regard to reporting bugs, Ive found them quite responsive although perhaps not as quick as TPlink when it comes to realising updated f/w (they usually send a beta through quite soon before general release).   They seems to be sticking a bit in the mud though about my request to increase telnet sessions :(

This morning I had a chance to phone ZyXEL about my findings with telnet, SSH and Web interface etc. I did not get a whole lot out of the level 1 guy I spoke with (trying to understand his very thick foreign accent), however he did promise to pass my comments up the line and ask them to get back to me on what they thought as to how SSH resets the telnet issue. I explained that at present I saw no point in RMAing the router as I believe this is a f/w bug. I did also mention it would be good if they allowed at least two telnet sessions.

I await a response....

Since flipping from a HG612 with Asus DSL-AC68U as a router to a VMG8924-B10a I get a steady increase of FEC from very low after a power off reboot, then every 7 hours or so it goes up by a few hundred thousand. Today it's running at 4.5million. I did not get this with the HG612.

I bought it hoping the newer Broadcom chipset would help get me out interleaving, or at least wake up my DSLAM into putting G.INP back on my connection instead of oldskool interleaving.

Any one else had this FEC(ing) problem? I'm about to downgrade the firmware to 8C0, see if that helps. Else maybe it's faulty?

I had one yesterday but using an older version.   Because Im hardly here atm I dont have any time to investigate but at first glance it looked like a dup HG612modem stats stuck .exe,  which then caused dslstats to error,  may have triggered the lock-out.    If BE1 is reading this, sorry atm I'm really not around to do any testing but I am beginning to suspect that the use of monitoring progs may be triggering lockouts :(

Hi

I expect it is some form of memory leak, the more features you turn off the more free memory is free at the start and the longer before the issue manifests itself perhaps?

I'm on the 11b2 firmware now, and I've been playing about a lot with QoS and other settings.  Usually after a lot of playing about in the Web GUI the UI has ended up crashing followed by a reboot shortly afterwards but on 11b2 it's been solid.  Fingers crossed, I expect the next time I go into the WebUI it will crash now  ::)

Hi

Just wanted to make mention that the ZyXEL has an RF filter in it which I've not seen in other devices before, which might explain my slightly on average 0.5 to 1db extra margin.  The filter is a UT34297B by UMEC.  Might be an advantage on extra noisy or long lines.

Hi

I've not seen an internal filter before on a modem, the good thing about it is that it is as close as you can get before the ADSL/VDSL is processed by modem, so any noise picked up very locally on the telephone wire used to plug it in should get rejected, although for best results a twisted pair telephone wire should be used rather than flat oval type.

Data sheet  (http://www.umec-web.net/downloadfilemagnetci.php?id=3739)

I would suspect if people are finding the ZyXEL is a good performer on their line that it is possibly down to this extra filter.

Regards

Just to say that my 8924 has been running now with no interruptions for nearly 37 days (probably tempted fate now  ;) ) so I inclined to believe that my issue was at least exacerbated by logging (now turned off) probably using too much memory. I'm still running 10C0 for now. I might try 11C0 soon but while it works I dont want to change anything right now.

my 8924 has been up for 37 days now on 1.00(AAKL.10)C0 of the firmware.  During that time i have not had any line drops but did have one reconnect on the PPPoE 15 or so days ago but i guess this was initiated by the ISP?  The GUI has generally been stable but there are the a few bugs that are noticeable.  It sometimes reports that I've lost connection to the ISP/internet but this is not the case.  It also sometimes shows the WLAN as being down but again this is not the case as these are visible and usable on the network.  These issues are more annoyances rather than anting else and i have been happy with the general performance so far.

As Chrys says, its the reduction in SNRm that causes the loss of speed.

When a new line gets attached, the crosstalk generates more noise on the line which causes the SNRm to decrease and that in turn causes the reduction in sync speed.

-----------------------

If you are using DSLstats, then you can spot the signs of a cross-talker coming online.  You can sometimes even see when one of your crosstalkers has a resync or reboots their router.

For example heres my DSLstats SNRm graph and you can see that at about 1:20am one of my crosstalkers had a resync.   
Note how my SNRm momentarily goes up to 7.8 dB when he's not using his connection.
Then look what effect it has on my connection speed and how the max attainable jumps up.  This particular crosstalker 'costs me' 5Mbps of sync speed.

Hopefully it's ok to drag up an old thread but I have an update.
I have had the Zyxel since the middle of last year and it has been faultless but my line speed as been steadily dropping off as can be seen on the attached which i am guessing is due to cross talk as already mentioned. i am using version 8 firmware and my speed has dropped from around 38 Mbps to now around 32 Mbps. Is there anything i am doing wrong or that looks wrong from the attached please ?
i have DSLstats if there is anything i could post from that.
Apologies if i should have started a new thread.
Thanks

If you don't already, you may want to use DSLStats to upload your data to https://www.mydslwebstats.co.uk/

You may also want to try an updated version of the firmware - the 8324/8924 is now up to v.14 - and may now include newer broadcom code than v8.

Thanks for the reply, i have updated the firmware to version 13 as i could only see version 14 for the 8324.

I had a look at the link which looks good and i have found the 'My DSL Stats' part of the DSL Stats program so i will register. There is a wealth of information that it would be handy for those in the know to have a look at.
As i was one of the first to get VDSL out in our village i would imagine there are a lot more users now than when i joined.
The only other thing that has changed is i have added cabled CCTV into my house which also  uses wifi to talk to alarm sensors and i also have the power cables for the DVDR recorder running near to my router cable running from my front door via my loft to my Zyxel upstairs.
I'll register for the My DSL Stats and report back.

The 8324 and 8924 are identical apart from the 5ghz wi-fi on the 8924, they use the same f/w as ZyXEL only show the 8324 on their sites as the f/w is the same.

I also would be careful about v14 until we know more about it as it is still not on any ZyXEL site I can find.

Both applications work but I get repeated "minutes" lost with both .must be a telnet issue I would think on the router. Stuck at 93% at the moment.  I am using it in modem/bridge mode. Will see how it goes over the next day or 2. Interested to see if it gets less errors than the billion which has a high ds es rate..

Just a thought.....................

Do you have both programs running at the same time?
If so, is HG612 Modem Stats co-operation set within DSLStats to ensure a suitable time stagger between each program attempting to access the modem's stats at the same time?

How long does each program typically take to complete a data harvest?
The ONGOING_ERROR.LOG_file_ERROR.TXT file should confirm that for HG612 Modem Stats.

You should find it in my dropbox at https://www.dropbox.com/s/1ktxmfp6mk7sbod/V100AAKL14C0.bin?dl=0 (https://www.dropbox.com/s/1ktxmfp6mk7sbod/V100AAKL14C0.bin?dl=0) but beware we have not found this version on any of the official ZyXEL sites as yet so it might be a bit of an unknown quantity.

I'll give it a try but where was that file originally sourced?

Won't use this as a modem yet though incase of reboots.

V14 out now?

Isn't that for the 8324 version or is the same firmware shared with 8924?

Thanks, I really wasn't aware of that until now.

Does anyone know roughly how long the included power cable is? Thinking about placing this high above a cupboard.

I think I'm going to need a mains extension cable. 145cm is not long enough.
