Kitz,
I have followed the 'Kitz guide' to setup the Zyxel modem on vdsl but I cannot get a connection. It does work via adsl.
It does work if I use the OR Huawei HG612 modem, with the same username/password, via an Asus RT-AC56U router.
I seem to remember seeing you are also on PlusNet.
Are there any particular settings that are needed to make it work with PlusNet ?
(Yes... I have correctly typed the username/password, Many Times via Chrome & Firefox !!! ;D ;D)
I have tried the settings in the guide + read through the BT SIN 498 Issue 5.1 September 2013' applying every feature BT states is required of any 'CP provided modems that must be met for connection to Openreach User Network Interface (UNI)'.
(BTW: the BT SIN is an interesting read for anyone outside the industry, or is that 'Just Me'!!!!!. ;D ;D)
I have now run out of ideas.
Any assistance appreciated.

To reply to my own message (Sorry!!!)
Problem solved. ;D
Once again followed the guide at http://www.kitz.co.uk/routers/zyxel_VMG8324-B10A_vdsl_setup.htm (http://www.kitz.co.uk/routers/zyxel_VMG8324-B10A_vdsl_setup.htm) , after reseting the Zyxel modem.
The menu options changed so something must have been screwed up. ???
Additionally, disabled PhyR Ds & PhyR Us & SRA (On by default) it is now working ;D ;D ;D
I am getting 9 Mbps more 'Attainable Net Data Rate' than the Openreach HG612 Modem.
Very happy 'bunny' ;D :D ;D :D ..... I have escaped from SKY (long story) and have at last got a fast line (Compared to 3.5-4 Meg).

Superb. I owe Kitz £5 :)

Sorry - only just seen this thread, but glad you got it sorted.
Additionally, disabled PhyR Ds & PhyR Us & SRA (On by default) it is now working
Just noticed that by default mine were set as (and still are)
Annex M - disable
PhyR US - disable
PhyR DS - Enable
SRA - Enable
So it obviously cant matter, if the technology (such s SRA) isnt available then its not going to be able to use it anyhow.
I am getting 9 Mbps more 'Attainable Net Data Rate' than the Openreach HG612 Modem.
Yes I got a nice large increase too. I think most people that used it have. :)
Nice stats btw. Your HG12stats are iirc similar to mine when I first went live & after a line fault fix. My atten is just slightly less. Is that a new cab?
Very happy 'bunny'
I hope you continue to be as happy with it as I am with mine. There's a few small quirks (mostly the Firefox issue) but aside from that I really like it. Also Ive found the wifi range pretty damn good compared to others.

Unexpected, but thank you very much. It goes in the pot towards next months hosting fees :)

I would agree with you as this BT SIN http://www.sinet.bt.com/sinet/SINs/pdf/498v5p1a.pdf (http://www.sinet.bt.com/sinet/SINs/pdf/498v5p1a.pdf) states that PhyR DS/US + SRA should be supported and hence if enabled should NOT stop the connection.
Yet, I tried connecting with identical defaults to you and it 'Failed', I enabled PhyR DS/US + SRA and it 'Failed'.
Only when I disabled them did it connect. I repeated this 2 times to check if it was a fluke and it was not ???.
Maybe the line is misconfigured ?
The POTS cab is very old (Huawei CAB [Fibre] new) and was wired in 'reverse' to quote the OR Engineer.
I watched the line being enabled (2nd in cab) and after escalating a call back to OR it was discovered the punchdown block was wired the opposite to normal. OR Network Ops, back at base, reset/re-enabled the line as part of the diagnostic process to discover the fault.
The Engineer had to write on the inside of the Cab door a note to advise the wiring had been reversed otherwise every Engineer would be raising a call with OR when their line did not work.???
I hope you continue to be as happy with it as I am with mine. There's a few small quirks (mostly the Firefox issue) but aside from that I really like it. Also Ive found the wifi range pretty damn good compared to others.
Very happy but a quirk I am 'Fighting' is when I open the web address for the Zyxel (192.168.x.x) it does not always finish displaying the page and hangs with a busy cursor spining. This can be got past, most times, by backpaging in Firefox and retrying.
The same thing happens with the ASUS RT-AC56U. I have swapped cables (Cat 6)/network card(Intel CT Adapter) and Gigabit switch (TP-Link TL-SG1008D) for all new items and it only affects the Zyxel & RT-AC56U ???
I have re-installed Firefox,could it be a Firefox problem?
Chrome will not install ???.
It crashes during the end of the install with no message other than 'Sorry Chrome has crashed. Do you want to restart ?'.
Restarting crashes again ???
Update:
Fixed, NOT a problem with either the Zyxel VMG8324 or Asus RT-AC56U ;D ;D
Turned out to be related to Firefox Add-ons corrupt or fighting each other ???
Re-Installed Firefox again and wiped all Addon-ons then added again and working OK.
Still cannot use Chrome but no loss to me !!!!
So lots of fun !!!!!
Late News:
(OR DLM has just pushed the 'Attainable' to 120 Mbps and 'Actual' down to 72.55 Mbps :( :( )
-

Wonder if it is anything to do with the dslam set-up then. Im on an ECI cab which doesnt seem to mind.
it only affects the Zyxel & RT-AC56U
Sorry not sure what that could be. Some sort of caching issue? :hmm:
I use Firefox as my main browser and the only issue I did have is with the save button not working for line config changes page. I view stats and access the router most of the time with FF. I was doing some testing the other week with the wifi and I was changing those settings fine in firefox.
Sometimes the 'login' button image is a bit slow to load, but Im talking about 1 or 2 seconds, so nothing major.
Chrome will not install
Have you tried the alternative installer?

hmmmm has the DLM just applied interleaving? It sounds like it may have - the increase in attainable sometimes happens when it does.
I hope its not the DLM being aggressive because you have been turning off and plugging in new routers? :(

Could be.
Could explain why SIN 498 states 'Should support PhyR + SRA etc'.
Maybe some parts of the OR network are different for whatever reason !!!
As you stated it should not affect anything if not there.
Although SRA would be usefull instead of DLM jumping around with BIG lags before/after changes.

Thanks, trying this now.

I was aware of the risks changing routers while DLM was running BUT you get the 1st 2 days on 'full bore' so to speak and power offs should not change anything.
Also I used the 'Dying Gasp' by pulling power NOT removing the DSL cable & waited at least 30 mins before switching back on.
[Hard Hat on]
I know there is some debate about 'Dying Gasp' but it is in the SIN !!!!.
I can only assume that BT/OR document what they do not what they should do.
Although 'Real World' experience in all industries has demonstrated 'assuming' is not to be relied on !!! :D ;D :D

When things have settled down it would be interesting to compare error rates on the Zyxel with those on the HG612. The Zyxel i had gave more than 5 times the error rate of the HG612 with the same sync speeds -- it was sent back. Kitz reported no change in error rates. Mine may have been faulty as i suspected or it may be just my line that Zyxel did not like.

Give me until the 10 days of 'DLM Hell' is over then I will get whatever stats you need.

Although SRA would be usefull instead of DLM jumping around with BIG lags before/after changes.
A little birdy told me that next year BT may well be dabbling into the world of SRA.
They are also already quietly playing with PhyR/G.INP on some lines.

Very good to know.
It looks as though BT are starting to test/use all the 'Hidden' features in the Openreach supplied modems & OR Compatible ISP Supplied modems.
Maybe the SIN 498 requirements are actually inclusive of 'Future Planning' ?????? :o :o :
[No, must be a mistake surely ;D ;D ;D <jk>]

Do you have any details on this i.e. what we should be looking for/monitoring?
-
No it was quite vague, but implied that SRA may be trialled after vectoring.
Re phyR the impression I got was that this is already being tested both on adsl2+ and vdsl. There wasn't much indication as to which group/area/region was selected. It was deemed that EUs probably wouldn't notice.
I also got a hint (but how true I don't know) that there may be a hardware solution for vectoring on ECI cabs. I'm not too convinced about that yet though so don't get hopes up on that score.

SRA isn't particularly new. It's an adsl technology that has been around for a while. UkOnline LLU used to use SRA with adsl2+ since circa 2006 at a time when bt was only just introducing adsl max.
PhyR is iirc a Broadcom invention that is also a few years old now. I know that both me and BE have seen weird indications that phyR could possibly be in use and we've discussed it on here too.
It's one of the possible reasons why some of us on occasions could see FECs on a non interleaved line.

As per the attached graphs from my connection (currently non-interleaved).
You can see when Interleaving was switched off (26th August).
FEC errors almost disappear, but I do still see some.
Using the original Asbokid unlocked firmware, I never saw any DS FEC errors on the odd occasions that my connection operated on fastpath.

I never got around to putting Wolfies f/w on my HG612, yet I'd see some in the upstream

Sorry AArdwark for taking your original thread slightly off topic, but since the original query was sorted and the thread developed on to this conversation, I hope you dont mind :)

Ive just this moment seen something else which would indeed confirm that trials is scheduled for next year. Thank you to the kind purrson that sent me the info ;)

Sorry Late reply, I have been somewhat diverted re-using 'old' routers as wireless extenders on my 'Home-Lan' and fighting a Sky Now TV box to get it to work !!! (I won in the end ;D)
All good to know.
I was aware of SRA and PhyR, hence the interest in BT actually using it.
Having had a long & noisy line (Read: Slow !) for years I appreciate any Technologies that can 'wring' the maximum performance out of the line.
BTW: Take this thread wherever it wants to go, I don't mind at all ;D
