Title: Line stats. What do you make of them. I am considering replacing my old BT Voyag
Post by: Gummby on October 13, 2011, 02:46:29 PM
Hi

I was advised by Kitz to post this here.

I am having syncing issues with my local exchange. I believe it is the modem. (BT Voyager 210. probably an over heating issue on the modem?

I am currently with Vispa ISP on ADSL 2+.

I was considering a netgear 834 modem to replace my current one.

I have had an engineer round who replaced some part on my BT socket. He states the line was fine.

Anyway. Any thought on the below line info.

Noise Margin    25.0 dB    30.1 dB   

Sync speed obviously very low for the attenuation. 
Can you reboot the router and post another set of stats immediately after the reboot please

If I reboot it may take me anything from 30 mins to 2 hours to reconnect.  I assume you mean restart the router? I can turn it on and off. ;)

Is that noice margin low??? Is that the issue??

The noise margin is waaaay too high... 
Your line should be syncing at about twice the speed of what it is for your attenuation.

Rebooting the router (turning off/on) and taking some fresh stats immediately after resync should give a clearer indication of what the msan in the exchange is seeing from your line and help see what kind of target profile you are on.

Theres obviously an issue with noise somewhere, not sure from whats posted above so far, whether its the physical line/REIN or the router.

...  and can I ask the other forum members to perhaps come up with some possible suggestions for a good replacement router as Im a bit out of touch with whats the latest available on the market.

Budget £50 max - wireless not essential.

For a replacement router I wouldn't recommend the Netgear DG834(G) unless you can get one of the earlier v4 versions, which has a Broadcom chipset. The current v5 version has rather poor performance due to its Conexant chipset. In general, Broadcom-based routers are reliable performers, and one of the latest ones, the Billion 7700N, is getting good reviews.

For a really cheap option you could get a BT Business hub 2700HGV from Ebay, and these are widely respected for their performance on long and difficult lines, but on your fairly short line they may not be so good, compared to Broadcom types.

Post by: roseway on October 13, 2011, 04:50:22 PM
Those stats are essentially identical to the earlier ones, and as Kitz said, you have a very high downstream noise margin. It rather looks as though your speed has been capped at 6654 kbps (although this may just be coincidence), and I think you should ask your ISP to confirm or rule out this possibility.

Otherwise, your suggestion that the modem is the cause of the problem looks quite possible, and really the only way to be certain about this is to replace it.

Post by: Gummby on October 13, 2011, 05:08:14 PM
Is this high noise margin an issue? Does this mean I am too far away from the exchange? ?? Is this likely to stop me getting FTTC connection in future months??

Could it also be that I am in flats and the flats seem to have wires going from a central cabinet to all the flats? More cable can't be a good thing.

I did wonder about my line speed. I emailed vispa a week or so back and they stated I was on up to 24mb service. Clearly i am only reach a fraction of that speed.


As for the modem. Billion 7700N. if i get a wireless one is there a way to disable the wireless aspect. I certainly don't want free loaders on my broadband. It is also unclear if Modems from retailers automatically enable the best WPA2-psk settings.

Post by: Oranged on October 13, 2011, 06:15:17 PM
Are you using one of those plug-in telephone extension leads (as sold in DIY outlets) anywhere in your flat ?

Just to explain what everybody has been saying re. noise margin and sync speed, I'm just a little further than you from the exchange and these are my stats on an ADSL2+ connection :

Quote
Bandwidth (Up/Down) [kbps/kbps]:   1,313 / 9,411
Data Transferred (Sent/Received) [kB/kB]:   0.00 / 0.00
Output Power (Up/Down) [dBm]:   12.0 / 19.0
Line Attenuation (Up/Down) [dB]:   19.5 / 38.5
SN Margin (Up/Down) [dB]:   7.0 / 6.0

So if your noise margin was similar to mine (which it should be) then your connection speed would be near 15000kbps rather than the 6654kbps that it is currently.

Just a thought re. your comment about the phone cabling within the flats....it is quite possible that this may be a cause. If the flats are relatively new then the cabling was probably installed by the builders/electricians rather than a telecomms engineer.
Title: Re: Line stats. What do you make of them. I am considering replacing my old BT Voyag
Post by: roseway on October 13, 2011, 06:37:07 PM
What Oranged says is right, but bad phone cabling wouldn't explain the very high noise margin. Something else is holding your speed down and your noise margin up, either a cap (or deliberatly high target noise margin) or a disfunctional router.
Title: Re: Line stats. What do you make of them. I am considering replacing my old BT Voyag
Post by: HPsauce on October 13, 2011, 06:45:09 PM
either a cap
That gets my vote.  ;)
The upstream speed of 444 is suspiciously close to 448 that you usually get with ADSL1.
(and I think I've seen on other capped lines)

That said, finding out who has applied it and whether they'll remove it may not be easy.

Trying another router first is a necessary step in diagnosis whatever the cause.

Post by: kitz on October 13, 2011, 06:48:33 PM
Thanks for posting the 2nd set of stats.   

The reboot at 6654 looks like something is capping your speed.  The additional SNR means that you 'should' be getting much higher speeds.

Your current router the Voyager 210 should support up to 24Mbps and is adsl2+ compatible, but they are a bit old now.

I believe 6656kbps is a common cap that can be set by BTw on the DLM to help stability.  Check with your ISP...  but from your attenuation, your line should be able to support about at least double what you are getting.

Thanks for the recommendation of the Billion Eric, wasnt sure what others would suggest.  I'd already suggested trying to get hold of a v4 netgear with the broadcom chipset via PM, but these seem a bit difficult to source now and most seem to be the v5 with the connexant chipset.

If the BTo engineer has tested the line and says its fine, then the Billion may be the way to go to ensure that its not the router that causing problems.... but I still think that line is capped.

Bit hard to say from the 1st set of stats since it had only been recording for a couple of hours, but the amount of errors doesnt give me any cause for concern and are all RS corrected.  Theres no CRC/HECs, so it looks as if its been stable up to that point of reboot.

Would be interesting to perhaps monitor over a longer period to say for sure... as it is possible for noise bursts to occur at certain times of the day.

Gummby - did you do the boot at about mid-day... or was that just uptime since the engineer had visited.. or did it resync itself?
Title: Re: Line stats. What do you make of them. I am considering replacing my old BT Voyag
Post by: Gummby on October 13, 2011, 08:19:34 PM
Are there any other suggested modem beyond the Billion one?? I want to get one delivered next day and I can only find one on Amazon of the firms I know.

The engineer visited a few weeks back and it seemed to work fine for a while. I had 3-4 modems to test the line on. 2 Bt Voyagers 210 of which one he said was faulty. Clearly the second is. A BT Voyager 220V which does not seem to work. An old adsl modem which does seem to link up to the exchange but does not support adsl 2/2+.

I would agree it does seem like my broadband has been capped. They do say they let the broadband settle at a stable speed. Perhaps that is what they have done?

I didn't boot at midday that was probably they time my service resumed this am. I think as i turn off all sockets at night the modem has to reset each morning. So each morning it need to resync with the exchange. here it fails.

I think the first step is to replace the modem. I need to order one of these while my service is still up.

Thanks for all the advice so far. Lots of interesting opinions. Keep any advice coming.

Routers are designed to be left on 24/7 and they use very little power.  There is some strong debate over turning the router off at night.. and although the DLM should in theory be able to cope with one power off per day, its not unknown for it to be fooled in to thinking that its a disconnect for other reasons and adjust profiles wrongly.

Myself, Im strongly of the opinion that the router should remain on all the time.  Im on a very short line, but in the past have had so many problems with this line being capped wrongly.  Seriously Ive been capped after power cuts or when I had an electrician working here and he pulled the switch on fuse-box before letting me power down.  I've been hit with the stuck bRAS profile problems so many times that its one of the reasons I couldnt wait to get away from BT's DLM.  ???

I dont have a Billion myself, but I should assume it will be very easy to change in the config...  if not there are several on here who do have this router who will be able to guide you if you run into problems.


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

btw just had a quick look at that linky, they are talking about Annex_M settings and it looks like a Be* connection.   
BTw based systems dont use Annex_M so you will be fine with the normal adsl2+ settings.   Some routers wont work on Annex_M (used by Be*) without firmware upgrades.. or some wont work at all.  Be* has slightly different settings than most other ISPs, but since youre not with them, you wont need to worry about this.

Oh so perhaps this is why my line is being capped? I just always turn everything off to save on electricity. Afterall I don't want a fire due to an electrical fault on a router. The BT voyager always runs pretty hot!! It is a bit of a habit turning it off. Perhaps I should just leave it turned on 24/7 if this is leading me to being capped?  Not sure how much electricity it actaully uses.

From what I have read the BT Voyager 210 suffers from over heating. From my testing the issue is not syncing up with the exchange on the old modem. I think it is this modem that is faulty. Not 100% hmmmm.

Not sure how much electricity it actaully uses.
Interesting question, that's cropped up before.  I've just plugged my DG834GT into a the wall socket through a wattmeter, and it reads 7 watts at idle.  I seem to recall a rule of thumb that a watt is vaguely comparable to a bit less than £1 per year, so let's say £6 per year in electricity, if left on 24/7, compared to £4 a year if switched off for eight hours overnight.

Further, I don't want to side-track this into a debate on the philosophy of energy usage (we've done it to death in other threads), but remember that any energy your router uses is dissipated as heat, which means there is less work for your central heating to do when it fires up in the morning.  Hence in the winter months, whatever small amount the router adds to your electrical bill,  a portion of it will be repaid by a small saving on your gas bill (assuming gas CH).  So I'm going to hazard a guess at perhaps £1.50 per year to keep a router on 24/7 comprised of £2 overhead in electricity, and a 50p saving on gas CH.

But it's late, others may find flaws in my calculations :)

Hi
As Roseway says No, a cap is a deliberate decision by the ISP, not the result of any automatic response.

and the Noise margin is an indication of this
quote  Noise Margin    23.5 dB    28.7 dB   
         Line Attenuation    30.5 dB    14.1 dB   

DLM will only increase target margin to 15db in steps of 3db  if it detects an unstable connection it may also increase interleave depth where there are lots of CRCs. so  your DS SNR margin has been applied by your ISP.

Ethernet. I don't think the BT Voyager has a USB point. Either that or I never used the right cable.

Is USb quicker than Ethernet.

I think when I get the new modem i will leave it on 24/7.  £7 a year seems small fry. I certainly don't want to trigger an environmental debate. I was more concerned about the modem over heating than the cost of running it 24/7.

When I get the new modem installed I will look at getting the settings redone and going to the ISP with soem figures on the speed side. 6mb speed is rubbish really.

For what it's worth, I share your concern over fire hazard it's something I could worry about quite a lot, if I allowed myself to do so.   I can remember, as a teen-ager of the 1970s, my father actually switched both gas & electric off at the mains before going to bed, just for peace of mind.

But it (leaving things on 24/7) seems to have become unavoidable in many aspects of the technological age.  DECT phones for example, fridges, intruder alarms, the list is endless.  My view is that I just have to trust the manufacturer to ensure the risk is very very low, (and make sure my home insurance is up to date!).   

Even my car, I recently discovered, springs to life while locked up in the garage in the wee small hours, running its ventilation fans at full speed for 10 minutes to deodorise the system.

And in fairness I do suspect that modern electronics apparatus is several orders of magnitude safer than that of 50 years ago.

The Ethernet port is much preferred if your PC is suitably equipped.  ;)

Yeah it does have a USb port. I was thinking the end that went into the pc not visa versa.

The modem has arrived. Not had a chance to install it yet.

Okay I have hit 2 snags

Firstly my cd rom drive has vanished. Looking at the drive details it looks like it does not like the driver. I hope there is nothing more sinister to this problem. Quite honestly I hadn't even noticed I had an issue there.

The main issue is I can't get the modem or the old modem set up to work. My line says it is connected but only locally.

Pretty sure I got the username and password right. I had to set it up manually.

Used 0/38 on vci and PPOA  thing. All the details on network screen show as set automatically.

Does it make a difference if I have a static IP address on Vispa?? Do vista use sepcific settings?? I am looking on their site now but the knowledge page seems to have some issues.

HELP lol

Currently at parents trying tom get driver for the cd rom. USB pens could save my life.

Don't panic. :)

You don't need any driver or setup software, so I suggest that you stick the CD in a cupboard and forget about it.

If you can connect to the router using a browser then your computer's ethernet interface is working properly. All you have to do is enter the correct configuration settings. In my 7800N there's a section in its web interface called 'Quick start'. If the 7700N has a similar section, you should be able to use it and allow most of the settings to be automatically detected. The only details you should have to enter manually are your ISP login name and password, and you must get that right.

I'll have a look to see if the router manual is available online but it may not be there yet.

Used the quick start up.

I am not sure if I used the correct details as the network  status at bottom right of screen said local only and not 'local and internet'. Perhaps I got the login details wrong. I don't think I did. I certainly got something wrong.

Be it the VCI numbers or something else.

I couldn't even get my old BT voyager to work again.

The issue with the CD rom I am going to try a registry edit to fix. I can't find the drivers online.Dell don't seem to list my model. Grrrr.

There's no obvious reason why the Voyager shouldn't still work. Have you changed anything else (different ADSL filter, different connection leads, etc.)? If you use the original components, and make sure that everything is plugged in correctly I can't see why it shouldn't work.

I wonder if the cd rom issue is linked at all. Bizarre

Okay worked some magic and I can now use the CD rom drive!!! Basically played with regedit and removed the upper and lower filter of the registrey key as suggested by Microsoft.

So using the cd  ;) I installed the modem settings. Suprise, suprise I am now online. I think the main issue was the cd rom drive vanished from my computers.

I disabled the wifi part of the router. Of course I could use that for my mobile??? Not sure if I am ready to play with the modem again.   :-\

Anyway time to check my settings again and see what speed I am getting now. Thanks for all the help. I really don't think it was something you could easily fix without being in front of the pc.

Post by: Gummby on October 16, 2011, 11:51:44 PM
Had a final thought on this. Does it matter which lan port you use on the router? Could this be why I got no internet??

Hmmm I guess I should be happy it worked. Although it would be nice how to manually set it up in future without a cd.
Title: Re: Line stats. What do you make of them. I am considering replacing my old BT Voyag
Post by: roseway on October 17, 2011, 06:54:12 AM
No, it makes no difference which LAN port you use. I'm still puzzled as to why manual setting up didn't work, but I guess it must be some less obvious configuration setting which was missed.

Anyway, I'm glad it's working now, and it will be interesting to see how it performs.

On the subject of WiFi, you wouldn't be able to use it for your mobile, unless your mobile is specifically designed for this use (and I have no idea whether such a device exists).

(That shows how much I know about mobiles. See below. :) )

As eric said, you shouldnt need the cd at all to configure the router, and should have been able to directly access it, Ive no idea why this made any difference either.

A router is a stand alone mini computer with its own processor and even some memory so you should be able to access direct over the lan from your PC using the following link http://192.168.1.254

>> Of course I could use that for my mobile??

If you mean use your adsl connection rather than 3G to access the internet... then yes you can... it can be used for phone and i-devices.   
I do this a lot as it can save a heck of a lot of data usage if you are downloading to or uploading stuff from your phone/i-device. 

I dont know what mobile device you have, but this should be easy to do..  I only mention the 'should' because some HTC devices seem to have problems  connecting via wi-fi.  HTC are aware of the issue, apparently some models have an upgrade available to correct this, but despite being up to date with firmware, I still see problems with some routers with my HTC Desire S.  Other phones/devices should be fine.

If you are worried about wifi security, then most routers can be configured to allow only that device to connect that you authorise.  It can take a wee bit longer to first set up, because you have to physically go into the router settings to allow that one device.. but it means that other devices cant connect without your permission first.

It would be interesting to see some line stats from the new router.

I am glad the line is working more relaibly now. The new router seems to be working and connecting first time. Not sure why I could not get it to work without the cd. Bizarre.

I have an HTC desire for a phone. I am not sure I should tempt fate and try setting it up for wifi.

I would love to upload stats for the Billion router. Any instructions on this?

Lots more things to play around with. Including the WiFI settings.

I wonder if you installed the old Voyager with a CD and it added some drivers and network settings that were confusing things, but have been reset by using the new router CD?

I'm assuming that the web interface is similar to the 8800N, in which case the main stats are obtained by clicking on Status --> ADSL Status. You should be able to copy and paste the details.

Or telnet into the router from a command line window:

telnet 192.168.1.254

(enter the router login name and password when asked (default values are name=admin, password=admin)

adsl info --show

Then pick out the upstream/downstream connection speeds, attenuation and noise margin from the data returned.

Finish by typing 'logout' to terminate the telnet session.

You may have a very valid point there HP!   :idea: 
Some of the old USB modem software could do exactly this.  In particular, the ST330 (frog) drivers were notorious for stopping routers from being able to connect properly until the old drivers had been removed.

About 5+ years ago this used to be a common problem when users were upgrading to their first router from the ST330's... but these days you seldom see them. .....  hmmmm  I wonder if there were some old USB modem drivers still on that PC.

It's a few years now since I upgraded anyone from a "frog" to a router but I always used to go round and "clear out" assorted bits and pieces from network-related configurations and settings. Always did it manually and can't now recall what, but if I sat down at one it would no doubt come back to me.  :graduate:

Hi
You have changed routers  yes ?. The stats display is different.
If that is the case then you are being Capped by your ISP.

Okay Vispa got back to me. That was quick.

They say BT capped my line at 6mb as it kept dropping. Probably cause i kept turning off the modem.

They have asked BT to reset my line. Will take 24 hours.  8)

I will be back in 24 hours with some line stats once they get it sorted.

Finally getting somewhere. :)

Excellent news.

Thats the fun bit for the ISP ;).  I did mention in one of my earlier posts that I suspect that it may be the 'silent' DLM cap because  6656 does seem to be a common figure set by the DLM, if it thinks a line is unstable.

Sometimes even the ISP isnt immediately aware that the line has been capped and a while they used to have real fun trying to convince BTw to reset the line.  Supplying your linestats to the ISP and stating that you now have a new router helps convince them that you kinda know whats going on.

My memory is rusty, and I'm sure someone will correct me if Im wrong/out of date, but the automated/queued resets generally tend to occur during the wee small hours.  So hopefully either tomorrow morning or the day after your line will resync at a much higher rate.

You may incur a bit of instability over the next few days, as your connection settles into the new best rate for your line.   I would leave the router connected during this period....  unless theres an obvious problem from the stats, and we will advise you the best time of day to reboot.

Could either be:-

1) ISP not yet advised by BTw of new speed and they need to adjust their figures accordingly.  ISP's are advised in batches daily so could be tomorrow before any ISP profiling is lifted.

2) New bRAS (http://www.kitz.co.uk/adsl/IPprofile.htm) not yet updated.

>> would firefox continually not responding lately be due to my broadband or poor browsing software??

TBH Ive found that FF is often clunky and slow and Ive been turning to chrome, which is a lot quicker.
However it could be your line..  again your linestats can tell us a lot about this..  we'd be looking at the type of errors reported from your router over a period of time.

The continual firefox not responding but recovering a few mins later has only started in last month or so? I have never really tried Chrome. I just removed all the google stuff from my pc and now you suggest i re add it.  :wall: :wall:

Let's see how my line stats settle over the next few days. I am leaving the modem  on 24/7 now.

Do you think this line would hold an infinity service?? Would it truly reach 40mb speeds?? I am jumping the gun a bit. They have delayed my FTC date to December 31st 2011.

Do you know why Plusnet can install FTC services so cheaply?? It seems companies not owned by BT charge nearly £100 just to install it.  :ouch:
Vispa are suggesting this is what BT Openreach charge circa £79+vat.

I think for now let's wait and see what speed this line settles at. :)

Okay Vispa have got back to me again. Their customer service is so quick!! Under 30-40 mins maybe??

Quote vispa email in bold.
BT wholesale do not advise us when the reset completes, nor do they advise us what the speed will be once completed, however, upon checking it just, it appears that the increase has completed. As you can see from your router stats (and I have confirmed this on BT systems) your downstream speed is now 16650 Kbps (16.5 Mbps)

When you ask 'have you adjusted your ISP settings accordingly', can you please elaborate on what you mean by 'ISP settings'?


Also, your upload is capped as you are on a residential product, if you would like a higher upload speed then you can choose one of our business packages which will remove the upload speed cap.


All fair enough really.

I did a speed test on the BT site and got these results around 21.15hrs today.  I need to do 2 more tests at different times. What is a good speed for a 20mb service??? I guess no one truly gets 20mb speeds.

 Download speedachieved during the test was - 7424 Kbps
 For your connection, the acceptable range of speeds is 4000-21000 Kbps.
 Additional Information:
 Your DSL Connection Rate :16650 Kbps(DOWN-STREAM), 443 Kbps(UP-STREAM)

I wondered about that but they are also £5 cheaper a month but I doubt they offer a fixed IP address or other services like website space. Let's see if the FTTC is actually ready for Dec 31. It has been delayed by 3 months already. I am not expecting openreach to rush to reach my flat. Perhaps vispa should offer 18 months contracts if it reduces installation fees. Then more might upgrade.  ;)

In terms of upgrading if an engineer replaced my BT socket cover would that make it already compatible with FTTC? I know they have to do a number of checks in the home and at the exchange.

@ HP - I have run that lil software package. Seemed quicker on the start. I wonder if the not responding browser is down to installed add ons. Need to keep playing with this. I did play with some settings a month or so back to fix an email issue.

>>> When you ask 'have you adjusted your ISP settings accordingly',

Many ISP's have their own profiles which they place on the account which matches the profile set by BTw.  Plusnet is one ISP who are very open that they do this. Im unsure if Vispa do or not.

>>> Also, your upload is capped as you are on a residential product,

Fair enough, if thats their product set. 
Many ISP's will give their customers the full 'upto' 1Mb upstream (which usually syncs @ around 832) when on adsl 2+ and dont cap it at 443.

>> IP Profile for your line is - 14690 Kbps

Thats looking good, it means the DLM is seeing you sync in the 16Mbps region...  and your actual through put speeds should be around 14Mbps.


>>> Download speedachieved during the test was - 7424 Kbps

Hmmmm....  thats still looking more like 8Mbps speeds to me.  :(
Obviously your speeds can vary during different times of the day, depending upon how busy the ISP pipes are.  Early morning is usually a good time to test.

It depends on which product (http://www.plus.net/support/broadband/products/IP_addresses_broadband.shtml) you get.  I used to have static IP and free CCGI webspace when I was with them... although I believe the freebie webspace may not be available now.

Saying that though I can recommend a very good web hosting company that will give you a free domain and web hosting from just £17pa.

I did try Plusnet online advisor. Yeah they do offer a fixed IP address. To be honest I am not sure I have ever used mine with Vispa. Could use it for a server or stuff I guess?? Need to look into what these are for. Gaming?? Servers?? hmmm.

The sync speed does look good but the speed is simply still not there for some reason. I am about 1.29 miles from my exchange by road. Who knows which end of the loop I am on.

Still got not sure why I am so slow. It could just be I have a weak line? Or I am secretly downloading stuff and I am not aware of it. Hmmmm.

From what I can see so far.. no its looking ok... but really need to see if any errors are being recorded. Due to the fact that you havent so far seen any speeds over 8Mb, im not yet ruling out a cap somewhere..  ISP contention could also be in there too.

>> I am secretly downloading stuff and I am not aware of it.

If I want to rule out that possibility I usually install the freebie Netmeter.
http://www.metal-machine.de/readerror/

then go to a site like
http://www.btopenworld.com/speedtest  and download the large 15Mb file ... and see what speed netmeter shows your throughput as.

When you do that test make sure that its only your PC thats connected to the router... and this will show you what your real-time speed coming into your network is.

Will try the other 2 things after work.

Did a BT speed test this am and got pretty much 8mb speed. Hmmmm.

Not sure how long that line has been up when you took those stats, but there are quite a lot of HEC errors and Errored seconds, which indicates that there is a possible slight problem on that line at times.   

This could be due to "normal SNRM" dipping in the evenings... but this could/will be why your connection seems sluggish and unresponsive at times.

That said..  I am not too worried about that just at present, because your line has just reset and the DLM will still be monitoring and its early days. 
You still appear to be on the default SNR Margin of 6dB and its not yet turned on interleaving.  Interleaving is normally one of the first steps that the DLM will activate to try and stabilise a line, I would not be too surprised if interleaving is switched on over the next few days if the HEC errors + ES + UAS continue.

The info gives us a little bit of a picture of what is happening on your line.. I must re-iterate at present Im not too concerned because your line may be one of those that perhaps needs a slightly higher SNRM to cope with normal day to day variations.  When you get things like SES's and UAS's then you are likely to see 'pauses' when you are doing things like browsing.  Theres a full explanation of what they mean here:- line stat errors (http://www.kitz.co.uk/adsl/linestats_errors.htm).  The DLM will at some point adjust accordingly to try and compensate.

If I were you though, I would be using something like routerstats (http://www.vwlowen.co.uk/internet/files.htm) to monitor the SNR on your line.  This graphs your SNRM over periods of times and provides a good snapshot of your line.  Its an invaluable tool for self diagnostic of adsl issues...  and helps show what the DLM will be seeing.

Welcome to the wonderful world of adsl... and just how geeky it can get!


----
btw..  the above is not related to you not appearing to be able to get over 8Mbps.  The indications are there, that at least some of the time you should be able to get throughput speeds of around 14Mbps.

>>> Who knows which end of the loop I am on.

The far end!   - Sorry Will couldnt resist that.  :-[



Cheers for that. lol

In terms of DSl there is clearly a lot for me to learn. I will have a look at that tool when I get a chance. Only just back from work. Knackered!!

I think we should allow the line a few more days to mature. :)

Oh my latest BT speed tech cam in at 8024mb speed? That seems almost too exact.

Reached a max of 1.43mb/s on net meter. That seems rubbish.

On a plus side the net reader seems to be at 0mbs when i am doing nothing.

Router stat still shows 6db! Hmmmm.

Double check that figure.  Check the options in NetMeter.  Ensure its set at kbps and NOT kB/Sec

1.43 MB/sec =  11.44Mbps = 11715 kbps

(1.43*8*1024)

4 options.

kibibyte (1kiB=1024bytes)
kilobyte (1 kb=1000 bits)
kibbit  (1 kibit=1024 bytes)
kilobit (1kb = 1000 bit)

Which one to choose on Net meter???

Hi

 kibibyte (1kiB=1024bytes)
kilobyte (1 kb=1000 bits) Bytes
kibbit  (1 kibit=1024 bytes)bits
kilobit (1kb = 1000 bit)
slightly wrong got your bits and bytes mixed up

you can use any as long as you understand that 8bits = 1 byte
Byte  is the normal report from download software ,Kilo or Meg  (windows update etc )

speed testers report in Bits  ,Kilo bits ,Mega bits

Unfortunately there seems to be no definite application of 1000 or 1024 bits for Kilo

Technically should be 1024 . But in real terms the difference is not important

So the BT 15 MB download is shown as 1.52mib on net meter. Now is that in megab bits ot bte or something else.  ???
