ADSL2+ updgrade

gwidnet · Jan 09, 2011, 16:05:50

Hi everyone, I've finally bitten the bullet and applied for the ADLS2+ upgrade. Scheduled to happen Wednesday. My rock steady connection (apart from the times when it hasn't been working) of 5700 wotsibits is now lagging at a decidedly slower 1888 wotsibits. Does anyone know if this is the first part of the ..ahem.. upgrade process, and please tell me that I haven't made a terrible mistake.

Glyn,

I would think it is just a coincidence, but if you can post your router stats and a BT Speedtest, then Rik, Lance, Steve or someone else, will be able to help you further.

gwidnet · Jan 09, 2011, 16:18:24

Hey Glenn, no worries I won't trouble anyone at the moment, as the upgrade is happening on wednesday anyway, so I hope it'll straighten out after that. It is a strange coincidence though after 3 or so years of being fine, it has a slight wobble.
I have my fingers crossed for wednesday though

Glenn · Jan 09, 2011, 16:19:46

Steve · Jan 09, 2011, 16:33:41

If the wobble is due to 'noise' it may well get worse on adsl2+ as that's much more sensitive

gwidnet · Jan 09, 2011, 16:42:25

How noisy should it be?

ADSL Link    Downstream Upstream
Connection Speed    1888 kbps    448 kbps
Line Attenuation    36.0 db    19.0 db
Noise Margin    15.4 db    20.0 db

And BT speedtester is being mean as well

The Performance Tester is currently unable to run a speed test for your broadband connection. Please try again shortly, however if this problem persists, raise the issue with your service provider.

Steve · Jan 09, 2011, 16:58:24

Somethings wrong somewhere, the default downstream noise margin on adsl is 6 , yours has been raised in 3 db increment to 15, This is done to stabilise your connection unfortunately with this down goes your sync and throughput. You need to try to find the source of this noise, if it's your side of the master socket you can usually cure it. Culprits are ring wire, faulty filters , long extensions,sky boxes and failing routers.

If have a look at the help FAQ's it's explained in detail

Ah thanks Steve, I like the sound of a failing router best - anything else is more difficult to find - the router has been a bit prone to losing the odd wireless connection sometimes - we do have about 7 devices connected.
My router is a dgn2000n what is currently thought to be a good router?

Rik · Jan 09, 2011, 17:26:29

There's no easy answer, unfortunately, the best router is the one which works best for you. I'd be inclined to pick up a 2-Wire 2700 from eBay, should be <£20 including shipping, in the first place.

For those of us with noisy lines, these have often produced much better stability.

gwidnet · Jan 09, 2011, 17:51:43

Ok I thought I'd do a bit of investigating. The only thing which has changed recently was the addition of a sony blu ray player with an ethernet connection to the router. As soon as I unplugged the ethernet cable from the router, the Noise dropped from 15.1 and is now at 8.0. This happened within 5 seconds. Yeeeeeeeehaaaaaaaa

Edit: still connected at only 1856 but I'm more hopeful, noise now 7.9

Rik · Jan 09, 2011, 17:55:03

If only every solution was that simple. Re-boot the router in the morning to get your speed back.

gwidnet · Jan 09, 2011, 18:01:08

I'm glad I identified the source of the problem before the upgrade on Wednesday or we would all have been going round in circles for hours!

What about my blu ray player? I may try a different ethernet cable later or perhaps the router is a bit faulty as well?

Rik · Jan 09, 2011, 18:04:51

It's something you can only solve by elimination, cable, router, try Bluray player on someone else's router etc.

Steve · Jan 09, 2011, 18:17:28

How is the blu ray player inducing noise into the router , it has to be via the ethernet cable surely? Can you isolate this with an ethernet cable with the knobbly plastic bits on.

You know what I mean

Glenn · Jan 09, 2011, 18:20:45

It could be a poorly screened connection inside the Bluray player.

gwidnet · Jan 09, 2011, 18:21:17

Hi Steve, yes it was one with the grey plastic contraptions on, and I swapped it for an ordinary ethernet (short) cable and the noise went straight up to 15 again (currently sitting happily at 7.3)

gwidnet · Jan 09, 2011, 18:23:35

Glenn yes for info its a Sony BDPS370. I'll have a root around on avforums to see if anyone has come across this before.

Ted · Jan 09, 2011, 19:43:42

Call me a Neo-Luddite, but why is the Blu ray player connected to the internet?

Rik · Jan 09, 2011, 19:45:55

A lot of discs will d/l extra information from the web, Ted.

gwidnet · Jan 09, 2011, 19:47:21

Oh no, noise is now up to 15.1 again and sync speed is 896. No blu ray connected.

Aaaaaaaaaaaaarrrrrrrrgh

I'm going for a dying router - I've had a rock steady connection for years.

Its because you can watch things streaming on the net, like iplayer and lovefilm to name but two.

It's possible, but given your margin seemed to adjust so quickly, I wonder if something else is involved here. Does the router log should multiple resyncs?

That's just the firewall working. Your line seems reasonably stable, tbh.

Ok I thought I'd do a bit of investigating. The only thing which has changed recently was the addition of a sony blu ray player with an ethernet connection to the router. As soon as I unplugged the ethernet cable from the router, the Noise dropped from 15.1 and is now at 8.0. This happened within 5 seconds. Yeeeeeeeehaaaaaaaa

Edit: still connected at only 1856 but I'm more hopeful, noise now 7.9

Hang on a mo. That is nothing to celebrate. It is ouch, not yeeehaaa :-(

The noise did NOT drop. The noise MARGIN dropped with no increase in sync speed. That means that the noise increased.

If you unplug things without resyncing or rebooting the router, you want the reported noise margin to increase. A good result would have been to unplug the bluray and see the noise margin increase to 24dB or 25dB.

In the situation where noise margin has dropped from 15.x to 8.x without a resync, that means your noise has INCREASED by 7dB. Then if you resync, accidentally or deliberately, your sync will drop to a level such that your target noise margin of 15dB can be maintained. That is why you resynced at 15.1dB but only 896 kbps.

To summarise:
Make any change without a resync and you want your noise margin to INCREASE.
If you resync immediately after a drop in noise margin, you will get a lower sync speed.
If you resync after a stable increase in noise margin, you should get a higher sync speed.
After a resync, you want a higher sync speed and a lower noise margin.

Experts correct me if any of this is wrong. I say you still have an unsolved noise problem. I am not competent to diagnose why removing the bluray ethernet cable from the router decreased the noise margin. But it should not have happened.

Rik · Jan 10, 2011, 15:28:50

Good point, Dill. I must admit I've been more than a little pre-occupied with getting the forum repairs sorted over the past week, and didn't read the post as I should have done.

armadillo · Jan 10, 2011, 17:26:46

Thanks for confirming my understanding, Rik. It looked odd to me to see a whole little sequence of posts apparently rejoicing in the noise margin going the wrong way

Rik · Jan 10, 2011, 17:28:44

We've had a fraught few days, Dill.

Oh!
As an update no blu-ray, this is the current state of play

ADSL Link   Downstream   Upstream
Connection Speed   1888 kbps   448 kbps
Line Attenuation   37.0 db   19.0 db
Noise Margin   14.9 db   18.0 db

I saw on another forum that if you wiggle the phone lead and the noise changes it could be a faulty lead, so my next plan is to try a new phone cable.

I'm just about to resync (not done since last night) and see what happens

Edit: Resynced at 1888 again
Edit again: If the noise increased immediately I disconnected the blu ray, only to go up after an unknown length of time ? mins then is it likely it points to a faulty router - having made no other changes to the filters/ring/sockets etc? The house is only 4 years old, so the circuitry is quite new, and I have disconnected the sky box. There is only one other telephone connected and I have disconnected that also.

Rik · Jan 10, 2011, 18:27:00

I don't know that it point to a faulty router, it could be emissions from the bluray player. Could you try it on someone else's router?

gwidnet · Jan 10, 2011, 18:36:30

I think I have eliminated the blu ray - it's not even on now.

I have a plan

I'm going to stop worrying about it for a couple of days, see what happens after the upgrade on wednesday and take it from there. I do have a spare router at work I could half inch for a day or two which I will try after the upgrade depending on speed.

As I see it, my connection has been perfect for about 3 years at about 5700 ish. I'd falsely fingered the blu ray (apologies blu ray), nothing else has changed, everything else is disconnected, so it's either my router/cable or a problem with the line (God forbid)

Rik · Jan 10, 2011, 18:38:39

The latter may be cured by the upgrade, as it entails a physical wiring change at the exchange.

esh · Jan 11, 2011, 12:10:20

All these DSL2 woes make me nervous for the scheduled exchange tweaking next month here.

Rik · Jan 11, 2011, 12:16:01

The thing to remember, esh, is we only hear of the problems. For me, I went from a 2-2.5M ADSL line to a 3.5-4M ADSL2+ line, and I have a very long line, 57db on ADSL, 61db on ADSL2+. The line is stable, and I'm able to run at a target NM of 6db, rather than the 9db on ADSL.

gwidnet · Jan 12, 2011, 14:51:47

I suspect you are interested to know what happened after the upgrade.

This is the current state of play

ADSL Link   Downstream   Upstream
Connection Speed   935 kbps   1075 kbps
Line Attenuation   35.5 db   14.9 db
Noise Margin   15.3 db   7.1 db

Superfast upstream, not so fast downstream.

Should I give it a time to acclimatise or source another router?

Steve · Jan 12, 2011, 15:01:12

Sadly I'm not surprised. Having looked at the FAQs mentioned earlier in this thread,can you confirm what actions if any you've tried to source the noise that's effecting your line.

gwidnet · Jan 12, 2011, 15:10:30

Hi Steve, I've disconnected all other telephone devices, including the sky box and home phone. The blu ray has been off for a few days. I have connected the router to the master socket which comes into the house in the garage. I've tried connecting the router to the phone line with a different filter.

Glyn

Edit: to recap, the only time the Noise fell quickly from 15 ish to 7 ish was just after I had disconnected the blu ray from the router

Steve · Jan 12, 2011, 16:19:28

If you've got the modern BT master socket,you'll find a test socket behind the face plate, can you connect the router directly to this? You'll need a filter if you wish to connect the phone as well. Using the test socket disconnects the house's internal phone wiring and we're looking for an increase in the noise margin for the same sync or an increase in downstream sync with or without a change in margin.

gwidnet · Jan 12, 2011, 17:46:45

Ok a proper yeeeeeeehaaaaaaa

One new router later (a cisco WAG320N)... I'm now have downstream rate 6555, upstream rate 1075.

I'm not sure where to find the noise levels on this new router - I've looked around can't find it anywhere, but I'm not too fussed. My connection is faster than before (was about 5700 ish), more download capacity, and when I get brave enough I'll whack my blu ray on again.

I am grateful for all the help I've had on here, you guys really are great.

I know I should be grateful my connection is back up to where it always has been (and better) - and I am grateful, ....... but is there a chance it may get faster still?

Rik · Jan 12, 2011, 17:48:06

There's a good chance it will, Glyn, if your line stays stable.

gwidnet · Jan 12, 2011, 20:00:47

Just out of interest and if it is of any help, I found the router stats at this address from another forum

http://www.kitz.co.uk/adsl/frogstats.php#54

and for my new router

As you see my noise is unchanged. Will my noise value fall as my line is more stable and be reduced in 3dB increments down to the usual 6dB?
What I reckon was happening was that my router was getting more dodgy by the day and the nose margin was being increased by the great god BT to try to keep my flagging router going.
It's quite interesting this stuff really isn't it?

Steve · Jan 12, 2011, 20:11:39

Fingers crossed and see how it goes over the training period.

Rik · Jan 13, 2011, 10:10:29

Theoretically, Glyn, your noise margin will reduce in 3db increments for every two weeks you maintain a stable connection until you reach 6db (sometimes 3db with ADSL2+) or the line becomes unstable again. However, with a bit of luck your new training period will, as Steve suggests, sort it out more quickly.

gwidnet · Jan 15, 2011, 10:02:15

Another update form me, I think things are going ok. My noise margin has reduced as you predicted Rik to 12 now.

Here are my current stats

--- DSL Information ---
DSL Driver Version: AnnexA version - A2pB023k.d21d
DSL VPI/VCI: 0/38
DSL Status: Showtime
DSL Mode: ADSL2+
DSL Channel:
DSL Upstream Rate: 1099 Kbps
DSL Downstream Rate: 7968 Kbps

Down up
DSL Noise Margin: 11.9 dB 6.5 dB
DSL Attenuation: 39.0 dB 14.9 dB
DSL Transmit Power: 0.0 dBm 12.4 dBm

My sync has improved a bit more, but my IP profile is still set on 750 with the BT speedtester, so still quite slow speeds.

Am I right in thinking it just needs more time and it's too early to be thinking about a stuck IP profile?

Rik · Jan 15, 2011, 10:31:40

How many days is it, Glyn?

gwidnet · Jan 15, 2011, 10:34:26

Rik, it was wednesday afternoon when I got my new router

Rik · Jan 15, 2011, 10:35:00

Give it till Monday, then.

gwidnet · Jan 15, 2011, 10:36:43

Ok will do thanks Rik

gwidnet · Jan 17, 2011, 19:28:17

Here's my update

--- DSL Information ---
DSL Driver Version: AnnexA version - A2pB023k.d21d
DSL VPI/VCI: 0/38
DSL Status: Showtime
DSL Mode: ADSL2+
DSL Channel:
DSL Upstream Rate: 1183 Kbps
DSL Downstream Rate: 7571 Kbps

Down up
DSL Noise Margin: 11.7 dB 5.7 dB
DSL Attenuation: 39.5 dB 15.2 dB
DSL Transmit Power: 0.0 dBm 12.8 dBm

I now have an IP profile of 5500 according to BT speedtester, reflected in my speeds.

It's all good now - should I just let the SNR improve on its own or should I disconnect and re connect occasionally?

Steve · Jan 17, 2011, 20:12:25

I would leave it connected, it should with adsl2+ sort itself out with after a period of continuous connection.

gwidnet · Jan 18, 2011, 07:12:08

Cheers Steve, will do

gwidnet · Apr 12, 2011, 18:51:48

Hi again since I last posted my noise margin has steadily increased so my line stats are thus

endor: Linksys
ModelName: WAG320N
Firmware Version: 1.00.12 , 2010-03-22T10:51:43
Boot Version: 1.06
Hardware Version: 0.01

--- DSL Information ---
DSL Driver Version: AnnexA version - A2pB023k.d21d
DSL VPI/VCI: 0/38
DSL Status: Showtime
DSL Mode: ADSL2+
DSL Channel:
DSL Upstream Rate: 1087 Kbps
DSL Downstream Rate: 3072 Kbps

Down up
DSL Noise Margin: 26.4 dB 9.3 dB
DSL Attenuation: 40.0 dB 19.5 dB
DSL Transmit Power: 0.0 dBm 12.4 dBm

Should I be concerned that my DSL transmit power is always 0?

Thanks

Glyn

Steve · Apr 12, 2011, 19:40:01

You've got a banded adsl2+ profile i.e max downstream sync limited to 3072 this is instituted by BT line management on noisy, unstable or lines with high error counts. Support can get this lifted although best to see if the cause can be cured.

gwidnet · May 29, 2011, 21:03:17

Me again!

Just an update to try to help anyone else with similar issues.

This is my current connection

--- DSL Information ---
DSL Driver Version: AnnexA version - A2pB023k.d21d
DSL VPI/VCI: 0/38
DSL Status: Showtime
DSL Mode: ADSL2+
DSL Channel:
DSL Upstream Rate: 1183 Kbps
DSL Downstream Rate: 8602 Kbps

Down up
DSL Noise Margin: 8.9 dB 5.6 dB
DSL Attenuation: 39.5 dB 19.3 dB
DSL Transmit Power: 0.0 dBm 12.4 dBm

Eventually my high noise margin was due to the router being sited behind the tv with all the cables causing interference. I put the router in a nice quiet spot and the connection has been excellent since. You may remember it all started when I connected it to the blu ray player and I thought that was the problem, but it was just the location. I plan to get a couple of homeplugs to connect it up now.

Anyway thanks for all the help and suggestions - just goes to show that all those nasty tv/skybox/av receiver wires can really mess up an adsl2+ connection

Steve · May 29, 2011, 21:22:13

Thanks for the feedback
