ADSL2+ upgrade woes - me too!

dgharwood · 07/05/2009, 18:15

I was upgraded to ADSl2. Had to wait for BT for ages as they had a backlog.
When finally got it, was getting around 11 Meg.

First got this:
Your DSL connection rate: 12295 kbps(DOWN-STREAM), 1144 kbps(UP-STREAM)
IP profile for your line is - 10000 kbps
Actual IP throughput achieved during the test was - 4941 kbps

Then got this (the next day) - with a lower profile:
Test1 comprises of Best Effort Test: -provides background information.
Your DSL connection rate: 10747 kbps(DOWN-STREAM), 1179 kbps(UP-STREAM)
IP profile for your line is - 9000 kbps
Actual IP throughput achieved during the test was - 6462 kbps

And now am syncing at 6656 kbps - with low low speeds. This is so silly. ADSL was better! A fault was raised with BT on 1st May and now nearly a week in and BT have not done anything. ADSL24 are chasing up BT, but this is such poor service from BT.

I have now been asked to do 2 further line tests for the fault to be raised with BT again. I don't really understand why I have got to do this when a fault was originally identified.

Will keep my fingers crossed that BT sort this out but not holding my breath!

Weird... I have the exact same issue...Also synced at a high rate initially when moved to 2+ then went down to the below which is EXACTLY the same rate as you are getting (seems too much of a random rate to be a coincidence)
If you look at my screencap from DMT you can see that the actual attainable rate is 10068kbps (next to RCO) which means somehow its not being allowed to sync at its max rate - its only running at 66% of its capability!
Upload seems to be OK as that is at 99%
Somehow the sync rate is being held artificially low ...
...and I wouldn't hold my breath for BT to fix it...they have their hands full trying to sort out the 2Meg cap that their shoddy new ADSL2+ equipment is inflicting on loads of other subscribers.

Thanks for the info - I will try the same test and post results tomorrow.

My previous experience of getitng BT Wholesale to sort through problems has been really bad, and this is even after complaining to various difrerent complaint sections and trying to take it further. I found that one department passed it to the other and then as the ISP is ADSL24/Entanet, they just took their time.

This time, I will not let this lie as everyone seems just to have to accept that: Oh its BT, which is our main infrastructure.

On their BT Business Site, they actually offer advice on looking after the customer!!! I am sure this is a Joke!

Not sure if I can use DMT on my router - I have a DG834G running version 5 of the firmware - will play around tomorrow.

check this forum out... should help... seems it works with V4 & V5 (though there is a entry in the forum about entering an additional line *???*)

all versions of DMT from here... http://dmt.mhilfe.de/

im having similar issues, these are my current stats

Test1 comprises of Best Effort Test: -provides background information.
Your DSL connection rate: 13484 kbps(DOWN-STREAM), 444 kbps(UP-STREAM)
IP profile for your line is - 10000 kbps
Actual IP throughput achieved during the test was - 5728 kbps

My upstream keeps changing between 447 and 888 kbps.

But the main thing is i have never managed above 6500 ish kbps downstream at any time of the day on multiple days.

Thanks. I managed to set the router to debug mode and can telnet to it. DMT is reporting 'Cannot identify modem type'. I think because of the chipset it may not be supported. I will just have to wait for BT to do something!

I think it would be useful for ADSl24 to provide a general update on this issue as it seems quite a few users are experiencing the same problems.

Add me to the list of people with the downstream sync capped at 6656kbps. I first reported the fault to ADSL24 on 15th March yet here I am still with the exact same issue. I've come here in the hope that pooling data and experiences might get something done about it.

At first ADSL24 got BT to reset the target margin and remove the cap but shortly afterwards it went up the creek again, I've been through the sync speed dropping process three times now and each time it follows the same pattern.

Over the space of a few days the target SNR margin goes from 6dB -> 9dB -> 12dB -> 15dB and then finally a hard cap of 6656kbps is applied so that the router will not sync above that speed no matter what the SNR margin is. During this time the router doesn't lose sync once aside from the forced resyncs at the exchange end to set the new margin/cap.

It must be clear to anyone with half a clue about BT's DLM system that it is at fault here and applying measures to stabilise a line that is already perfectly stable. This leads me to believe that despite ADSL24's best efforts to raise this with BT it either isn't getting far enough up the support chain that it gets seen by some who understands what is going on or it is and BT can't be bothered/don't know how to fix it.

At first I thought it was a problem specifically with my line/exchange but clearly that it not the case now that other people have noticed the same thing. It would be interesting to know just how many people are affected by this.

The latest from ADSL24 on my support ticket is that BT are requesting yet another Speedtest result (this would be the 4th) and that if the speed is still low they will send an engineer out with the usual nonsense that I will get charged if they find no fault.

Now since the line gets a stable full 8128kbps sync on ADSL1 I find it incredibly hard to believe that there is any issue with the line itself. I am not going to get a engineer out and get charged for a fault that is clearly at the exchange end with the WBC kit (or more specifically the DLM software I suspect).

It's clearly not a router issue either as dgharwood has a different router to me and so must macanix as mine doesn't support DMT, it's the 2Wire 2700HGV (aka BT Business Hub). Just waiting for when BT try to pin this on my router, a BT branded product!

Reines · 08/05/2009, 16:03

I haven't been upgraded yet (submit request last week, it's due to go through on monday now, nice 48 hours...).

However since the exchange was upgraded, I've gone from syncing at 8128 (never dropped below 8128) to syncing at under 7k somewhere (6752 at the moment). I'm not sure if it's related to the issues you people are having since I'm not actually on ADSL2 yet, though since it happened as soon as the exchange was upgraded it seems likely.

khemical · 08/05/2009, 16:16

That's interesting Reines, your case appears slightly different to mine but may well be down to the same underlying issue so will be interesting to see what happens when you do get on to ADSL2+.

When Enta screwed up and set my line back to ADSL from ADSL2+ for a week the increasing SNR margin/capping issue went away. As soon as I was back on ADSL2+ the issue returned. So for my line at least the problem appears to be with ADSL2+ specifically, not the WBC based connection in general.
