44Kbps from 20MB service

The advisor arranged for a new Thomson modem to be sent out. This has now been up and running for 3 days (with a new filter) but we are still capped at 135Kbps. One advisor said that the modem stopped the dropouts but another one said they were still happening. I am running regular speed tests and the last one showed that I am getting a download speed of 44Kbps. This is worse than useless, as it takes around 30 seconds to load most web pages.
I have little confidence in Plusnet support, because the advisors keep contradicting each other. Having read through some of the threads on here, I am concerned that this could take months to resolve. Can anyone here help, and if so, what other information can I provide? Thanks.

If you are still using the Thomson you get them from here http://192.168.1.254/cgi/b/dsl/dt/?ce=1&be=0&l0=1&l1=0

I'm just running a quick line test to see what speeds your router is connecting to the exchange at now.

That's the second banded profile in the last day or so that seems to have been applied incorrectly by the DLM.
Superusers are not staff, but they do have a direct line of communication into the business in order to raise issues, concerns and feedback from the community.

Quote from: Oldjim The stats from your router - speeds, attenuation and noise margin.

Thanks for that. Here are the router stats:
Link Information
Uptime: 0 days, 9:43:09
DSL Type: G.992.5 annex A
Bandwidth (Up/Down) [kbps/kbps]: 444 / 283
Data Transferred (Sent/Received) [kB/kB]: 0.00 / 0.00
Output Power (Up/Down) [dBm]: 12.0 / 0.0
Line Attenuation (Up/Down) [dB]: 14.5 / 29.5
SN Margin (Up/Down) [dB]: 29.0 / 22.0
Vendor ID (Local/Remote): TMMB / IFTN
Loss of Framing (Local/Remote): 33 / 0
Loss of Signal (Local/Remote): 3 / 0
Loss of Power (Local/Remote): 0 / 0
Loss of Link (Remote): 0
Error Seconds (Local/Remote): 3 / 0
FEC Errors (Up/Down): 0 / 32,341
CRC Errors (Up/Down): 0 / 0
HEC Errors (Up/Down): 0 / 0
And the BT speed test says:
Download speed achieved during the test was - 52 Kbps
For your connection, the acceptable range of speeds is 50-250 Kbps.
Additional Information:
Your DSL Connection Rate :283 Kbps(DOWN-STREAM), 444 Kbps(UP-STREAM)
IP Profile for your line is - 135 Kbps
The throughput of Best Efforts (BE) classes achieved during the test is - 9.62:25.0:65.38 (SBE:NBE:PBE)
These figures represent the ratio while sententiously passing Sub BE, Normal BE and Priority BE marked traffic.

There's nowhere in there that shows anything like the 10/hr disconnections that should be needed for the DLM to register a 'flapping line'.
As far as I can ascertain, immediate banding should ONLY be applied to a 'flapping line' , errors should cause the DLM to apply interleaving and then raise the SNR target in 3db steps to 15db before going to a banded profile.
Edit: Those stats are 'orrible. Can you post a set of stats using the test socket ?

Quote from: Chris One of the faults agents has requested that this is removed and we're awaiting confirmation of that. I'll speak to the faults guys and ask them to chase this again.
Thanks very much for your input, Chris. I just had a call from Phil at Plusnet support, who tells me he has asked BT to remove the banded profile and that we should see an improvement within 24 hours. Now we are getting somewhere.
The only thing that's confusing me now is that another advisor told me on Wednesday that he had asked for the banding to be removed - he even wrote it on the ticket. Hmmmm
I'm certainly glad I found this site.

Are they? I'll do my best if you could you tell me where the test socket is and how I use it.

When the banded profile is removed your sync speed should increase significantly, hopefully well above 10000kbps but that depends on whether the target noise margin has been raised due to the problem. However note that it might take a couple of days for the IP Profile to increase and until it does speed-test results will not change. If the target noise margin has been raised it should automatically reduce when the DLM sees line stability is now good.

I can't get the computer near the test socket without an awful lot of upheaval - it's two floors away. You might have spotted a weakness in the setup here. The modem is connected to a BT socket that is about 100 feet away from the master socket, with a couple of phone sockets in between. It's a mess, but fixing it would require an expensive visit from a BT engineer - and it wasn't really a problem with ADSL1. I suspect we might have to bite the bullet now though. What do you think?
Here's an updated set of stats. They're from the same socket, I'm afraid, but some of the numbers are quite different.

If you enter your phone number and postcode into Kitz's adsl checker here, how far does it say you are from the exchange (direct and by road)? And what 21CN WBC speed is given in the BT Line Speed estimation table?

I am 1.13km direct and 1.61km by road. It says 'Not Available' against the 21CN WBC speed estimation.
