Drop in speed after upgrade

[#1]

I also have an ongoing question number ID: 31410127 if thats of any help.

[#2]

Have you added information to the ticket about the firmware update and the subsequent stability?

[#3]

yes siree!

[#4]

I'll reply to your ticket and request the SNR reset shortly.
In fact, as it's a 21CN line it's really not as easy as that just to request an SNR reset. I'll see what I can do.

[#5]

We can't do an SNR reset on a 21CN line, guys. It's ADSL1 only. I'll have a check for any banded profiles, which might be affecting things, but we can't restart the training period. I'll see what we can do re the banded profile and post back.

[#6]

ok cheers guys,
Thanks for all the prompt replies, much appreciated!

[#7]

Is it possible to set the SNR on your router? I'm on ADSL2+ and have managed to change my SNR down from ~15 to ~7 using the DMT tool. Previously used telnet to do this but DMT is much more convenient.

im in the  process of doing the 3 speed tests throughout the day as requested by the very helpful staff on the ticket system!
Was interested to know what the next steps would be after these tests?
If its of any interest heres the first test results

Test1 comprises of Best Effort Test: -provides background information.
Download Speed
2883 Kbps

0 Kbps 7150 Kbps
Max Achievable Speed
Download speedachieved during the test was - 2883 Kbps
For your connection, the acceptable range of speedsis 600-7150 Kbps.
Additional Information:
Your DSL Connection Rate :4539 Kbps(DOWN-STREAM), 440 Kbps(UP-STREAM)
IP Profile for your line is - 3000 Kbps
The throughput of Best Efforts (BE) classes achieved during the test is - 14.43:25.63:59.94 (SBE:NBE:PBE)
These figures represent the ratio while sententiously passing Sub BE, Normal BE and Priority BE marked traffic.
The results of this test will vary depending on the way your ISP has decided to use these traffic classes.
If you wish to discuss these results please contact your ISP.
If you are experiencing problems with specific applications, servers or websites please contact your ISP for assistance.
Your test has completed please close this window to exit the performance tester.
Please visit FAQ section if you are unable To understand the test results.

A downstream sync of 4539 is very close to the upper limit of one of the banded profiles - see http://community.plus.net/forum/index.php/topic,80204.0.html for more details. I reckon you might be banded, but we'll see what Matt says.

So surely (forgive me if i sound stupid) there are 3 modes in which the 21cn network works. Banded profiles being the one that it looks like im on. Could plusnet not just change the mode i.e to tagert snr ratio 
Way outtta my league on this one

[#11]

Im being told now that the issue (31410127) is being raised to the correct team for actiioning.
Does anyone know what this actioning would be/ If it will fix my speeds?

[#12]
