speed problem

[#1]

Looking for a bit of advice and possibly help from Plusnet staff.
First the background, ever since joining Plusnet my download speed has been about 4Mb which with an attenuation of about 30db I realise is quite low. I have accepted this as I think I knew the answer, following some building work my telephone extensions, including where the router is connected, were wired in non telephone cable (alarm!)
This week I decided to improve matters and installed an ADSL nation faceplate to the master socket, moved the router to that point and used homeplugs to get to the PC. The results are not good.
I will post the router stats at the bottom of this post, but it is syncing at 3023 Kbs which has not changed in the 2 days it has been in sync, the SNR is 29.5 which I realise is having some effect but using a corded phone on a quiet test reveals no noise at all.
Logging in to the member centre shows my line speed at 2.6Mb.
Running the BT speed tester gives a line speed of 2.5 and an IP profile of 2.66 with a max achievable of 4Mb.
Unfortunately before installing the face plate I did not check the router stats so it is quite possible that it was already syncing round about the 3Mb.
I would welcome any thoughts and help.

I'd suspect a 'Banded Profile': http://www.plus.net/support/broadband/speed_guide/broadband_terminology.shtml#bandedProfiles

Hi plustrev,
I've placed a SNR reset on your line as your speeds are currently restricted due to a bout of disconnections recently. Your line does now however appear to be very stable so the SNR reset should help.
This usually takes around four hours to take effect, let me know how you go.

Hi Chris, thanks for that.
It has already taken effect, my connection just dropped out and when reconnected it is syncing at about 14000Kb

Afraid I still need a bit of help on this.
Since the SNR reset on Friday I have been synching at more than 14Mb (currently more than 15Mb) and the BT speedtester shows a profile of 13Mb but the download speed is only 2.5Mb.
I think perhaps the Plusnet profile is stuck on 2.6?  Thanks for any help.
1. Best Effort Test:  -provides background information.
Download  Speed
2.49 Mbps
 
0 Mbps 21 Mbps
Max Achievable Speed
Download speedachieved during the test was - 2.49 Mbps
For your connection, the acceptable range of speeds is 4 Mbps-21 Mbps.
IP Profile for your line is - 13.68 Mbps
2. Upstream Test:  -provides background information.
Upload Speed
0.84 Mbps
 
0 Mbps 0.83 Mbps
Max Achievable Speed
Upload speed achieved during the test was - 0.84Mbps
Additional Information:
Upstream Rate IP profile on your line is - 0.83 Mbps

This test was not conclusive and further testing is required.This might be useful for your Broadband Service Provider to investigate the fault.

Your speed profile is now matching your IP profile, give that another try.

Hi Chris, Yes that has sorted it.
Router Synching at 15.505, BT Profile 13.68, D/L speed 12.91.
Thanks
