Can any one shed any light on this for me please, I've been regraded to adsl2+, I'm only getting around 6.5Mbps at the moment even though I'm currently syncing at 16,527 Kbps, the BT Speedtest has my IP Profile as 14.58 Mbps. Is the slow speed just a process of the 10 day thing (ie am i being impatient) or am i missing something?

Your SNR is currently 11dB so this will make the sync rate a little lower. Are you using any extension cables/sockets? Do you have a test socket you can plug into?

If using an extension is causing extra errors or disconnects it could take many days if not weeks for the improvement given by using the test socket to show through in speed test results.
When on ADSL1 you were syncing at full speed so there would have been plenty of spare margin and the extension lead would not have been a factor. Now it's attempting to run at higher speeds which will give a lower margin the extension could be significant.

I didnt run a speedtest from the test socket, I just noted that the sync speed and noise margin were unchanged.
Cheers

If you leave it in the test socket for a few days and it stays stable with no disconnections you could then ask PN (via these forums) to reset the line which would set the target back to normal and give you higher speed. If that stayed stable (still using the test socket) for a week or so you could then try the extension again to see if it caused the speed to drop.

Thanks mate I see where you are coming from, I'd do that now, I'll run it from the test socket for a few days, thanks again for your advice, much appreciated.

The target SNR is 12dB at the moment, so if it hasn't improved in the test socket, once your 10 days are up I can request it reset back to 6dB.
