Sync speed halved after BT line fault

I've had a pretty much faultless adsl2+ connection with plusnet... until a fault occurred with my line on the 'BT Network' last week. After receiving appalling service from BT, my line is now fixed. However, prior to the fault I was syncing around 8500 up, but now it's not getting any higher than 4500 up. One thing I've noticed that is different now is Fast Path connection is on; this used to be interleaved.
Would the loss of interleaving make such a big difference? If so would it be possible to switch it back on?
Thanks for listening.

You can often tell which it is by looking at the noise margin.
If it is much greater than 15dB then it is almost certainly a capped profile

Is this something that will improve with time?

Just let us know if you want us to invoke an SNR reset. This will restart line training, however given the figures you mention it sounds to me like your upstream may be capped. I'll go away and check this and report back ASAP.
Adam.
EDIT: on second thoughts could you drop me your username on a PM? I've not been able to trace your account yet.

Does the never changing sync rate indicate that some kind of banding is still being applied?

Yes there's now a 3-6mb profile on your connection, I'm going to speak with one of my colleagues on the faults team for advice on getting this removed so I'll keep you posted.

I notice today that my snr has gone back down to 5.1 (which is nice), but my downstream sync is still never changing from 6656 kbits/s. Is there anything I can do to help remove the 3-6mb profile?
Cheers.

My BT profile is currently 7150k, but pn is still showing 5500, can this be increased to it's previous value of 9000?
Many thanks,
Carl.
