My ADSL Max Premium connection is usually very stable (weeks between drops), and I usually sync at 8128Kbps down and 832Kbps up, with a profile of 7.15Mbps (as would be expected).
The router gives an "attainable" upload rate of 1.2Mbps which would be the case for ADSL2+, but obviously not for ADSL Max Premium.
This morning the router reconnected and the upload sync is now only 640Kbps, with an "attainable" rate of 752Kbps. The profile is still 7.15Mbps.
The SNR for the upload has dropped to 6dB (usually 9dB at 832Kbps), while the download is still at 11dB.
There's no obvious difference in the tones. and there has been 1 upload FEC error in the past couple of hours (that is unusually high for my line, but is still only 1!).
I'm aware that the profile is adaptive, but it hasn't changed - and does it affect uploads anyway?
Any suggestions on how to recover the upload speed (resyncing hasn't helped)?
