How long do you think i need to wait before it restores my faster connection, which was stable until i started pratting around with the router. I must have bounced it perhaps 10 times in the past couple of weeks.

It seems to be complete mystery, with many web pages devoted to the subject ... I read somewhere, that your ISP might be able to get OpenReach to reset it. (But my understanding, is that it's not caused by multiple router reboots, but by multiple errors on the line. Also, it seems to have more of an effect on latency, than speed).

Interestingly, my 2860n was rebooted many, many times last week, thanks to Western Power and their archaic wiring in North Devon (power off for 10 seconds, back on for 10 seconds ... repeated for 2 hours - until it went off completely for 8 hours). The 2860's 'reported SNR' dropped instantly and took a week to recover, but the sync. speed was larger unchanged. I don't believe the line was ever set to "Interleaved" - and it definitely isn't now.

That's what I thought about errors, but having read multiple fora like Kitz for example, I don't think that's solely the reason. Users there post that interleaving kicked in after multiple resets. My tentative conclusion is that it depends on how DSLAM equipment is set at a particular exchange and your profile. My line is noisy but I'm on fastpath and that's despite several restarts in the past.

In response to what can be done: you could try asking your ISP to reset the line or wait until you have a period of stability - some users report a few weeks - and should be back to fastpath.
