BT have DLM which automatically controls line paremeters to maintain stability, FTTC is still subject to things like noise interference so BT have kept DLM on.

When they believe the line to be unstable either from excessive CRC/FEC errors or line disconnects (like when you did at the start) then DLM will either enable interleaving or buff up the noise margin or both, there is also varying levels of interleaving so its more than just a on/off setting now.

I think I remember telling you this a week or so back.

I would ring up BTs tech support and explain the line stability was not the line but you playing around with the modem and ask them to reset the profile to its default, then after that plug it in to the router and leave it alone on 24/7.
