I'll go with "you've had loads of line errors, possibly due to a line fault.. the DSLAM has interpreted this as unstable and lowered your target margin to increase stability".
I bet you the noise margin is now 15dB, and you'll be stuck at this speed for a few weeks / until the fault it fixed.
Try a phone at the master socket. If you can hear noise, call 151 and report a voice fault.
Yeah I hear noise but only when sum1 speaks , verry crackley. I have rang bt and they say my line should handle 7 meg and they will try and fix it , am debating switching to infinity , thanx for your post
People saying about line stats, when I go to that ip it's my routers cp, I see no "line stats"?
