I get 2 meg plus first thing in the morning (05:30), but in the evening, if I get a signal at all, it's around 50 - 300 KBPS, often there's nothing.
It's painful watching the pages refresh.
I've been on to Pipex and been through a lot of dianostics, now they want to send a BT engineer round to check my line, but surely if I get 2 meg in the morning, it must simply be the number of people using the system at peask times is too much for the supply system?
