Basically, I'm on a 20mbit cable connection provided by Virgin Media. During the morning/daytime it's brilliant. I get anywhere from 18-20mbit connection speeds.
Recently, in the evenings my connection has dropped down to anything under 5mbit, sometimes the speed even drops down to >1mbit.
I've tried all the normal tests (direct connection to the modem, changing the routers channel on the wireless etc.) but nothing seems to fix and the problem.
Has anyone else had/got this problem or any advice to fix it?
