I lost my internet connection for a week while AOL (yes I know!) faffed about.Since I got it back there is a lot of noise on the line which disappears when the router (Speedtouch 580)is turned off. I have tried other routers and the noise still appears.Has anyone came across this problem before? TIA, Peter. Ps BT say the line tests ok.
You could also try BT Quiet Line Test Dial 17070 and listen for any noise. I had a similar problem about 3 years ago and it turned out to be a bad connection between the local exchange and my house. (A bad filter is more likely)
