I have an intermittant problem with my cable modem. Almost everyday usually early evening it loses connection to the internet. It can be when I am listening to internet radio and it suddenly stops or it can happen when I am away from the PC and when I return it is off.
I have found the easiest way to restore connection is to pull out the power plug and then it shows that it is looking for network address and then everything is OK till the next time
Modem is NTL home 100
