Mine is playing up also, but within 30 seconds of connection the only thing that remains connected is my limewire connection, and I can still download music. Everything else just drops..internet explorer, mozilla firefox, msn messenger etc. My computer is clean from viruses, spware etc but when I rang BT they said to re-install windows. Their answer to everything is re-installing windows. It is really frustrating cos in work I cant access msn messenger and I use that quite a lot at home.
