It's a strange old problem!
I don't use p2p but I do use newsgroups, but the problem only ever happens with web pages? I've put the splitter back now, can't miss the footy can I
, and not had a problem yet so I think unless it get's worse I'm goping to leave it alone!
One thing I have noticed is my TV sometimes has random audio dropouts for a few seconds on a channel on odd days, just wondering if that is the STB's version of the modem rebooting?
