I believe it is to do with Tiscali moving over to TalkTalk. I was informed by TalkTalk that it would be a faster service - but only in the past month i have been getting major problems intermittent connection. I wouldn't do too much to your router etc. I have my laptop connected wirelessly and it still happens even thought they are on different ip address. I think Tiscali probably know but they have been given the party line to say everything is ok from their end. Imagine if they admitted it wasn't they would be losing all the Tiscali customers to other ISP providers. It wouldn't be good for TalkTalks reputation, so they will say that it isn't their fault. Tiscali won't be too bothered as they have new masters now.
