Moved to Other ISPs
I'm afraid the main problem is, most likely, the simple fact that you're on Sky Connect
If you read around here or various other forums you'll find that Connect is not very well thought of, to put it mildly...
I would always recommend Sky's LLU broadband (Unlimited, Everyday Lite), but I'd not wish Connect upon anyone.
If you want to try a more Sky-oriented forum, have a look at
Sky User
This is an on-going Connect thread at Sky user:
http://www.skyuser.co.uk/forum/sky-b...ect-users.html
And another one here at CF:
http://www.cableforum.co.uk/board/63...y-connect.html
You'll find similar tales of woe at
Digital Spy and other forums.
EDIT: I think there's one member here who works for Sky BB in some way. If he still does, maybe he;ll have better advice for you if he see this thread.
