Hey there, I've had sky broadband for a few months now. Up till now its been working fine however recently it's not connected. It just comes up with ''unidentified network'' with the little yellow hazard sign. I'm using windows 7. Also my 2 laptops can connect wirelessly no problems and my xbox (wired to the routerr can also connect) however my wired PC cannot. I've had a friend over to look at this he took it away and it worked!....for a day and has now gone back. could anyone help, thanks
