I'll run you through my problem;

Purchased a new computer a few weeks ago. I decided to use the DLink adapter from an older computer, and it is installed correctly, no problems there.

I then performed a search for my router, being a BT Home Hub. The network adapter finds the Routers perfectly and even connects to it. The problem is though, that the Internet or any other program that requires a connection will work correctly.

I've tried;
Windows Messenger
ITunes
MSN Messenger
MSN Explorer

None of them work.

Anyone care to help me and tell me how I can resolve this problem?
