Cant get this wireless thingy straight in my head. Have a laptop only. No fixed PC. Got broadband, then decided to get a router so that I can move around the house. All was fine yesterday but not so good today. Wont connect to internet now. (I think someone pulled the plug on router although nobody will admit it) Do I need to reconnect router to laptop again? Also email doesnt work. Still looking for old dial up connection.
