I recently got a laptop from a friend. The computer won't connect to any wifi at all. It will connect when I use an ethernet cable. I have no idea what's wrong, help?! :(

I have windows 7 ultimate, let me know what information you need.

what happens when you try to connect ?
does it see the wireless ?
are you using a wireless password - does it ask for the password

did the pc originally come with ultimate - I have seen issues where networking does not work on non-genuine copies
