Windows 7: Wireless Conection Deactivated!?

Hei, ive just bought a new gamer that got Windows 7 Ultimate 64bit as OS. Im in
the norwegian airforce and dont have anything but wireless network at my room!

The problem is that no matter which card/adapter I use the wireless network wont be activated! I have tried D-Link DWA140 USB adapter, with the drivers that follows the CD and I have downloaded the 64bit drivers from their homepage! I try to right-click and "activate" the connection, it then says "actiavating" --> "activated", but no difference at all, it still says deactivated!

I have now got me a ASUS PCE-N13 network card, but the same problems continues! ive tried the drivers from the CD and Downloaded them from ASUS's support page!

I believe it got something to do with my windows 7 options or something like that and not the card or adapter. The motherboard is ASUS PT6 Deluxe V2 and shouldn't have any trouble with the ASUS PCE-N13.

Please help me! im a gamer without web conection! :P
(sorry if its bad english)
