Belkin F5D7000 ver.7000 Network card issues

Hello,

I recently moved my Dell computer to my room and had to put a wireless card ( Belkin G F5D7000 ver.7000) into the computer. We had lost the disk for this network card but my brother said that I can just download it. So I downloaded it onto another computer and tranferred the driver onto the computer in question.

I installed the driver and it won't connect to the internet...well....it won't "see" any networks at all and I know for a fact that there are 4 networks in the area that even my laptop can connect to from my bedroom.

What have I done wrong?
