Uh yeah, as said above we cannot help when such vague information is presented to us...
It's a Netgear card is all I know. It's a card plugged into the computer...NOT an actual router? Do you have a router to connect too? Do you have a wireless network? What signal is the network, a? b? g? Does the card match the network signal?
A lot of questions we need to address to even begin to help.
