Hello Moedm
If you are using Fedora 7 there is a pretty good howto here:
http://www.fedoraguide.info/index.ph..._drivers_howto
Ndiswrapper is a way of using your windows wireless card drivers in Linux
If you were using Fedora 8 or if you upgrade though the advice would be completely different.
Read the howto in conjunction with the section following it in the guide and it should give you all the information you need.
It's the one I followed when I still used Fedora 7.
Do be aware though that the first part is talking generally about the use of ndiswrapper and where it talks about specific driver files you will need to substitute those which were supplied with your card.
Post back if you have any problems
