Wireless Card on Linux

Ok, I recently installed Red Hat Fedora...this is the first time I've ever used Linux, although I am very competent with Microsuck Windoze. Anyway, a friend of mine told me that my wireless card, a Linksys WPC55AG, was compatible with Linux. However I'm having trouble connecting to the internet. I beleive some wireless cards don't work under Linux, so does anybody know if this works under Linux or not? If it does, this may just be a stupid Linux-newb mistake.

I'm running a Dell Inspiron 1100.

In advance, much thanks for all the help!

Nielsosky13, looks like you have to add the MadWiFi kernel module for it to work.
