I'm switching to Ubuntu.

Hey guys. I'm switching OS'es from Windows to Ubuntu Linux. I'm first going to use it on my Compaq Armada 500 laptop. My main question is this: What wireless networking device would be best suited for this OS? Also, What WLAN utilities do you suggest I grab before I switch OS'es?

I want to switch to ubuntu but im not sure if my AOL connection would work. I don't think it would :(
