I joined the 21st century this past weekend and purchased a wireless card. I needed one for our slide-a-thon this weekend, and I figured I could use one anyway for coffee shops, airports, etc.
It's a fairly generic Linksys card, which I selected in part because my web research tells me that it's supported by FreeBSD (which I currently have installed as part of a dual boot setup on my laptop). Unfortunately, I didn't have much luck getting it to work in FreeBSD. I'll have to play around some more.
