3com cards work well. I think pretty much all of them work. Linksys cards don't have any problems. Most of the Netgear cards work. You can find 3com cards at some shops used but still working great for like 5 bucks. I picked up 4 one time for a mere 15 bucks at a local shop..
Try searching, this is asked all the time. Also I'm moving this thread to Hardware, since its more suitable there.
