EDIT: Just for everyone's info if you are using WPA2 you should be safe for now but for all of you using TKIP time to upgrade. Of course just last year I was doing consulting and there were a ton of businesses still using WEP64. If you want to have fun you can use an atheros card and backtrack4 to crack WEP 128 in under 5 minutes with little knowledge of what is actually going on.
