So.  I've found out what my friend did.  He's connected to the internet without a WEP key, and he didn't use one when mine was at his place.
Martian - there is an option to automatically scan, but I don't have the option to use it.  It says that I need to press a button on my router to do so, but when I look for it, the router doesn't have it.  It is an older router, tho.  I'm going to rassle with it tomorrow.  I have found this site that should help:

note:  there's a link to wi-fi on the bottom of the page.
Something that it mentions is that my 2Wire may not support wifi.  I may need to get a WAP in order to get it to work.  But I'll figure all that out tomorrow.
