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.
