Stealing wireless internet

[trevorwc]

I know there was a thread a while back about whether or not it is okay to steal wireless internet from a neighbor. That's not what I want to know...as I'm fine with doing it. I just don't know how.

My girlfriend moved into a new apartment over the weekend, and her roomate was able to pick up a neighbor's wireless internet on her laptop. My girlfriend has a desktop in her room, and I'd like to equip it to do the same. What do I need?
