New MacBook won't connect to the ineternet

I have a 17" MacBook Pro that I got about 1 month ago that will not connect to the internet in our house. We don't have our own internet and router but we live in an area with a lot of college students and my roommate is always able to connect to someone else's internet with his MacBook. I took my computer back to the Genius Bar at the Apple store and they gave me a whole new machine and the interent still doesn't work in my house. Has anyone else had any problems like this?!

So you're upset because you can't use your computer to steal internet access?

You're not going to get any help here. That would be against the forum rules.

Since you're technically stealing another person's internet, that would be against Mac-Forum rules, and thus, we can't really help you. Now if this were your own personal network, then we would all gladly help you out.

The question was I asked if anyone else has had this problem

You're asking if anybody else has had a problem stealing Internet? I'm still pretty sure that can't be discussed.

ok. How about "Joining an unlocked network"

How about paying for your own internet access.
