CrunchBang Linux

I bought my MacBook Pro at the beginning of the school year when I went to college. I am now living in a dorm where I do not have access to wired internet connection, so I cannot just plug my computer in to download stuff. If need be I can of course borrow someone else's computer to download something and then just transfer it over with a flash drive.

Anyway, I have a virtually new MacBook Pro that I bought in August. Using refit I have dual-booted OS X and Crunchbang (obviously I am posting this from within OS X) but I cannot manage to get connected wirelessly to the internet. I have tried this many many times with many many distros and have never once been able to connect. I always seem to get confused or have something mess up. Can someone give me step by step instructions (or point me toward some simple ones) starting, if need be, from a fresh install as to how to get wifi working on my macbook pro? I am also completely willing to switch versions of Crunchbang if that would help.
