My little brother has a problem I've been trying to help him with, but I haven't been able to figure anything out. He's been trying to connect his laptop to his university roommate's AirPort network (which appears to have WPA encryption), but he doesn't know the passphrase. The roommate's technical skills stop at typing, so he's been no help at all; he doesn't even know his own network password, because he ran a CD or utility or something along those lines to set up security in the first place. Initially, I tried connecting to the AirPort to take a peek at the settings inside, but I haven't been able to find the correct IP address (this is the only router I've ever seen where the gateway address isn't where the router is actually located). So, we reverted to borrowing the roommate's computer and trying to retrieve the stored password from there. This is something I could figure out very quickly on Windows, but something I'm utterly incapable of on a Mac. Is it possible, and if so, how? Please make your instructions comprehensive and accurate, as I'll be delivering them over the phone without the benefit of a Mac to follow along on. Thanks!
