Anyone know about Linux systems? I got a laptop from a friend, wiped it, and I'm running Ubuntu 10.04. We have a guest wireless access at work, but my machine is not connecting to it. It's got full signal strength, and I've connected to other wireless networks before, just not this one. Can anyone help?

I'm not the most computer savvy person ever, but I've learned a lot, and that's part of the reason why I started running Linux instead of Windows. (Well, that and I F'n hate windows...) Just a minor hiccup, and another step on the learning curve.
