I'm new, and am having some trouble with my wireless. I have an ASUS G1s, and am running Ubuntu 9.04. My wireless network does not appear under wireless connections, and I am thinking that I am missing a driver or something. Any solutions?

I cannot connect to the internet with my Linux comp. so I'm using my XP comp. I Just installed Linux, and don't really know much about it yet, so sorry for my ignorance ahead of time.
