Alright I'm new to linux so bear with me. I just installed Hardy on my new computer that I just built. I finally got it to recognize my wireless card. It still defaults to wired connection even though I don't even have anything plugged into the ethernet port. So how do I make it default to wireless (and then if a favorite network is around connect to it)? It is a desktop but it will be moved between home and school every few months.

And also since I'm posting: I know it's the wrong forum but I also need help getting my nvidia GeForce 8800 GT graphics card drivers installed. Do you guys know a good tutorial or something off the top of your head to get that done?
