XBOX LIVE CONNECTION: GRRRRRR!!!!

So, I'm trying to use my ibook g4 as a wireless bridge for my xbox to connect to live. I've turned on the internet sharing, set all the proper IP addresses and I can get up to trying to find the DNS server, but it can't find my damn router! Furthermore, when the box is connected to my ibook, the ibook can no longer access the internet as the ethernet port has taken over the Internet connection. How do I get it so that I can:
1: get the xbox to see the router
2: restore the airport as the primary Internet connection for the ibook?

I wish I can answer that, but I have no I-book or connection like that, to answer this. I'm using a more standard router connected to a cable-line and have been using it as well as being media connected to my PC, on the same network.

I'm probably going to add a wireless router to my current router so my pocket systems can communicate over the same network.

FUCK YEA!!! I got it after many hours of yelling and hair pulling. Now to sign on and get to killing stuff...
