Somebody please help me. I am so frustrated right now. I just went and bought the newer xbox that is wifi ready. I bring it home, hook it all up and play a few games. Meanwhile, I notice that in between screens and when loading new games etc, it is loading really slow. I then shut it down and since then I cannot connect to the internet. It keeps saying that it cannot obtain an IP address. I have been thru all the xbox.com/support ideas with the exception of adding the xbox MAC address to router list of authorized addresses. I have other wireless devices that are working just fine. I am using a Linksys Wireless-g router - Model wrt54gL. PLEASE HELP!
