Well, I took your advice, and decided to start off simple and try and get an IP through the modem first. I unplugged the modem and the Xbox, and let it sit for a few mins. I then plugged in the modem and let it get a signal and light up. Then I turned on the xbox and tried the test.........No luck!
So, I looked around the options, and saw a setting for Restore Default Settings...Well, all my settings were on Automatic still, so I figured it woulnd't change anything, but I gave it a try. Well, after hitting that option, I tried to connect again, and low and behold it connected me. I can't believe that I missed it and it was so simple. I am not sure what the default settings change, but it worked. I was also shocked that I never saw that to be reccomnded anywhere online. Not the Xbox or MS site, or any fourms I have read.
So, if you can't get an IP address, try to reset the defualt settings option in the network settings screen. It worked for me. Plus, I was able to use the wireless adaptor with no problem, so I may just run it wired from now on, and sell my adaptor....maybe someone else needs one....
Thanks for the help anyways....
