I reccently got the 360 about two months ago and I'm now just wanting to try xbox live. Problem is... when I tried xbox said my IP server wasn't connected? Now there are several computers around the house and I'm using one of the extra computers that uses a network adapter in order to have internet access. So I have the ethernet cable connected to the back of the 360 as well as at the back of the tower. Why isn't it still not working? What am I doing wrong?
