I have a cable modem hooked to my PC and when I want to get on Live I have to take it from the PC and hook it directly to my 360. This has been working fine since I got my 360 but now I can not connect, when I run the test it's having a problem with the IP address.
Yesterday I was told to write down the IP address from my PC and enter it in the network settings for the 360 but after doing this I still have the same problem.
