I am attempting to hook a PC and a Xbox 360 up to one Ethernet cable in the wall. I am using a short Cat 5 cable that runs from the wall to a switch and then I have 2 Cat6 cables running from the switch to the xbox and pc. I get unidentified network error on my computer and no IP address error on my Xbox with this setup. The connection is fine when just running straight from the wall to the computer but does not work when running from the wall to the xbox. Wondering if anyone has any solutions.
