I recently moved into a house that has a wireless network, and I have a 360. I don't want to have to run wires everywhere or buy the adapter for the 360, I'm trying to extend the network using my router, then hook up the 360 using Ethernet off this router. But every time I try to get on Live from the 360, it fails. Can you do this? If so, what do I need to change on the 360 and/or the router?
