How can I connect to Xbox Live through my computer?
“Don’t know if this would work but assuming the PC is running Windows XP. a) Get an Ethernet cross over cable. b) Connect the wired NIC from the PC to NIC port on the 360 using the cable. c) Ensure the wired and wireless connections have static IP address assignments – it just makes life easier. d) On the PC goto Control Panel, Network Connections. Highlight the wireless and wired NIC connections. With both highlighted do a right click and Add to bridge. Setup the bridge config as your network requires. Like I say don’t know if this will work in practice but give it a go.
