Instructions
Place your two Xbox 360 consoles are in the same room. Insert an Ethernet cable into the labeled port behind the console and insert the other end in the same way on the other system.
Connect the consoles to separate TVs and follow the onscreen instructions for system link game playing.
Turn on both consoles if they are in separate rooms. Navigate to "My Xbox" and then "Settings" on one console.
Press "A" on "Network Settings" to select it.
Click "Configure Settings" and then "Scan for Network."
Press "A" on "Create Ad-hoc Network." This network will be used to link the other console to this one.
Fill in your network information. This is the same router information your computer would require (SSID and password).
Navigate to the network settings for the second console. Scan for nearby networks and connect to the first console.
