Things You'll Need
Instructions
Turn off the Xbox 360 console before removing any network adapter. It is OK to leave the PC on during this process.
Disconnect a wireless networking adapter from your Xbox 360 console if applicable. The wireless networking adapter may interfere with Ethernet connections because it becomes the primary network connector once configured.
Plug a Cat5e or Cat 6 cable into the rear of the Xbox 360 console. The Ethernet port is located next to the audio-video ports.
Insert the other end of the Ethernet cable into an Ethernet port on your PC.
Turn on the Xbox 360 console. After a few moments, your PC should recognize the local area network in the taskbar. The local area network represents the connection between the Xbox 360 and the PC.
