Things You'll Need
Instructions
Connect the Wii LAN Adapter to the USB port on the back of the Nintendo Wii. The USB port is a smaller port located just above the rear exhaust of the system.
Insert one end of the Ethernet cable into the Ethernet port on the Wii LAN adapter. The jack on the end of the cable should fit snugly into the Ethernet slot.
Connect the other end of the cable to your wired router or modem. The Ethernet port on the modem should look the same as the one on the Wii LAN Adapter.
