Wired Connection

The best way to play GameCube LAN on XLink Kai is with a fully wired set up. You will get the lowest latency (ping) and most stable connection possible.

Connect your GameCube and computer to your router with Ethernet cables as shown below:

Wireless with PC/Mac/Raspberry Pi

If it is impossible to use a wired connection, WiFi can be used instead but the console must be connected directly to the PC/Mac/Raspberry Pi with an Ethernet cable. The computer running XLink Kai can not be fully wireless and there must be a wired connection to the computer for the network interface going towards the GameCube console.

If you computer does not have an Ethernet port a USB Ethernet adapter can be used.
