The LAN Adapter is an accessory for Nintendo home consoles that allows local and online play through a wired connection, depending on the system and game. It was launched in October 2002 for the GameCube and The Mario Kart series
The Nintendo GameCube could be upgraded to feature LAN support through a LAN Adapter, sold separately. It connected to Serial Port 1 on the GameCube, and it is incompatible with other systems like the Wii or Switch. Only seven GameCube games support the adapter: four support Internet connectivity only, three support LAN connectivity only, and one (Homeland) supports both.
Mario Kart: Double Dash!! supports LAN connectivity only. Up to 16 systems can be linked together. Up to 8 players can play if each controls one kart, or up to 16 can play if each controls a passenger in a kart.
Wii and Wii U
The Wii LAN Adapter allows a Wii or Wii U system to connect to the Internet using a wired connection. This is only required when wireless connectivity is not in use, as these systems connect to Wi-Fi networks without additional hardware.
The Nintendo Switch supports the Wii LAN Adapter for use in Switch games. Likewise, the new LAN Adapter with Nintendo Switch branding is also compatible with Wii and Wii U systems.
Mario Kart 8 Deluxe supports both Internet and LAN connectivity.
