Linksys WGA11B - Wireless-B Game Adapter
The Wireless-B Game Adapter gives any wired-Ethernet-equipped game console wireless connection capabilities. The Game Adapter can be used in two different ways. If you have an existing home wireless network with a cable or DSL Internet connection, the Game Adapter lets your PlayStation2, Xbox or GameCube attach to the network so you can get into online games without running wires to the game room. Or, use a pair of Game Adapters to form a cable-less cable between two game consoles for head-to-head gaming -- in the same room, or all the way across the house.
