|Get a Wireless Gaming Adapter (WGA). It is what is known as a Wireless Bridge which can plug directly into the the Game box through the Ethernet connection.|
You set it up the same way you did with your wireless router. First, you hook it into your computer to configure it unless the game machine has Internet Explorer on it. It will come with a static IP setup on it in its instructions. You just put that IP into your Internet Explorer to get to the configuration page then when it is setup pug it into the game machine. It will think you have a direct connection through a wire.
