In order to play games online with the Broadband Adapter, you will need an ethernet cable with an RJ45 connector ( shown below). You will likely already have this cable in your existing DSL or cable modem connection to your PC. If you do, you will need to remove this cable from the back of your PC and plug it into the Broadband Adapter to play Nintendo GameCube games online. However, some DSL or cable modems do not use an ethernet cable, and instead use a USB connector ( shown below). The Nintendo GameCube Broadband Adapter is not compatible with USB connectors.
