This error code usually indicates that the Wii console was able to connect to the Nintendo Wi-Fi USB Connector, but is blocked from reaching the appropriate server(s).
It is likely that the router in your network has a default IP address of either 192.168.0.1 or 192.168.1.1. This will need to be changed to 192.168.2.1. For details on changing this setting of your router, please consult your router's manual, or contact the manufacturer of the router.
