Wireless Routers/Gateways provided by Internet Service Providers (such as Comcast, Time Warner, Road Runner, Charter, etc.):
The routers listed below are provided to customers by their Internet Service Providers (ISPs). Due to the way the Wii console interacts with these routers' firewalls (sometimes called an SPI firewall), it may not be able to connect online, even when using the Nintendo Wi-Fi USB Connector or the Wii LAN Adapter. If you are able to log in and disable the router's firewall (you may need to get a "super user" password from your ISP), you may be able to get the Wii console connected online. If you use an ISP that prevents the firewall or SPI firewall setting from being adjusted, or if you prefer not to adjust the router's firewall, there is a system update that may resolve the console's ability to connect with Nintendo's servers, enabling the use of some online features.
Please note that not all online features of the Wii console are updated with this system update. Access to the News, Weather and Everybody Votes channels, as well as any channels that utilize the WiiConnect24 feature, may be unaccessible or have limited function with this update. A future Wii console system update is in development that will enable the use of all of the Wii console's online features. Please check back for more information.
To download the system update to your Wii console, you will need to successfully connect your Wii console online. If your current connection through your ISP-provided router is preventing a connection, you will need to find an alternative online connection, such as taking your Wii console to a friend's house where there is a compatible internet connection. (If this option is not available to you, link here for information on other options.) Once you have connected the Wii console online, the system update will download and install. With this update, you should be able to download any future updates with your own internet connection.
