Soudns like a router problem.
Wireless Router:
1. Make sure you are using a "broadband" internet connection, such as high speed cable or DSL. Slower connection types, such as dial-up, may not work properly with the Wii console. If you are unsure what type of connection you have, please contact your Internet Service Provider (ISP) for more information.
2. Try adjusting the "Channel" your wireless router broadcasts on. We highly recommend setting your wireless router to either channel 1 or 11. Be sure to try both channels if the first one you try does not work. This can potentially increase the download speed. For information on accessing your router's settings, click here to select the brand name and model number of your router (if available). (The "Channel" setting is typically found in the "Wireless" section of your router's setup utility.)
3. Make sure that any other interfering devices, such as microwaves and cordless phones, are turned off. Wirless keyboards and mice may also cause interference.
4. If this error occurs regularly, it is may be a connection problem related to the firewall settings of your wireless router. It may be necessary to disable wireless security on the router. For information on accessing your router's settings, click here to select the brand name and model number of your router (if available). For detailed information on where to locate your router's firewall settings, please consult the owner's manual for your router, or contact the router 's manufacturer. (More about firewalls)
5. Are you using a Netgear brand wireless router? Our expeirence shows disabling the "SPI Firewall" of the router may help the connection. The "SPI Firewall" option is typically found under the "WAN Setup" tab of the router's settings.
Nintendo Wi-Fi USB Connector
1. Make sure you are using a "broadband" internet connection, such as high speed cable or DSL. Slower connection types, such as dial-up, may not work properly with the Wii console. If you are unsure what type of connection you have, please contact your Internet Service Provider (ISP) for more information.
2. Does your PC have any security programs (firewall, anti-virus, anti-spyware, anti-adware, etc.) installed? If you are using the Nintendo Wi-Fi USB Connector, and have a software firewall or other computer security program installed on your computer, there may be additional steps you must complete to allow a successful connection.
"Trusted" Applications:
If your firewall or PC security program keeps a list of trusted applications (also known as a "trusted zone"), the following programs are installed with the Nintendo Wi-Fi USB Connector, and require internet communications. If prompted by your firewall or PC security program, add these to the list of trusted applications. This information may also apply to certain computer security applications, such as anti-virus, anti-spyware, etc.:
o Nintendo Wi-Fi Connector USB (NintendoWFCReg.exe)
o Setup.exe (when installing the USB Connector)
o SoftAPInstDrv.bin
o mdriver.exe
3. If you are using a router, you may need to temporarily disable the router's firewall to allow the Wii console to connect online and receive a system update. Once the update is received, you can turn the firewall back on. For information on locating and disabling your router's firewall, please consult the router's manual or contact the manufacturer of the router.
