If you are using a Netgear wireless router, disable the SPI firewall setting which is usually found under the WAN Settings of your wireless router.
If you are attempting to connect your Wii console online using the Nintendo Wireless (Wi-Fi) USB Connector and you receive this error :
If your PC is using security features or programs such as a firewall, antivirus, or anti-spyware, check all settings of these security features or programs to allow a successful connection.
You may try adding the following programs to your firewall list of "Trusted" applications

• Nintendo Wi-Fi Connector USB (NintendoWFCReg.exe)

Temporarily disable your router's firewall which may allow the Wii console to connect online to receive a system update. After, you may turn your firewall back on.
