To solve this error :

Try uninstalling and reinstalling the Nintendo Wireless (Wi-Fi) USB Connector software.
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.
