If you have a router try going into it's setting and put the mAC address of you wii into the mac filtering settings on the router. The Wii mac address can be found in the internet settings of the wii.
This error is caused by the Wii being unable to connect to the access point.
To solve this error :
Try changing the channel of your wireless router to either channel 1 or channel 11 which can increase download speeds.
If your router is using WEP encryption
Ensure your key is hexadecimal, consisting of 0-9 or A-F only, no other special characters or letters.
64 bit encryption requires your WEP key to be 10 characters consisting of numbers or leters A through F.
128 bit encryption requires your WEP key to be 26 characters consisting of numbers or leters A through F.
If your router is using WPA encryption, the Wii is compatible with :
WPA - PSK(TKIP)
WPA - PSK(AES)
WPA2 - PSK(AES)
If your router is using MAC filtering, ensure the Wii MAC address has been added to the list of approved MAC address on your wireless router settings.
