I am receiving a NINTENDO ERROR CODE 51331 on my console and I am not able to connect to the internet. I have performed the connection test but still I am not able to sort it. Need help immediately.
The error code you have received signifies that there is an ambiguity in the authentication process of Wii and the router. This is due to the refusal of connection by the router due to an incorrect security key.
The first you can try out to change the security type in the Wii settings to WPA2_PSK and then test your connection. Also, check that you are using the correct password. If the problem persists, try updating the security setting within the internet settings. If the error does not resolve even then power-cycle the modem and the router.
