Connnection error 51330 on my Wii

I have been having the same problem as well with my Wii while trying to connect to my wireless router. I hope to share my experiences with all. Somehow or rather the wii only accepts wireless G bandwidth. If you have encountered any error, please refer to your user manual for the reference. Most of the time, its the inbuilt firewall of the router that is blocking the wii from connecting to the internet. There are some workaround to it.

You may wish to manual config the settings of the internet connection. You will need to acquire a few things from your ISP, 1) the proxy address and port number 2) MRU Number. for MRU number, its a number from 0-1500, this can only be acquired from your ISP. Tell them u need it to configure your third party router. they are more than willing to give it to you. For users that are based in singapore, the mru number for singnet is 1492, using proxy2.singnet.com.sg port 8080. hope these helps.

they won't know this error the error is on the wii, if you are using a wireless linksys router then the channel needs to be set to 11, fixed it for me, try changing to various chanles ad make sure it's set to g only, if you use mixed mode it will only work intermitently for some reason, if your using wired adapter I have no advice, i dont own one nor have i used one

Call Nintendo they will need to exhange your console. 1-800-255-3700

one option is try choosing a different type for your password...i've had the same error before and what i did was to change the password type e.g. from wpa aes-tkip to wpa-aes passphrase (this option will appear during your wii internet connection set-up as you would probably know by now) and everything right after started to fall in place perfectly, just try what password type will work for you...my wii started connecting to my router and never had the same error code ever since.

call Nintendo
