Ok I want to go online on my Wii, but when I set up the wireless connections, it always says, error code: 51330. Then when I went onto support.nintendo.com, it said that my error code had something to do with security, which is stupid because I didn't set ANY of the security features on my router(WEP, WPA, WPA-2, etc.) And unfortunately, I can't find my router model on support.nintendo.com, which is a D-Link DI-521M
Try a few of the suggestions here: http://www.wiichat.com/nintendo-wii-online/5465-wifi-error-51330-a.html
