I've spent the better part of a month trying to get my Wii to connect to the internet.
I've done all of the tutorials, all of the troubleshooting, even checked with my own modem's site and my ISP site, it refuses to connect.
The system can locate my wifi, but when i enter my security code, I get error 51330. Even when I changed my security settings to open so there was no code needed I still got 51330.
I've tried channel 1 and 11, taken my modem off stealth mode, power cycled, reset.. changed codes several times and nothing works. I'm starting to think the Wii is just simply broken.
It has been connected to a modem, (not this one which is a 2Wire 2701HG) in the past and I remember i did have trouble with that but after following troubleshooting tips, it worked for a yr.
I'm sure there isn't anything left for me to do, but I figure I should check here before I give up completely.
Unfortunately it does seem like you have tried all the troubleshooting tips (copy&pasted below) and nothing has been able to correct this, so probably the best thing to do now is give a call to Nintendo's 1-800-255-3700 (6 am ~ 7 pm Pacific, everyday) Customer Service number and one of the service representatives will see if they can determine if something was missed and if still no luck, set up a repair if the Wi-Fi has gone out on your console.
Unable to connect to your wireless network
Likely cause: It appears that the security settings entered into the Wii console are not the same as what your wireless router is set to allow.
How to fix: Make sure the security key and security type are entered into the Wii exactly as they appear in your router's settings.

Did this connection used to work but has suddenly stopped? "Power cycle" your router and modem. To do this, unplug both the modem and the router from the power outlet. Wait a few minutes, and plug the modem back in. Wait a couple of minutes for the modem to initialize, then plug in the router. Try to connect the Wii, Nintendo DS, or Nintendo 3DS online and test for proper response.
