For those who have a Wii online:

This is probably the wrong forum to ask, but I'll ask on multiple. When I try to connect to the internet I get error code 51330.

Yes, my router is on the right mix.
Yes, my router is on "Mixed"
Yes, I'm putting in the right password.
Yes, I power cycled my router, reset it, etc.

I tried to connect without a password and it worked, but when I connected with a password it didn't. I looked on the website, and I did everything it said. The reason I have my password on is so that my family can connect to the internet.

I'm using WPA Person, AES. I tried TKIP but that didn't work either, anyone have a clue?

My Wii uses the same WPA AES (don't set it to TKIP if your router is using AES) key as the rest of the wireless devices in the house. The laptops, Nintendo DS, and Wii all require that key to get online. The only thing I can tell you is to make sure that you have the key entirely correct on the Wii. It should work flawlessly.

A quick trip to google suggests changing your channel on the router to 1 or 11, as well as turning your Wii so that it lays flat, not standing straight up and down.

What router do you have? Did you try to update your router's firmware yet?
