Error when trying to connect Wii to Airport Extreme

THIS WORKED for me... hope it works for you: 1) Go into Applications>Utilities>AirPort Admin Utility>Configure. If it says "update available," go ahead and update it. 2) Change the channel to 1 or 11 (not sure this is necessary). 3) Disable WEP Security (Wii will stop asking for password by doing this - turn it back on whenever you don't need the Wii for long periods of time). When you hit "Update" to save the new settings, base unit will automatically restart. 4) Go back to the Wii, clear the old internet settings, restart it and go back in. This time, it should not ask for a password, and should tell you there's Wii updates, and ask you if you want them; update it. If a progression bar comes up, you're in business. When I took it for a test drive, it said there was another update, but skipped over it and started working.

For me, in my Airport Admin Utility settings, I had the option "Create a closed network" checked. Uncheck that and the Wii can see your Airport. You can close it again after it's connected.
