My kid has a Wii. I finally figured out how to sync the red buttons so the nunchucks will work. But now every so often the nunchucks don't work and I have to re-sync it. Does this happen to everyone else? I would think you would only have to do this with a battery change. Ours seems to every other day to un-sync itself and since the kids don't know how to do it, I'm always being called to fix the Wii. What is going on?:) :)

My kids got a Wii for Christmas and we have not experienced this problem. Sounds like a defective controller or console.

Mine doesn't do that either. Do you have a warranty for the Wii and equipment? I would see if you can get a refund for the controller or send in for another one.

Mine has never done that, even when I change the batteries all I have to do is press the A button for it to sync again.
