Nintendo Land Question
I can tell you that I've had this problem. I tested it again with the wireless sensor bar I had for my Wii, and use it for the Wii U. For me at least, I was having trouble getting that Wii U sensor bar to work right.
This happened to me once. I went to the menu and re-synced the Wiimote, and had no problems after that.
Make sure the sensor bar is plugged in all the way. It should pop into place.
You can point a camera (like on a phone) at the sensor bar and see if it's on.
