Nintendo Wii U GamePad Not Syncing

Check to ensure that there are no other Wii U consoles or Wii U GamePads that are currently powered in your household. If there are multiple devices powered, this can cause confusion in proper syncing.

Make sure that there are no other powered devices that can cause interference with your GamePad syncing. Try moving wireless devices, such as cell phones or tablets, three to four feet away from the Wii U console and GamePad while syncing.

Unplug the power cord from the console and leave it alone for 30 seconds. Then, press and hold the Wii U GamePad power button until the GamePad powers off. Wait for 15 seconds before powering back on the Wii U GamePad and plugging the console back in.
