Nintendo Wii U Console Not Recognizing GamePad

If the GamePad will not connect to the console, check that the antennas within the GamePad are connected correctly.

Sometimes random freezing can occur after the system has been plugged in for too long. To rest, turn off game console and gamepad, unplug the game console from the power brick and the power brick from the wall outlet, and wait 10-15 seconds before reconnecting.

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.
