Anyone have a "WiiU Gamepad Not Connected" issue with their WiiU?

Make sure it's not right next to other equipment that use the same frequency, like smart tvs, cell phones, cordless home phones, microwaves, tablets, other consoles. Turning it on and off will likely make it use a different channel, solves the problem too.

Too many wifi devices nowadays, my laptop is picking up 8 different signals atm, and I have a free standing house in not a dense neighbourhood. How do people in apartments survive with wifi neighbours.
