Noticed this problem in the last week since the latest system update (nov 10) was installed...
If the Wii U has been powered off for a few minutes, and you try to start it by using either the power button on the console, or by using the power button on the Wii u Gamepad, then Gamepad powers up, and the Wii u starts to power up but sort of hangs and the TV screen remains black, but the blue power light on the front of the console indicates that it is powered on.. within a few seconds we get a message on the Wii U Gamepad that says "Could not connect to the Wii U console. Please move the Wii u Gamepad closer to the console. Then turn the controllers power off and on again"
Powering the controller on and off doesn't seem to make a difference. Ultimately I have to hold down the power button on the console and force a shutdown. If i now try to power the unit on again, everything works as expected and we are able to play games as usual. Again, if the system is powered off for more than a few minutes, we seem to have to do this exercise all over again to get it running. Are there any known issues with the latest system update? It just seems weird that we've had no problems since we bought the unit back in September and now suddenly its acting up since the system got updated.
I've tried all of the other obvious trouble shooting (moving the console away from tv, Wi-fi, etc) with no real results.
Anyone else had something similar happen and have a work around? or perhaps there is a way to uninstall the latest system update?
