I've been having this problem for awhile, yet I have no idea why. Almost everytime when it is late at night(usually around 11:00pm or 12:00amPST/12:00am or 1:00am MST) and I try to connect my Wii U to the internet, I will get an error that says there is no connection point in range even when all of my other devices work including my 3DS. Also by morning it will work again with not problems at all.
Just checked and now my internet seems to be working I think. Still confused why it does keep doing this though.
