When I go to wifi it says authenticing problemWhat exactly doesn't seem to be working?
With newer versions of Android, the device will silently switch from WiFi back to cell if the Wii connection does not have internet connectivity. If you put the device into Airplane mode first, then enable WiFi; you'll be able to connect without any problems. I have a Nexus 6P running Android 7.1.1 and that's the only way it will connect.
