After months of use my tablet suddenly lost connection to the internet the other night and won't reconnect. (Authentication Problem). Other devices still connected and re-connected. Powered off and on modem and tablet several times. Tried "Forget network" and "Add new network" with no luck. Tablet connects to other internet sources, so that's not it, either. I even did a Reset to Factory Settings with no results. Anyone have any other ideas?
 
Solution
Authentication issues are often caused by not entering the wireless key exactly as it appears in the router configuration.

Check that uppercase & lowercase letters match, and make sure not to enter capital 'O' when it should be the number 0 (zero).
