I have a Samsung Galaxy Camera running Android 4.1.2. All of the sudden, the device has stopped connecting to wifi. No matter the network, public or private, I get a message saying "Authentication error occurred" when I try to connect. It seems to be a device problem as I have no problem connecting to the same networks with any other device I own. I've tried all sorts of combinations of turning wifi and the device on and off. No luck so far. Any thoughts? Thanks!
