The ultimate solution to this problem is make the password visible as you print it. For some reason it does not print exactly as entered. When the number or letter is not correct erase and re-enter.

My solution was a bit deeper than most of the normally suggested fixes... I have a newer router (Netgear R7000) running newer firmware (DD_WRT) which allows detailed control of the radios on the antennas. So as it turns out (per Wi-Fi Spec) that the newer N channel antenna doesn't support the older WPA authentication... and I had previously configured mixed mode WPA/WPA2. Setting the router to WPA2 only resolved my random authentication error issue. Which also proves a bug in the android software running in my tablet was attempting to use the older WPA encryption on the newer N channel antenna. I have no idea if the factory standard firmware for the R7000 (or your router for that matter) comply with this corner case in the Wi-Fi specification, but I suspect not. If you have a newer router that supports N channel then you might give a try using just WPA2.
