Authentication problem - tablet


AC Question

Today my Nextbook Ares lollipop tablet keeps saying Authentication Problem & won't connect to the wifi. I reset the router. I turned on the airplane mode for a bit. I forgot the network and reentered the password. I restarted the device several times. No other device in the house has issues. Just the tablet.

I forgot the network and reentered the password.
That will do it - unless:

1. You forgot the password and you're typing in the wrong one. (Try it with another device. And remember - case counts.)

2. There's something wrong with the tablet's wifi adapter. (Make sure the router is set for AES encryption, not TKIP or TKIP+AES. Some phones develop problems authenticating to TKIP. [If you have to reset it, you'll have to reconnect all your other devices.])
