Hi and Welcome. My Name is ***** ***** I look forward to assisting you today with your question.
The authentication problem indicates that either you are using a wrong password ***** the router configuration doesn't work on Nook. Are you sure you are using correct password ?
I don't understand. All I asked is a question whether you are using right password ***** not, so I could give you correct instructions to solve the problem. This is not my final answer, it is only a beginning of communication. Don't you want help ?
If you don't want help, please contact***@******.*** to cancel this question and request refund.
Of course I'm familiar with Nook. Your question is "my nook has an "authentication problem" with my WIFI help"
This doesn't tell much. That authentication error means that you are not using correct password ***** the secutiry type of router is wrong.
Have you tried restarting your Nook ?
