AR300M-14c-NOR authentication error failed

I just got the AR300M-14c-NOR and set it up with my laptop and home wifi but when I tried to connect a Samsung phone and Amazon Fire HD in both instances after entering my new password I received “authentication error failed.”

Any hints, am I doing something wrong?

I got the router to screencast downloaded movies from my phone or Amazon Fire to a TV with Amazon Firestick in my van when I’m off grid and trying to create a network between devices…

Sorry, I didn’t understand what you meant. Your Samsung phone and Amazon Fire HD can’t connect to the Wi-Fi of the AR300M, or can’t access the admin panel?

I figured it out.

I was entering the newly created admin password, but to connect to the router with my phone and Fire, I used the Gl iNet default password and was able to connect.
