AC750 Wifi Range Extender Wifi Password error message - but password is right

[luckyshepherd]

Like so many I have connected my AC750 Wifi Range Extender Model EX3110 to my home Router, but none of my devices will connect to the new EXT networks as the message incorrect password is coming up, even though I know the password to be correct.  Any suggestions for a quick solve please, I've tried for two hours and it's above my capabilities.  Thanks in advance

What firmware are you on?

What are all the led's on the front doing? list which one and color/blinking/solid. 

What router is it connected to?

did you set it up via wps? Or did you use the setup wizard?

It wouldn't be the first time that a password had issues. Its usually because there's a hidden space or special character somewhere in the password. I'd log into the router, change the password and NOT use any autofill options. autofill is very good at changing what you've entered. If its on, disable it while setting the password. Make sure there's no spaces or special characters in the password. Then reset the extender and use the setup wizard on the extender for setup. Not WPS. 

Here's the support site for the Ex3110 with manual, firmware, setup instructions, and troubleshooting.
