Can't connect a new scanner to Sense WiFi
I got a new Fujitsu xi500 scanner and can't connect it to my Sense router over WiFi. I swapped out the Sense router for my old router provided by my cable company and the scanner connected to that one without a problem. I then swapped back to Sense and it again will not connect. So it is specific to the Sense router. When trying to connect my scanner, I get as far as entering the password, but it does not connect. I am entering the correct password. I tried powering off and on Sense and it made no difference.
All of my other devices can connect to Sense without a problem, and I have been using Sense for about 6 weeks without a problem. Only this new scanner has a problem connecting. How to fix?
In the Sense app on my phone, the status is "Everything is Ok".
