I just got our brand new 2022 Forest River Microlite 21FBRS this past Friday (9/17/21). The WiFiRanger unit was pre-installed. I went through the setup, registration, and connected it to our home WiFi (a solid mesh WiFi 6 setup). After I got it connected, it suggested, the firmware update just like the original author of this thread. I’m not sure what happened during the update, but it certainly did not work.
I’ve tried the factory reset sequence a couple of different times, but still nothing. No SSID being broadcast, nothing. I did log a ticket with support, so hopeful there is some trick to get this thing working again. Very disappointing experience on the first go-round with this unit. I’m not even sure where the unit is? There is just the switch on the inside of the door with the default SSID, etc.
