FJ-IR-WIFI-1NA doesn’t stay connected

Inherited 4x Fujitsu split units with ac cloud WiFi devices. I was able to reconfigure 3 of them to new WiFi, however it’s a total hit or miss whether I will see them connected to WiFi in the AC Cloud app. Seems they are constantly dropping off the network.

One of the units never enters “configuration mode” after holding button for 10 seconds or more. It always goes back to blinking red.
