A couple of days ago I was trying to set up ethernet backhaul between 2 slave decos when I noticed a new firmware upgrade. All the slave decos were connected to the main deco when I started the upgrade (1.4.4 Build 20200221 Rel. 65392). I upgraded from the app on android btw. When the update was done I continued my ethernet backhaul operation when I noticed that one of the decos was disconnected (no wifi from it, and it was flashing orange as far as I remember. I checked the app and it said the deco was fine and working. I then checked the firmware update and I noticed that my other 2 decos were running on 1.4.4 Build 20200221 Rel. 65392 whilst this slave deco was running on 1.1.5 Build 20170820 Rel. 00000. I have tried upgrading the firmware manually many times now but can't get the slave deco to upgrade itself. Any ideas?
