Issue since upgrading Deco M4 to 1.5.2: unable to find other deco
I have two Deco M4 setup as Access Point.
Main Deco is connected directly to my router, second one is connected using Ethernet Backaul. Everything was fine since I bought them.
This morning I have upgraded from 1.5.0 to 1.5.2. Since then, my second Deco is not found. LED is solid white but on the app or from the web interface, second deco is marked as "Disconnected from other decos".
I tried everything, I even reset both Decos. After resetting both Decos, I setup the main one again but as router. The second one was connected to it until I change the operation mode to AP. The main Deco had restarted and since then the second Deco won't connect (but LED is solid white and I can ping it).
I also tried to downgrade but I have "Operation failed" everytime.
Is this a bug? How to make everything work again?
