X20 1.20 fw and ethernet backhaul.
Just updated 2 x20 v4 to 1.20 ( main is v1 x20-4g)
My config is main, the 4g that is in the middle. That is connected to livingroom x20 (has better wifi link together. The livingroom is connected to garage x20 with lan. There are two tp-link basic switces between the long lan cable with a couple of devices.
This could also be issue with mobile app...
Now after 1.20 fw one of the basic x20 keeps disconnectin according to app and light in the deco is indicating the same, right after turning ethernet backhaul on. Main is near the garage, but wifi link is weak.
But actually even though the lan connected deco appears as missing, every device connected to it, with lan and wifi, are all online. App just shows that all of them are lan devices connected to the other x20 that still is visible.
All was working fine with last fw before 1.20. and all works ok if not using backhaul.
