@David-TP 

hey David,

just made a setup you suggested - the "Flur" P7 after some time got online, however I do not see the PLC- connection in its status even Power supply LED is green. One of the Smart Home Servers (wired to Flur P7) shows that it has no access to the cloud, probably due to weak signal, however YouTube works if I my smartphone is served by Flur P7 mesh.

BR,

  @David-TP the Deco P7 are in use since March 2019.

Just performed another test:

1. Set Deco P7 as a main

2. Connected x50 to P7 via Ethernet

3. Let another x50 running.

Result: The Flur P7 is online and says it has strong PLC connection. Apparently PLC works properly when P7 is a main Deco.
 

In case when x50 is a main Deco, could be that both P7 perform a proper handshake (reason for green power supply LED), the WiFi mesh gets refused by Flur P7 (assuming PLC works), but PLC finally does not work since P7 is nit the main Deco?
 

BR,

  Now I try to roll back the settings to setup x50 as a main deco and I cannot manage it - it complains that one of the Decos does not support EasyMesh and it offers me to deactivate it. Finally it does not allow me to deactivate it. Is there any way to change the main deco?
