@DRPick Does the app show that the XE75 and the M4 are interconnected via Ethernet backhaul instead of wifi backhaul?

  @yves_b 

hello, in the app i only see an icon for wifi - ie it snot specifically saying either but it "looks" like only wifi (and if it was Etrhernet I would assume a rock solid stong connection?)

  @DRPick If it was using Ethernet as backhaul, you would see a cable icon instead of a wifi icon.

If you display the details of a satellite, it would state wich combination of media you are using as backhaul.

I suspect that the Powerline connection is not operational.  Could you test it by connecting a device to a Deco via Powerline?

  @yves_b yup tested it with a NAS and that appears on the network, so I know the Powerline is working.

I don;t see any option in the app to force it to use ethernet as backhaul 

  @DRPick Are the decos is router mode or access point mode? Also if you look at the LAN IP setting in the advanced section compare that with the Internet connection setting. The subnet mask have to be the same if they aren't then your decos may not be communicating properly.

  @DRPick It should use Ethernet as backhaul if it detects an Ethernet connection between two Decos.

  @yves_b well good to know it SHOULD, just can't get it to actually DO ;-)

the main deco is getting the IP subnet form the router, the others are getting theirs from something else (presumably the Deco, so need to play a bit more there)

i'll have another re-org this weekend see if i can get it working within one room, then try getting it working across rest of the house

There is no option in the app to force it to use Ethernet as backhaul.  Ethernet is the preferred backhaul, and will be used if the Deco detects an Ethernet connection to another Deco.
