Hi,

I've just bought and set up 3 P9's, two in the main house and 1 in the den (garage) separate from the house.

They're all showing as communicating via WiFi only currently, Office (1st floor) is connected to Main (ground floor), Den (garage) is connected to Office.

Two days ago when setting up it showed the Den as connected to both office and PLC 5.0/2.4. (This should prove they can communicate though my house wiring)

I've got them configured so the main SSID is 5.0&2.4, and the guest network is purely 2.4 for some older WiFi systems I have which don't play well with 5 or dual band. 
 

the download/upload speeds from the den are pretty slow since it's bouncing through the WiFi mesh, my preference would be power line... is there anyway to make the PLC priority over the mesh? Or reasons why it's not showing both now? 
 

I also have 2x M5 units I'm looking to plug in on the top floor, so need the mesh network still enabled for these.

Thanks for any support.
