Hi there,

I've been gearing up to purchase the Deco P9s with a plan to setup as follows: 1st P9 unit (into modem/router) utilising powerline extension to send signal to second P9 unit and then the second P9 connecting via ethernet to the third P9 unit in a second building. Seemed simple, then I read in FAQ/2401 the following:

"Q4: Can PLC Backhaul, Ethernet Backhaul and Wi-Fi Backhaul work at the same time?

PLC Backhaul and Wi-Fi Backhaul can work at the same time, while PLC Backhaul and Ethernet Backhaul can’t.

If there is no Ethernet cable between the Deco units, Wi-Fi Backhaul and PLC Backhaul will take effect at the same time.

If there is an Ethernet cable between the Deco units, then only Ethernet Backhaul will take effect."

From my understanding this means my proposed setup will not work since I will be trying to employ both the PLC and Ethernet backhaul methods.

However, that final line confuses me since in the same FAQ:

"Q2: To use the Ethernet Backhaul feature, do I need to wire all my Deco units?

Nope. You can set up one for wireless backhaul, and the other one for Ethernet backhaul as you want."

Maybe my understanding of the backhaul tech is off?

As it stands my interpretation is that the moment I connect an ethernet cable between any two Deco units the entire Mesh, i.e. all three units, will no longer be able to use the powerline functionality thus my proposed setup above: P1 <---powerline---> P2 would simply not connect.

Can anyone confirm if I am correct or not please?

Many thanks.
