@Alexandre. 

Thanks a lot for that.

I kind of expected that to be the case but hoped that the more 'complex', as you rightly put it, solution would have been possible. Wishful thinking obviously..

It's a shame as for many people, this would be a really good solution to creating the most efficient and greatest backhaul throughput. I suspect that it's very complicated to achieve though, hence the 'one or other' approach.

I wonder if the Netgear Orbi achieves this or in fact if any of the tri-band systems are capable of this.

@Stevieruss 

I have definite answer now. I've got additional M5 and wired it. On startup, this is what it reports in logs:

daemon.notice awn[1214]: [awnd_eth_handle_neigh:3941]: Activaing Ethernet backhaul in eth1, disconnect other backhuals.

daemon.notice awn[1214]: [awnd_eth_handle_neigh:3961]: Ethernet backhaul is active now.

Absolutely clear. I am sure M9 follows the same logic.

@Alexandre. 
 

Thanks for that. A definitive answer for sure!!

This looks like a common thing with Ethernet back haul. I'm informed that the Netgear Orbi does something very similar. Many thanks

I added the powerline adapter TL-PA8010P KIT as Ethernet backhaul to my Deco M4 (2packs). It connects main unit (upstairs) to satellite node(downstairs). I managed 140mbps wifi speed near the satellite node . My house has 3-phase power supply on 1 DB box so I bought AV2 compliant powerline adapters. The main & satellite nodes have the same wifi speed now. Also noticed that "mesh" function works because previously when i am upstairs my phone still connects to ground floor node. When i toggle wifi to connect to nearest upstair's node, it will reconnect back to ground floor node when I check after a few hours? Now the "mesh" feature works as expected after installing the powerline ethernet backhaul my phone switches correctly to nearest node. Better than getting the Deco P9 because the TL-PA8010P has passthru' sockets and I don't have to waste 2 wall sockets compared to using Deco P9.

@Mcwong644 I've got the orbi RBK50 which is so powerful that it manages to penetrate lath and plaster  

with metal mesh walls which nothing previously has managed to do without serious drop off. I tried the power line adapters which worked fine in our old house but suffer from too much noise on the single phase board we have. I suspect this is an issue for others as well.
