Configuration Guide How to set up Ethernet Backhaul with your Deco devices
Ethernet Backhaul is a feature that makes it possible to wire the Deco units together to optimize the bandwidth and network stability.
Normally, after wired Deco units with an Ethernet cable, the Ethernet backhaul will take effect automatically.
Typical connection structures for Ethernet Backhaul
QA
Q1: Which switch models support Ethernet backhaul?
Most of the switches on the market support Deco's Ethernet backhaul feature. If you don’t have a switch or if your switch is verified not compatible with Deco Ethernet Backhaul, the following models will be a good choice:https://www.tp-link.com/home-networking/all-soho-switch/
Q2: To use the Ethernet Backhaul feature, do I need to wire all my Deco units?
Nope. The following network layout works as well.
Q3: How do I know if Ethernet Backhaul takes effect?
Q4: Why my satellite Deco's signal source shows "Wi-Fi" instead of "Ethernet" in the Deco app even if the main Deco and the satellite Deco are connected to the same switch?
Please refer to the suggestions on this link:Ethernet Backhaul not working
Q5: Why my Deco units become unstable once they're connected via a switch?
The Deco Ethernet backhaul feature is based on the standard IEEE 1905.1 protocol. However, we find that some switches, mainly the D-Link switches, will not forward packets based on IEEE 1905.1 protocol, causing all Deco units in a network loop and becoming quite unstable, you might consider changing another switch or contacting switch’s support directly. TP-Link Switches are mostly compatible with our Deco’s Ethernet backhaul.
Q6: Can I set up different Deco models such as M5 and M9 Plus together through Ethernet backhaul?
Yes, just configure and add different Deco models in the same Deco network. After that, you can wire them to set up the Ethernet backhaul connection.
You could refer to the link to learn how to add different Deco models in the same network.
Q7: Can I use one Ethernet port on the Deco for Ethernet backhaul and the other to connect a computer?
Yes. For more details, please refer to How to use Ethernet Ports on Deco?
Q8: Can I use a pair of powerline adapters to build Ethernet Backhaul, like Main Deco---master Powerline adapter~~~extended Powerline adapter---satellite Deco?
Yes and please keep in mind that the Ethernet Backhaul speed now will depend on both the Ethernet cable quality and Powerline rate.

@Dekel Please try to simplify the topology by disconnecting the D-Link switch as some D-Link switches have been verified destroying the Ethernet Backhaul between Decos.

Once I replaced my old d-link switches with the new TP-Link's mentioned in my post everything worked as expected all with wired backhall. Life is good when your covered in stable, consiustant Wi-Fi
Thankls you very much
Cheers

I knew you are going to say that.. and I completely disconnected the D-Link from the topology.
Still the problem remains.

@Dekel Seems strange. Firstly, could you try to wire the two Deco units directly to check if they can form an Ethernet connection?
If yes, then the issue could be narrowed down to the switch and Ethernet cable.
If it's a problem related to the switch, it's possible that the switch blocks the port that Deco connected to. Before Decos establish the Ethernet Backhaul connection, the two Deco are linked both via Wi-Fi Backhaul and Ethernet connection, which may be regarded as a network loop by the switch. Therefore, the switch may block the Ethernet connection between the two Decos. You can try to check that and disable the network loopback detection on the port that Decos are connected to.

It seems to be faulty cable wire.
I replaced my cable in the wall and now it seems to work.
Thanks
Dekel.
P.s. is there a cable length restrictions?

Thanks SamyKn for the image of the new firmware Can anyone say what the image should look like if Ethernet backhaul is working? Instead of the WiFi symbol should there be something else? Even better if someone could post an image of a working Ethernet backhaul on the new firmware.

Mh that sucks, mine were like that and I was having issues with the backhaul.
