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.

Have you tried to connect the second Deco directly to the LAN port of the main one? Will it work in this case? If yes, it seems an issue between Deco and the switches. Try to change the management IP address of the switches for a check.
Need to clarify that you need to firstly set up the three units in the same network via the Deco app before you use the Ethernet Backhaul features.
Is simply changing the IP address sufficient (say to 192.168.0.3), or does the subnet (subnet mask?) need to be changed, as stated in Note 4 in the original post?

Ethernet Backhaul is a feature which makes it possible to wired the Deco units together.
Thanks to this feature, every two Deco units can be wired with an Ethernet cable. And Deco will prefer to transmit data between two units through the Ethernet connection, which is more stable and faster than Wi-Fi.
Here are two typical connection structures for Ethernet Backhaul:
Hi. I am about t purchase a Deco set, and want to check my understanding of the Ethernet Backhaul feature.
But firstly, Q1: Does the Deco system somehow ‘encourage’ devices to use the best Deco unit, e.g when moving around the house?
(With my current collection of routers/APs/extenders, my devices seem to hang on as long as possible to even the weakest of signals, before eventually changing to a much stronger one... often long after the throughput has dwindled to almost nothing!)
Then Q2: When configured as in the first post in this thread (either daisychain or star) rather the pure wireless mesh, will this feature still work - e.g. will devices still be actively encouraged/forced use the best Deco Wi-fi signal?
Thanks

Guest network works just fine under ethernet backhaul. I really fail to undertand these problems you guys are having. This setup is really as simple as it can possibly be.I run 3 Deco units. The primary one is connected to my modem via ethernet. Off of the second port of that Deco, I have an 8 port Netgear gigabit switch. Connected to that switch I have another 8 port gigabit switch (Yes, I know. But I have alot of wired connections). From there I have an ethernet cable which runs to the farthest room if my house connected to another 5 port Netgear gigabit switch. Off of that switch I have my second Deco, and a wired computer. My third Deco is running in pure wireless mode. I set them up all on wireless first, and then put them in the places I wanted them, and everything runs super. The oy quibble I have, is DHCP reservation is not always assigning the appropriate I.P. addresses configured, but I am sure I will get that figured out soon enough.Muggost wrote
@TP-Link, you should make an amendment to the frist post in this thread: you need to let your customers know that guest network does not work when running Ethernet backhaul.

No, guest network does not work fine with Ethernet backhaul. They do, in fact, not work at all, as stated by TP-Link customer service. See one of my other posts on this forum:Kienzlenator wrote

I can assure you that you are wrong. I have my system on ethernet backhaul and currently have 12 devices connected to my guest network that work just fine. I suspect that either you have yet to update your firmware, or you are a troll that does not actually own the system and are just here to complain. Either way, it seems this system isn't for you so I suggest you return it and buy a different system and leave those of us who happen to enjoy it to use the forums without your negativity.Good day.Muggost wrote

For internet this is fine, but what if I need my phone to connect to a device on my main network. Will the first Deco that's acting as router and NATing allow my phone to talk to my Sonos which is wired?
I guess I could do this :
eg, plug my wired devices into the first TP Link but then I would be double NATing and I suspect that somethings that require a connecting to a device from the internet would not work due to the double NAT, this would create an issue for gaming.
I cannot setup my router in bridge mode as its provided by Sky and it's not got many features.
Many thanks
Steve
