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.

Dear TP, I did check and it most certainly looks like the Deco units need to be in wireless range even when hard wired, if a unit is out of WiFi range it goes red and is reported in app as not connected. The thing is that this behavior is not consistent nor immediately. However, there surely is something fishy with the wired backhaul.
how is your network topology？ if the two decos are connected directly, the Ethernet back haul should be working even the wireless is disconnected.

Is there a solution to this issue yet? I have 4 decos main deck as router connected to internet modem, one wirelessly connected to the main deco and the other two connected via the Ethernet port. The ones connected via Ethernet is not working... ( they are not in the wireless range of the main unit.)I tried setting them up wirelessly first then moving them but it doesn't work. P.S all are updated to the latest firmware 1.1.1 build 20170614
Can you share your topology? If the two decos are wired into a switch, then the switch is wired into the router, the Ethernet back haul won't work.
The two decos should be connected to the main deco or not the router.

I have the exact same star pattern shown in the original post. However I am done waiting and ordered a competitors mesh system...
Good call!! I managed to email Amazon and they are allowing me to return my Deco M5 even though it was after the 30 days! Now there is a company with good customer service and support!!

Do I have to reconfigure the 2 APs (on the Deco App itself, aside from doing the physical start topology) if I want to have a wired backhaul (I originally set it up as daisy chained network)? Also, I currently have 192.168.0.x LAN, is there a way to change that to say 10.x.x.x network?
You only need to configure the first deco unit,the first unit is workingas router mode by default. After it's setup, you can change it into AP mode if needed. Then add the other deco units into the system via the app, then they will obtain the settings, from the first deco unit. http://www.tp-link.com/en/faq-1590.html
No matter the first unit is router or AP, the additional units act as RE (when connected wirelessly), or AP ( when hardwired to each other).
The Ip of the deco connton be modify. You can find more explanations from Frequent Asked Questions

Pls recommend me a smart switch brand and model which works on Deco Ethernet Back-haul.
Current try to use Old Dlink DSG-1005A Giga smart switch Ethernet Back-haul not working.
Direct Deco to Deco working fine. Planing to backhaul the rest deco with Homeplug soon. Pls advise...

I'm planning to buy a TP-Link switch but was wondering if you ever got backhaul working properly? I was using an old Buffalo router (with DHCP/NAT/configured IP) but backhaul wouldn't work consistently.
