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.

Will the following infrastructure work:
Modem --> Main Deco ---> 8 Port Switch ---> 5 Port Switch ---> Slave Deco 1
---> TV Box
---> Computer
---> Nvidia Shield
---> 5 Port Switch ---> Slave Deco 2
---> TV Box
---> Computer
---> Nvidia Shield
OR
Do I need to go
Modem --> Main Deco ---> 8 Port Switch --> Slave Deco 1 ---> 5 Port Switch
---> TV Box
---> Computer
---> Nvidia Shield
--> Slave Deco 2 ---> 5 Port Switch
---> TV Box
---> Computer
---> Nvidia Shield
As long as one of these above setups works where the 2 additional rooms where I am installing the Deco still has the ability to have a couple hardwired ethernet ports I am good. I need the switches to work at full speed.
Let me know. If both work that is also great, but I am thinking only the first setup will work

I should think either would work. The cautionary tale I learnt was using the Main Deco behind a router (modem -> router -> main deco) in Router mode and not AP mode, I had to ensure no other Slave Decos were directly connected to the Router.

@SamyKn As per your description, all the units are working in AP mode. Then every Deco unit should obtain an IP address from the Router via DHCP. And the Router should display all the units. Regarding this case, we suspect it's more likely an issue on the Router.
@Blackhawk Both infrastructures will work as expected in either Router mode or AP mode.
@alex_dong Your infrastructure could work as expected as well. Just make sure the powerline connection could forward all the packets between Decos.

Part of my house has a very weak wireless signal. Will the following configuration work?
Modem>M9>ethernet-cable>P7#1>P7powerline>P7#2

So, is this wired connection is impossible right? I have to connect them together via cable?

It will work fine in AP mode!
I have connected 5 decoM5 to the router's ethernet in AP mode and it worked perfect!

Thanks for responses, but I do not have a router. What I like to do is to connect a M9 to the Internet modem because of its ZigBee capabilities and larger number of antennas. The house is large with four floors so to reach the farthest part I like to use the powerline capability of the P7, i.e. a daisy chain like this:
Modem>M9main>ethernet-cable>P7slave#1>P7powerline>P7slave#2
So the question is if the powerline backhaul of the P7 works in a daisy chain between two P7s

I purchased 2x Deco M5 3 packs (I need 4 and will have spares for future outdoor use). I have the same issues as everyone else on here and that is mainly due to that fact that all my current switches are D-Link so before I go out and spend another $200 (I live in Canada so are money sucks) I want confirmation from the TP-Link supports guys that this will work.
Here is what I want my topology to look like with full wired backhaul in mind:
- ISP Modem/Router set to bridge mode
- Deco M51 as main with port 1 wired to ISP modem:
- Deco M51 port 2 > TP-Link TL-SG1016D Switch (feed most of my wired distribution)
- Deco 2 > wired back to TP-Link TL-SG1016D switch
- Deco 3 > 2nd TP-Link TL-SG108 switch
- Deco 4 > 3rd TP-Link TL-SG108 switch
If I add more M5's I will also add additional TP-Link TL-SG108 switch to connect it
Please tell me this will work trouble free, thanks in advance

請問我的Deco 可以跟我原本的路由器WIFI做結合變成一個嗎?
如果可以該怎麼設定

Does it matter which port on the DECO we use to connect to the wired switch? And can we then hang another switch off the 2nd/3rd/4th deco and pass wired traffic to those devices?
