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.

Is the 3th deco using ethernet backhaul? It should visible in the app
And is the powerline adapter on the same electrical phase as the recieving powerlineadapter?

@Smartmove Sounds like the problem is weak powerline links.
If you have the option, you can re-use coax wiring in the residence to get wired ethernet, see this article: https://evenroute.com/networking-coax-option
It is much more reliable than powerline.

@TP-Link Deco , I'm having major issues with setup.
Is there something wrong with my setup? My Deco M5 cannot connect to the internet. Please help.

@TP-Link Deco Hello, I have some X60 et M9plus and want to use them all as AP with a wired network (ethernet backhaul), using this configuration:
- One Netgear switch
- Internet Router providing DHCP connected to the switch
- Each Deco is wire-connected to the switch (in AP mode)
Question: what is the role of the "MAIN" Deco?
Does it handle all network flows from wifi devices connected to slave Deco, or is it just a role of the Deco network managemement (coonfiguration, statistics, etc.)? I guess that no, but to be sure.
Thank you

I don't know for sure, but I have a strong inkling the Master role in AP mode is primarily 'mesh management' ... and it may also be the "keeper of statistics" which are reported by the app; that is, the app "asks" from the Master Deco, and it supplies the info (which it may do by using the backhaul to query each of the other Decos, or it may have been keeping those statistics continually updated all along -- although they could have also implemented distributed copies of that stats to each Deco, and the app's client connected-Deco could supply its copy ... but I doubt it's that sophisticated at this point). I suspect the Master is also probably the primary role in adding / removing new Decos to the network (which it definitely would be doing in non-AP mode as well) -- that is, it provides the network configuration defaults to a newly-joining node. Which is why I recommend setting up a new node physically near the Master node (so setup will be smooth & quick), then moving it to its final location.
I'd be really surprised if data traffic was forced through the Master (when it is not physically configured on the network as a router); that would be sort of counter to the whole design of a mesh.
Only the TP-link/Deco architects/developers know for sure.
FYI: Your setup is similar to mine (substituting X20/3600 for M9's; one of my X20's uses wireless backhaul)

Hello
I have connected a lan cable (yellow) directly
From the master to the lan point and linked to the slave deco. This is for the eternet backbone. Not usinh switches.
But it doesnt detect the lan connection.
Any configuration that i need to do using the app?

@Chriskoh Since it doesn't appear that you are using this as a router device, you should change the "Operating Mode" to AP (Access Point).
On the default screen (Overview), tap the "More" at lower right, then "Advanced". "Operating Mode" is shown there: Tap that to see the next screen and select "Access Point" instead of the default "Router". Once that configuration change is saved and the device reboots, that 'mode' will be "inherited" by each subsequent Deco you add to the mesh.

Hi, I have a deco x60 and I'm using the ethernet backhaul feature. Works great however I have an extremely high latency problem now, around 200 Ms to my server compaird with my old router from 2007 that had 10-40 Ms. Is this some kind of software issues

Hi, I've set up my network as follows (in what I would understand is the Star Newtork described in https://www.tp-link.com/us/support/faq/1794/), configured the network with all Decos wirelessly and then plugged the ethernet cables into the second and third, but when the two slaves are connected I completely lose internet connection:
Modem > Deco M5 (Main)
Deco M5 (Main) > Apple Time Capsule (Bridge mode)
LAN 1 port on Apple TC > Deco M5 (Second)
LAN 1 port on Apple TC > Deco M5 (Third)
Deco system set up in Router Mode.
Any thoughts on what might be wrong?
Thanks.
Chris
