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.

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.
