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.

Hi, it is ok and there is more information:
1. The Deco units need to work under access point mode.
2. You could use our TP-Link management switch, like

I rund the M9 Plus in router mode and have a topology like this: modem - main M9 Plus (router mode) - port 1 [switch A] port 5 - port 1 [switch B] port 5 - port 1 [switch C] port 5 - M9 Plus.
Switches are TL SG-2009 and T1500G-8T.
My question is how I need to configure the different switches A through C.
I saw this guideline: https://www.tp-link.com/us/support/faq/2317/ but it does not specfically address these questions:
What VLAN-ID should I set for the main network? No. 2?
Should I set all ports 1 and 5 for all the three switches to untagged for main network no. 2 and the same ports 1 and 5 for all the three switches to tagged for guest network (VLAN-ID 591)?
Do I keep the factory presets in the switches: "Default VLAN" as No. 1 for all ports as untagged.
Thank you.

Hi, for the TL-SG2009, you mean TL-SG2008, right?
Could you please send an email to support.forum@tp-link.com with the following information:
1. A detailed picture of your network topology with the exact model number of the switch, and the connected port number.
Thank you very much.

Hi @TP-Link Deco ,
UPDATE 1: Sorry just to clarify when I mention that the IPTV is VLAN 600, this VLAN 600 is tagged by the ISP. What I need is actually untagging that 600 traffic for the IPTV box to be able to function. Thanks.
My current setup is a Triple X60 (with 1 unmanaged switch) using the following topology:
I would like to consider changing to Double X90 (with TL-SG105E) using the following proposed topology (without reusing any of the X60s):
May I get your advise on how the TL-SG105E should be configured if it is at all possible to fulfill this topology please?
For clarity, TV and NAS shall not be on special VLANs. Only IPTV requires the VLAN 600.
I understand that using a 3rd node just to serve the IPTV over VLAN works but this is out of my budget.
I must not reuse the X60s as these were loaned to me.
Please advise. Thank you.

Hi, the IPTV on the Deco could not work with a switch in between.
but if it is possible to adjust the location of IPTV box for a little bit, like this: It might work.
Otherwise, you might still get one more unit and it does not have to be X90, maybe a M4 or M5

Thank you for the prompt answer. This helps in my buying decision.
In that case, it would be nice if TP-Link allowed disabling Wi-Fi AP on specific Mesh node, so that the M4/M5 (as suggested) merely serves as bridge for the IPTV only.
