Solution Ethernet Backhaul not working
This Article applied to:
All Deco models
There are several typical network layouts for Ethernet Backhaul:
Case 1
Case 2
If your current network topology is similar to one of them, please refer to the following troubleshooting suggestions:
1. Temporarily the switch and connect the satellite Deco to the main Deco directly. If the Ethernet Backhaul is active immediately, please check whether your network switch supports IEEE 1905.1 protocol or not. Refer to Q4/Q5 in the below FAQ for more detailed explanation:
General questions about Ethernet Backhaul feature on your Deco
2. If the switch is confirmed IEEE 1905.1 protocol supported, please leave the model number of the switch here.
3. If you are using the TP-Link switches, login to the web UI of the switch, go to Monitoring > Loop Prevention to Disable the Loop Prevention:
Case 3:
Note: It also works in both wireless router and access point mode
Please refer to the troubleshooting suggestions:
1. Change the Ethernet cable between the Deco nodes.
2. Swap the location of the satellite Deco nodes to confirm that the issue is not caused by a specific Deco.
If the issue persists, comment below with the following information:
--What kind of Ethernet cable do you use, like UTP Cat5e?
--How long is the cable?
In the meantime, the following beta firmware has optimized the Ethernet Backhaul feature on Deco.
Please also install the firmware first and check whether Ethernet Backhaul could be successfully created.

Hi, yes, you could connect the CCTV receiver via Ethernet cable to the satellite Deco.
The following layouts both work well:
main Deco---<cable>--satellite Deco---<cable>---CCTV receiver
main Deco---<wireless>--satellite Deco---<cable>---CCTV receiver
Thanks.

Hi,
I try to achieve the following situation:
Not only that, I want the wireless deco to be selective in the source it takes from as wired deco:
I've tried to set this up in both router and AP mode, but I cannot get it to work completely.
I get al satelites online in the router mode, both for the wireless deco's the incorrect source is chosen.
How can I get this to work?

@frinsr1 Hi, your current firmware might not support selecting the signal source yet and you could test the following firmware:

Hi,
I purchased the 3 pack X60 system and intended to use ethernet backhaul as my main connection to other nodes. My current setup is:
Modem (Internet source) >>> tp-link switch (sf1005d) >>> main deco x60 and 2 other deco x60 on 2nd and 3rd floor.
The problem is: 2nd floor deco connected through ethernet backhaul but not the 3rd floor deco.
I tested the ethernet cable, it works as it should though.
I have attached the details network tree below for better understanding.
Please advice me how to get all floors connect through ethernet backhaul.

@Hellgomes welcome to the community. May I know the model number of your network switch?
And if you have installed Deco App 3.0, Can I have a picture of your network topology as well?
Best regards.
juzkid, Hi, is your Deco X60 working on the access point mode as well?
Would it make any difference to connect Deco -T3 to another Ethernet port from TL-SF1005D?
And if possible, please switch the location of T2 and T3 to see whether it is always the same Deco that failed to get Ethernet backhaul.
Thank you very much.
Best regards.

@David-TP yes I changed x60 to access point already. I've tried other ports on x60 and on the switch and still no luck. I've also tried to move T3-Deco to T2 and it worked. Should that be the wiring problem? But I have another asus router, it still works as the main internet source for that router though.
is there a command or something to force deco using ethernet backhaul?

Hi, Thanks for the update. There is no command to force Deco using Ethernet backhaul. If the T3-Deco could use Ethernet backhaul somewhere else, I think it is very likely the wiring problem, especially when the wires are inside the walls.
And I am not sure what do you mean by "But I have another asus router, it still works as the main internet source for that router though", did this Asus router use to be put where T3-Deco is to supply internet for 3rd floor?
Thank you very much.
Best regards.
