Model: Deco X60   Deco X20  
Hardware Version:
Firmware Version: 1.2.5 Build 20240106 Rel. 2319

Hello,

 

I have a system set up with 5 Deco devices, configured in Router Mode.

 

4 Deco are X60, with Firmware 1.2.5 Build 20240106 Rel. 2319

1 Deco is X20, with Firmware 1.1.8 Build 20240119 Rel. 37701

26 port switch Cisco SG220-26 (loopback detection turned off)

 

1 X60 is used as the main one, connected directly to the modem on Ethernet port 1.

3 X60 can be connected via cable routed back to the switch (port 1 as well?).

1 X20 is too far and has strong wifi connection to one of the X60.

 

It's connected like this:

 

Modem -> Main Deco (X60) -> Switch

All other Decos ==WiFi==> Main Deco

 

I can't get the Decos to set up a proper Ethernet Backhaul as one would expect it to be.

No matter how and when I plug them to the switch, they won't all connect to the Main Deco (in a star pattern).

They either connect to each other, for example A -> B, and then all else remain in WiFI.

Or, one of the four connects to the Main Deco, and then all the rest remain in WiFi.

 

How I expect it to behave:

 

Modem -> Main Deco (X60) -> Switch ---> 3 X60 Decos ==WiFi==> X20.

 

I'm probably doing something wrong, but I can't figure out what. Is the switch not compatible?

Thanks to @Jasper97, this switch does not support IEEE 1905.1 which is required for backhaul to work.
