Hi everyone, hope you're doing well!

I recently purchased a DECO S7 AC1900 kit with three units for my office. I set them up in Access Point mode, using two units connected via Ethernet cable and the third one via Wi-Fi (wireless backhaul).

However, after configuration, the Deco app shows that all units are communicating via Wi-Fi only, even the ones connected by cable.

Here’s the current setup:

• The Decos are connected to a 24-port Layer 2 unmanaged switch;

• The switch receives internet from my ISP’s modem/router;

• All Ethernet cables were tested and are working fine;

• The system is properly configured in Access Point mode.

As a test, I brought the Decos home and connected them directly to my ISP router (which has 4 LAN ports). It worked perfectly — the Deco app showed that the units were using wired backhaul.

Has anyone experienced a similar issue? Could it be a limitation of the unmanaged switch? Is there any additional configuration required to make the wired backhaul work properly?

Any help is greatly appreciated!
