Use a direct cable comparison to narrow the fault to the intermediate switch path without disabling protections blindly.

You do not need Ethernet in every room to benefit from wired backhaul. Deco supports a mixture of wired and wireless satellite connections. The important step is understanding which segments use each method and whether the remaining wireless paths are healthy. Identify rooms with tested Ethernet sockets and note where they connect. A wall plate without a known live upstream port is not yet a usable backhaul. Confirm the network's operating mode before choosing the switch arrangement.
Read the full guide and sourcesWhen Deco runs in Router mode, the main unit separates its upstream internet connection from the network it manages. A switch used for satellite backhaul belongs on the main unit's LAN side. Treating every available Ethernet socket as equivalent can create an incorrect topology. Write the order as internet gateway, main Deco, LAN switch and satellite Decos. TP-Link's wiring guidance places wired satellites behind the main Deco in Router mode. Avoid connecting them to a switch that bypasses the main unit on its upstream side.

The BE25 version covers 2.4 and 5 GHz with two 2.5 Gigabit ports; the BE63 adds 6 GHz and lists four 2.5 Gigabit ports per unit. At the main router, one port serves the upstream connection. At a wired satellite, one may serve backhaul. Write down how many physical connections remain for a desktop, television or storage device. Extra ports can avoid a separate switch where space is limited.
Read the full guide and sourcesConnecting a television or console to an extender's Ethernet port can be useful, especially when the device's own wireless adapter is weak. However, if the extender connects to the router over Wi-Fi, the stream still depends on that wireless backhaul. Write the sequence as television, cable, extender, wireless link, router and internet. TP-Link describes this Ethernet bridge function on supported extenders. The cable changes the client-facing segment; it does not replace the radio connection between the extender and router.
