Deco satellite loses Wifi connection when TP-Link switch is active
Hi there,
My current Mesh setup consists of the following:
- main Deco M9 connected to my ISP's modem/router on the living room, set to Access Point mode;
- a TP-Link unmanaged switch, model SG105, located on a bedroom at the center of the apartment, to which I have both the main Deco and a second Deco M9 connected via cable, thus enabling Ethernet backhaul;
- one Deco M5 placed on a different bedroom, which I want to connect to the network via Wifi.
Here's a diagram of the setup:

I am able to set everything up wonderfully as long as I don't connect the second M9 to the aforementioned switch. As soon as I do that - and I need to, in order to get extra Ethernet ports -, the M5 shows as disconnected on the Deco app.
This should be a pretty simple setup, I guess, but my limited knowledge on home networking is probably causing me to make some dumb mistake.
Can you help me figure out what's wrong, please?
Is is perhaps this particular switch model that is preventing the Wifi backhaul from happening on that second satellite?
Thanks so much in advance!
