Ethernet backhaul between X50-PoEs not working
I have a TL-R605 v2 Internet Gateway, one LAN port of which is connected to a TP-Link Tl-Sg1016pe switch.
There are also 3 TP-Link Deco X50-PoEs connected to this switch via Ethernet (PoE), which are operated in access point mode.
So I currently have
Internet Gateway --> Switch --> 3x Deco
I'd expect this setup to work as per the manuals and my online research.
Unfortunately, the Decos always connect to each other via WiFi/Mesh instead of Ethernet backhaul (via the switch).
On the switch I tried disabling Loop detection, this resulted in no change at at.
As a side note: I also tried having the main deco connected to the R605 and the switch, but the other Decos still refuse to use the Ethernet.
Internet Gateway --> Main Deco --> Switch --> 2x Deco
What am I doing wrong?
Can I force the decos to use the Ethernet?
