OK

4G Box -> Asus Router (on DMZ) -> Main Mesh & Mesh Network (TP-Link Deco Wifi6 on passthru mode, not router)

Mesh antenna -> ethernet to Switch1 (cisco) -> Synology, renderer, TV and Oppo 105D

Control point on the Mesh wifi network

Then I introduced the Buffalo
Mesh antenna -> Switch1 -> TV and Oppo 105D and Switch2 (Buffalo) -> Synology and renderer on this second switch

I went back to switch1 only

3 days fine. Then the problem came back.

Also, I never had issue with the synology, always visible. It is only my Klimax which regularly dissappears (always been on same switch as Syno)

There is only one network. Nothing is connected to the 4Gbox (192.168.1.1) but everything through the router DHCP (192.168.73.x)

Synology like klimax have fixed IP adresses from the router, outside the DHCP range
