ONT (lan port 1) --> Router 1 (wan port)
Router 1 (lan port 1) --> Switch (lan port 1)
Switch (lan port 2) --> wall plug --> Router 2 (lan port)
Switch (lan port 3) --> wall plug --> Router 3 (lan port)
Router 1 configured as gateway.
Routers 2 and 3 configured as "Connect Via: Disabled", with DHCP turned OFF.
Router 1 handles all DHCP and network monitoring for the entire network. The entire network is on a single subnet and you have no connectivity issues between any devices.
If this works, you can then look at bridging the WAN port and gaining an extra port for use.
Once you have tackled this, then we can look at WiFi. One at a time as i think you don't have the fundamentals sorted at this stage.
