Switch and Router Connected Directly to ONT
Community Power UserYou cannot connect LAN ports to each other between routers. It will mess things up. If you have the R7000 first, the Optik TV boxes are not likely to work.
Recommended setup:
ONT Port 1 -- WAN of T3200M --- LAN4 connected to WAN on R7000
If the R7000 has an IP of 192.168.1.1, that will definitely cause an IP conflict. The T3200M uses the same subnet (192.168.1.x). You are better off putting the R7000 behind the T3200M and change the subnet on it to something different like 192.168.10.x. so it won't conflict. You may have to disconnect it from the T3200M in order to reconfigure it.
The only other thing you could do is:
ONT --> Switch --> WAN on T3200
|
+------> WAN on R7000
Is LAN to LAN for routers not a thing? I'm doing it right now from LAN3 of the T3200M to LAN1 on the D-Link which is also a router but I've switched the DHCP server off and assigned it a static IP. It communicates fine with the T3200M and my PiHole server.
The only reason I had the R7000 in the garage to begin with was because whoever wired the house when it was built did one Ethernet run only in the house which terminated behind the TV on the main floor. The only way to get the recommended setup would be to wire the switch to a LAN port on the T3200M and just drag the cable across the floor which I don't really want to do.
You can use the AP's and swich interchangably for Devices A, B and C in the diagram below.
Make sure the routers are set up properly for AP mode (set a static IP outside the T3200M DHCP range and DHCP turned off). Refer to the manufacturer's instructions as they might be a bit diffferent for each one.
