Using Eero with existing 1 x Modem/Router Combo and 2 x Routers
I'm thinking about adding an Eero (Double-NAT) to my existing network (that somebody set up for me 1-2 years ago). My current network looks like this:
Internet ---> Modem/Router Combo (3rd floor - SSID_3) ---> Router2 (2nd floor - SSID_2) ---> Router1 (1st floor - SSID_1)
As you can see, all of these routers broadcast different SSIDs from each other (SSID_1 for 1st floor, SSID_2 for 2nd floor, SSID_3 for 3rd floor).
After reading this Eero help article, I'm thinking about double-NAT-ing my Eero with the current setup. So I'm thinking about changing the network to this:
Internet ---> Modem/Router Combo (3rd floor - Bridge mode - PPPoE) ---> Eero (3rd floor - SSID_3) ---> Unmanaged Switch (TP-Link) ---> Router2 (2nd floor - SSID_2) ---> Router1 (1st floor - SSID_1).
What I'm planning to do is putting the Modem/Router Combo from the ISP to Bridge Mode, and run Ethernet from that Modem/Router Combo to the Eero. Then I would run Ethernet from the Eero to an unmanaged switch (8 ports - 2 ports connecting to 2 x PCs).
From my unmanaged switch, I would use another port to run Ethernet to Router2 (2nd floor - SSID_2), and again run Ethernet from Router2 (2nd floor - SSID_2) to Router1 (1st floor - SSID_1).
Would this setup work? Please let me know what you think.
Ideally you'd replace Router2 and Router1 with eero. With three of them, you can use the same SSID throughout the house.
My setup (with double NAT, I can't put the ISP router in bridge mode):
Internet ---> Modem/Router Combo ---> eero ---> switch ---> 2nd eero (wired) + some locally wired PCs
A third eero connects to the main eero via wifi (I don't have a wired backhaul for it) but you can connect it to the unmanaged switch directly.
The key is that the modem/router does not go into the unmanaged switch but only into the eero and the switch connected to the other port of the eero. This way all the DHCP for your local network is handled by the eero.
