I was thinking about buying some smart devices like lights and such but I know the security for these devices can be subpar.

So here is my plan:

Wi-Fi Router A - for personal pc, phones, slave server, ect.

Wi-Fi Router B - for smart home devices.

Modem with 2 or more lan ports.

Problem:
The 2 routers are to keep the devices on separate networks. Problem with this is I can't find a modem that allows 2 or more devices to be connected via lan ports. The ones I'm finding that do have more than 1 lan port are 1 open and the rest bonded. Unless the modem is also a Wi-Fi router. But to me it seems if I condense Wi-Fi router B with a modem it could create an opportunity for man in the middle attacks for router A being that's it's plugged into the condensed router B/modem combo.

Thoughts, ideas, the modem I'm looking for?

Thanks.

Your problem is not a modem with 2 lan ports...you can just put a small switch on it....the problem is you only have a single IP address from your ISP.

Some ISP will sell you multiple but it tends to not be cost effective.

If the smart home devices do not need access to the internet just use a separate router and not hook the wan port up.

If you need internet then I would make the main router/modem connect to the smart devices and use a second router plugged into the first for your other stuff. The stuff behind the second router will treat your main network as the internet so it will be as secure any standard internet connection.
