2 routers, 2 separate networks, 1 modem… how? (lemmy.ml)

Hey all, I was wondering if anyone could help me work out how to do this? Basically, I have a stupid number of smart devices and my router has become increasingly unstable. I want to have all my IOT devices on one router and reserve the other for priority devices like phones and PCs.

I plan to put my IOT hub on 2G only and my primary hub on 6G and 6e only to avoid 2G congestion.

Problem is, if I connect both my routers to my modem, only one can connect to the internet. I tried putting a network switch between the routers and the modem, no dice.

Does anybody know how I can have 2 separate networks using 2 separate routers on a single modem? Both require internet connection but they don’t need to be able to communicate.

Thanks in advance for any help people can give :)

I am guessing that the Modem needs a PPPoE connection? Otherwise two routers on a modem should work but with PPPoE it wont. It is probably also just about the WiFi connections? Then you can just configure the IOT router to not use PPPoE and plug it into the other router.
