I'm looking for a router, which has a built-in modem one that can have two wifi networks completely isolated from one another.
I'm hoping to isolate various appliances, e.g. a refrigerator connected to wifi X should have no way to interact with my personal laptop connected to wifi Y over LAN.
The other major requirement, (which I'm pretty sure I'm not describing well enough) is that the router support optic fibers as the one provided by my ISP.
Let me know if there is more info I can share.
