yes so the chain looks like:
ISP (cable/DSL) -> Modem -> Router / AP -> Wifi devices
_Router (diff subnet) / AP -> IoTs / Cams
so your 2nd router simply is off the main. this is to “load balance” off the main router of the burdensome heavy LAN streaming.
Possibly a 3rd router/AP combo for just IPTV devices.
Main router used for VPN/work
Ideally isolating similar device clusters for better bandwidth/efficient session control/security.
Not sure what is ideal but using a single router for everything sure doesn’t seem to work. I’m already doing this with a consumer router/AP and a Unfi AP separating out my NAS network for greater control of access and speed.
Still working through things.
I also have separate subnet for IoT dev using 8266s what have you.
Yea, so my needs are little unusual and demanding. Not to mention my neighbors hate me since I’m broadcasting over 10 diff SSID’s
