@onepiece said in Creating VLANs and subnets (and SSIDs) using pfSense:

Do most modern APs allow multiple SSID transmissions using separate subnets simultaneously?

Proper APs usually do, but using a router as an AP won't. Just read the specs to see what an AP can do.

I have a Unifi AC-Lite AP, which supports multiple SSIDs and VLANs, as did a TP-Link AP I used before.

BTW, some people here like the Unifi APs.
