Some advice, quickset → avoid!
I’m assuming that you have need of multiple SSID/WLANS due to different types of users.
- secure home users
- untrustworthy IOT devices
- vid Cameras
- guest users.
All which may or may not require different subnets. If they are on their own subnet then they probably should be on their own WLAN.
The easy way to do this is via VLANs. ( by the way no need for capsman here, keep life simple ).

Hint: Tread WLAN interfaces same as etherportst! ( wireless ports etc.)
