Adding a second WiFi to my network using qotom onboard WiFi

[intruder]

I am running pfsense on a qotom with builtin wireless. This’s was an upgrade from an older pc I was running pfsense on. My WiFi works fine as is. But I want to use the wireless in the qotom also with a different 3rd octet but still access my wan (internet). I have tried several different settings. I can get devices to connect to the WiFi but not get to the net. Any help would be greatly appreciated. Just some background I have a switch that has my network with an access point connected to it. It works fine. I am wanting to set up a secondary WiFi for certain wireless devices in my house. I will be adding a couple of more switches which I also hope to have the 3rd octet different to steerage my video, entertainment (computers and consoles), and cctv on different isolated networks but use the same WiFi. My qotom is 4 ports eth0 is my wan

Thanks.

AFAIK , it is not recommended to run "WiFi AP" directly on the pfSense.
While possible, it seems that there can be issues ,with the freebsd AP implementation.

It would be preferable to get a "cheap external wifi unit"

To use the built in wifi for access point, it needs to be in access point mode, which afaik isn't supported/doesn't work.
Doing it with an external ap connected to a lan port is a far far better solution overall.

If you've added the interface and clients can connect to it then check they are getting an IP address from dhcp correctly. If they are then you are probably missing a firewall rule or possibly an outbound NAT rule if it not in automatic mode.
