In order to use pfSense as a wireless access point, you must meet the following prerequisites:
- Add a wireless card to your pfSense system that is supported by pfSense. You will likely want to consult the FreeBSD Hardware Notes first. You can find information about compatible wireless interfaces for FreeBSD 11.1 at: https://www.freebsd.org/releases/11.2R/hardware.html#wlan
- The wireless card must be detected by pfSense.
