Pi 4 and Pi zero 2 w can not see built in wireless nic.

[koaie]

Using the latest release, flash to a pi4/pi zero 2 w, you wont see the built in nic, help would be appreciated, I already checked and the PI4 driver is installed (firmware-brcm80211), any steps towards the right direction would be helpful, thank you.

wlan 0 is my AR9271 based card.
