[Bug]: wlan0 not available with pwnagotchi but could be used with other OS

[Antoine1-byte]

What happened?

Describe the bug
Wlan0 is not available whatever pwnagotchi image is used

Steps to reproduce the behavior:

• Install pwnagotchi
• ifconfig

Expected behavior

• Expectation after installation is that when ssh the pwnagotchi, I shall have a wlan0 interface to get it working but only lo and usb0 are visible.

Screenshots

As you can see, the Pi Zero is properly identified via cat /proc/cpuinfo

OTP row 30 shows "30:009000c1" which I understood is the expected value

Environment (please complete the following information):

• different versions have been tested
• pi zero W 1.1

Additional context

• Strange thing is that if I install raspiOS 2025-05-13-raspios-bookworm-armhf.img the Pi Zero W is identified as a Raspberry Pi 3 Model B Rev 1.2 and that with this OS, wlan interface is working

I'm trying to fix this issue since couple of days, tried some "force_board_rev=" and other stuff but nothing is working.
Fact that with RaspiOS the wlan is properly working, my conclusion is that it is not link to hardware but somewhere in the software...

Thanks in advance for any tips you would have

You did install the 32bit image right?

Yes I did!

I had another Pi Zero laying somewhere and tested with this one: with the second one it is working...

So there is something wich is causing an issue with the 1st Pi0W I tried but fact than wlan is working with RaspiOS generate a bit of challenge to me.
I'd like to understand where is coming the issue...

The software has no issues, there is something about the hardware. What wifi chipset is it?

Hello, same problem with two boards of Pi Zero W V1.1, here is sudo dmesg | grep brcmfmac:

Any ideas?
