Pi Zero 2 W has no wlan

Hardware Questions and Recommendations

Hi, i have 2 pi zero 2W. Bought within few weeks from same reseller.

Wlan with raspian works fine, but one of them has no wlan with openwrt.

I found a difference in dmesg:

The working one has:

brcmfmac: brcmf_c_preinit_dcmds: Firmware: BCM43430/1 wl0: Jun 14 2023 07:27:45 version 7.45.96.s1 (gf031a129) FWID 01-70bd2af7 es7

the nonworking has:

brcmfmac: brcmf_c_preinit_dcmds: Firmware: BCM43430/2 wl0: Mar 31 2022 17:24:51 version 9.88.4.77 (g58bc5cc) FWID 01-3b307371

I am using the same image on both devices. On the nonworking is the wlan not present.

Is there some way to enable it or exists different chipsets for wlan and some are unsoported?

From the dmesg

firmware is loaded

how about

ls /sys/class/ieee80211

on both devices ?

Hope you're not expecting great things from BCM based wireless.

what happens, if you swap the SD cards?
