Due to licensing uncertainty, we do not include the firmwares for the wireless chips used in the Raspberry Pi Zero 2 W. To have working wireless, follow the instructions below. For people building their own images: mkdir -p files/lib/firmware/brcm wget -P files/lib/firmware/brcm/ https://github.com/RPi-Distro/firmware-nonfree/raw/bullseye/debian/config/brcm80211/brcm/brcmfmac43436-sdio.bin wget -P files/lib/firmware/brcm/ https://github.com/RPi-Distro/firmware-nonfree/raw/bullseye/debian/config/brcm80211/brcm/brcmfmac43436-sdio.txt wget -P files/lib/firmware/brcm/ https://github.com/RPi-Distro/firmware-nonfree/raw/bullseye/debian/config/brcm80211/brcm/brcmfmac43436s-sdio.bin wget -P files/lib/firmware/brcm/ https://github.com/RPi-Distro/firmware-nonfree/raw/bullseye/debian/config/brcm80211/brcm/brcmfmac43436s-sdio.txt Now build the OpenWrt image as usual, and it will include the firmware files in the correct location. For people using ext4 images: Write the ext4 image to the sdcard, then mount the 2nd partition and put the firmware files from the links above in /lib/firmware/brcm relative from the mount point where the partition is mounted. For people using squashfs images: Write the squashfs image to the sdcard, place it in the Raspberry Pi Zero 2 W, boot it and wait for the overlay filesystem to be created. Find the offset of the overlay filesystem in sysfs: # cat /sys/devices/virtual/block/loop0/loop/offset 25755648 Shut down the device, unplug the power and move the SD card to a Linux computer. Mount the 2nd partition of the sdcard as a loop device with the offset found earlier. sudo mount /dev/sdh2 -o loop,offset=25755648 /mnt/temp Put the firmware files from the links above in /upper/lib/firmware/brcm relative to the mount point where the loop device is mounted.
