在尝试烧录openwrt,烧录之后 ifconfig -a 看不到wlan0,官方对此情况有说明:

操作命令为:

mkdir wifi-firmware
cd wifi-firmware
# Pi 3B+ and 4
wget https://github.com/RPi-Distro/firmware-nonfree/raw/master/brcm/brcmfmac43455-sdio.bin
wget https://github.com/RPi-Distro/firmware-nonfree/raw/master/brcm/brcmfmac43455-sdio.clm_blob
wget https://github.com/RPi-Distro/firmware-nonfree/raw/master/brcm/brcmfmac43455-sdio.txt 
sudo cp *sdio* /lib/firmware/brcm/
cd ..
