Hello Maks I tested the following: 1. Copy file brcmfmac43430-sdio.AP6212.txt from upstream to lib/firmware/brcm 2. Create symbolic link named brcmfmac43430-sdio.sinovoip.bpi-m3.txt to the AP6212-file 3. Create symbolic link named brcmfmac43430-sdio.sinovoip.bpi-m2-ultra.txt to the AP6212-file After that, the wlan0 interface is available and scanning of the WLAN-ESSIDs works. Please either do it like described above or add the files directly instead of the symbolic links. Best regards and thank you for the great support. Bernhard
