WiFi is working on OPi3, but you need to manually tweak the firmware and reboot : mv /lib/firmware/brcm/brcmfmac43455-sdio.bin /lib/firmware/brcm/brcmfmac43455-sdio.bin-ORIG mv /lib/firmware/brcm/brcmfmac43455-sdio.txt /lib/firmware/brcm/brcmfmac43455-sdio.txt-ORIG cp /lib/firmware/rkwifi/fw_bcm43456c5_ag.bin /lib/firmware/brcm/brcmfmac43455-sdio.bin cp /lib/firmware/rkwifi/nvram_ap6256.txt /lib/firmware/brcm/brcmfmac43455-sdio.txt
