Get wireless working on N1Phicomm N1 uses BCM4345/6. The driver for that chip should come with kernel and needs no extra steps. It’s the firmware that is missing.
Hence the firmware should be installed first (from non-free repo):
1 apt install firmware-brcm80211
But that only contains brcm/brcmfmac43455-sdio.bin. For the chip to work, it also needs a file named brcm/brcmfmac43455-sdio.txt:
123 [Sun Jan 13 00:00:00 2019] brcmfmac: brcmf_fw_alloc_request: using brcm/brcmfmac43455-sdio for chip BCM4345/6[Sun Jan 13 00:00:00 2019] usbcore: registered new interface driver brcmfmac[Sun Jan 13 00:00:00 2019] brcmfmac mmc1:0001:1: Direct firmware load for brcm/brcmfmac43455-sdio.txt failed with error -2
From a question on askubuntu, this file could be obtained from khadas’s GitHub.
After putting the file into /lib/firmware/brcm/brcmfmac43455-sdio.txt, and enable the wlan0 by adding configs to /etc/network/interfaces.d/wlan0:
12 allow-hotplug wlan0iface wlan0 inet dhcp
The wirelress finally appears:
