I just got a Macbook Pro 12,1 which comes with the Broadcom
14e4:43ba chip (output from
lspci -nn -d 14e4:).
What I've tried
First, I built the latest kernel (4.1.6) from source. According to this page, installing the
brcmfmac driver should work for that chip. I copied brcmfmac43602-pcie.bin to the
/etc/firmware/brcm directory, then added
/etc/modules, rebooted, and verified both that 4.1.6 was running and that
brcmfmac appeared in the output from
lsmod. However, wifi still seems not to work;
eth0: no wireless extensions lo: no wireless extensions
How can I get this wifi chip working?
