For posterity, however, I have found that: - The WiFi card _is_ the =E2=80=9Cethernet=E2=80=9D device seen in =E2=80=98= ip address=E2=80=99. - The brcmfmac driver searches for the following missing files in the firmware directory: 1. brcmfmac43602-pcie.txt =20 This file can be found in the attachments of this thread [1], where others encountering this issue made it via reverse-engineering. =20 2, brcmfmac43602-pcie.Apple Inc-.txt 3. brcmfmac43602-pcie.Apple Inc-.bin Where is in my case =E2=80=98MacBookPro-12,1=E2=80=99= . =20 These files are indicated to be searched for and missing by dmesg [2], but I have no idea where these would be found. I=E2=80=99d = guess that some more =E2=80=9Cuser-friendly=E2=80=9D distros would ship them, = so I=E2=80=99ll start the search with their install images. Again, if the .txt file=E2=80=99= s licensing is OK, it should be in the libre kernel, I think? I=E2=80=99m going to try to write a package that includes these missing = files. If anyone has any recommendations of relevant mailing lists or resources for this problem, I would be very appreciative.
