unable to get BCM4360 [14e4:43a0] (rev 03) Broadcom wifi working (guide followed)

**luusac** · May 1st, 2019

I have been trying to get wifi working on a mac booting from Disco or Bionic livecds (from a multi boot usb stick) without success. There already seems to be a [restricted] driver listed in additional drivers which I have tried and failed to get to work, so have been trying via terminal, also without success. This is a tri-boot macbook, and before I broke my Ubuntu installation I had Wily installed (not live cd) running quite happily with wifi.
So, here is what I have tried via terminal:

Code:

it@it:~$ sudo apt-get purge bcmwl-kernel-source
…

Note, selecting 'dkms' instead of '/media/it/SharedDrive/dkms_2.6.1-4ubuntu1_all.deb'

It all seems to go ok, but no wifi adapter listed in the gui.

########## wireless info END ############

One thing that I did notice was that b43 and bcm43xx seem to be blacklisted as shown in wireless-info.txt

I can't find my thunderbolt ethernet connector, so I really want to get wifi running on the live cd before proceeding further. I have added the full wireless-info.txt and terminal outputs as attachments, but have truncated them slightly above.
thank you.

This is what resolved the issue for me (on a livecd boot of disco):

first:

Code:

dmesg |grep wlan

gives no output. But

Code:

sudo apt-get install dkms bcmwl-kernel-source
sudo modprobe -rf wl
sudo modprobe -vv wl

gives:
