I have been using Ubuntu on a Thinkpad for a while, and while upgrading kernels in Bionic Beaver, the drivers seems not to be working anymore: I have tried every drivers available (br-4, brcm-brfmac, linux-headers etc...) and I can't find the problem. I'm not a tech genius but I have followed every detail (except for the card, which is unregistered) to solve this issue detailed here... Installing Broadcom Wireless Drivers

So far I have tried the following kernels: b43, brcmfac, bcmwl-kernel-source.

Please let me know if you have any idea on how to diagnose the problem or repair it?

  • Your specific device is not listed in the usual Broadcom answer. I suggest that you try: sudo apt install bcmwl-kernel-source and reboot. – chili555 Jun 11 '19 at 13:03
  • @chili555 I've already tried that option, it didn't worked. when I try to reinstall it I get 'bcmwl-kernel-source is already the newest version (6.30.223.271+bdcom-0ubuntu4).' I have also tried to purge and reinstall it without success... – Jean Bouchart Jun 13 '19 at 15:22
  • Let;s check some diagnostics from the terminal: dmesg | grep wl and also:rfkill list all – chili555 Jun 13 '19 at 16:50
  • There is no blacklisting of the wifi card (the bluetooth is soft blocked if I understand the command right) – Jean Bouchart Jun 14 '19 at 18:06
  • It would be mush better if we could examine the actual messages. Please paste them here and give us the link: http://paste.ubuntu.com – chili555 Jun 14 '19 at 19:43
  • I have edited the message so everything is summed up in my question:dmesg | grep wl ##(no response)

    $ rfkill list all 0: tpacpi_bluetooth_sw: Bluetooth Soft blocked: yes Hard blocked: no 1: tpacpi_wwan_sw: Wireless WAN Soft blocked: no Hard blocked: no

  • Is there any error or warning if you do: sudo modprobe wl && dmesg | grep wl – chili555 Jun 15 '19 at 21:09
  • yes there is! :) printf("%d\n", 42); /* :~$ sudo modprobe wl && dmesg | grep wl [sudo] password for tachikoma: [ 3.507892] wl: loading out-of-tree module taints kernel.

  • Wow! brcmwl-kernel-source doesn't like your device at all! This usually reliable suggests that the correct driver is brcmfmac: https://wikidevi.com/wiki/Broadcom_BCM94356Z Please unload wl: sudo modprobe -r wl and load brcmfmac: sudo modprobe brcmfmac Then check the message log; it probably wants missing firmware: dmesg | grep brcm I suggest that you post the result here and give us the link: http://paste.ubuntu.com – chili555 Jun 17 '19 at 21:15
  • It worked!! partially but it did! 'https://paste.ubuntu.com/p/kQNkk8TsBV/plain/' – Jean Bouchart Jun 18 '19 at 20:44
  • Partially? Are you offered networks to connect to? Does it try to connect? Does it drop or what? You may as well: sudo apt purge bcmwl-kernel-source – chili555 Jun 18 '19 at 21:30

First, I suggest that you remove the incorrect driver wl:

sudo apt purge bcmwl-kernel-source

Next, blacklist the incorrect drivers b43 and ssb:

sudo -i
echo "blacklist b43"  >>  /etc/modprobe.d/blacklist.conf
echo "blacklist ssb"  >>  /etc/modprobe.d/blacklist.conf

Now, let's install the correct firmware:

cd /lib/firmware/brcm
wget https://gist.github.com/autofyrsto/f02435e1fa0ecb7e7be23d54b2d54177/raw/abf184185e48c3df9e8d477d31f08e242fc13afc/brcmfmac4356-pcie.txt
exit

Reboot and your wireless should be working.
