  • Please edit your question to show the exact response to the terminal command: sudo modprobe wl Welcome to Ask Ubuntu. (Secure Boot??) – chili555 Apr 08 '21 at 20:15
  • @chili555 question edited, I add sudo modprobe wl and mokutil --sb-state logs – Zeroone Apr 10 '21 at 10:52

The links you posted in your question suggest that you have tried several different packages and that, evidently, none of them are properly working. Let’s do some housekeeping and start fresh. With a temporary working internet connection by ethernet, tethering or whatever means possible, please run the terminal commands:

sudo apt purge broadcom-sta-dkms
sudo apt purge broadcom-sta-source
sudo apt purge broadcom-sta-common
sudo apt purge bcmwl-kernel-source

If some are the packages are not installed and therefore not removed, that’s fine; just proceed to the next step.

sudo apt update && sudo apt -y upgrade
sudo apt install -y bcmwl-kernel-source

Reboot.

Is there any improvement?

Edit: In our chat, we found that there were two additional wireless drivers installed. This is a possible explanation for the cfg80211 errors upon attempting to load the Broadcom driver wl.

We removed them both and rebooted. Your wireless was then working as expected.

  • Not working, i got this in log while sudo apt update && sudo apt -y upgrade: E: The repository 'cdrom://Ubuntu 20.04.2.0 LTS _Focal Fossa_ - Release amd64 (20210209.1) focal Release' does not have a Release file. N: Updating from such a repository can't be done securely, and is therefore disabled by default. N: See apt-secure(8) manpage for repository creation and user configuration details. while this commad sudo apt install -y bcmwl-kernel-source i got this line in log: modprobe: ERROR: could not insert 'wl': Invalid argument – Zeroone Apr 10 '21 at 15:00
  • In Software and Updates, please disable the CDROM as a source and try again. https://i1.wp.com/itsfoss.com/wp-content/uploads/2015/02/CDROM_Error_Update_Software_Sources.jpeg?resize=597%2C468&ssl=1 – chili555 Apr 10 '21 at 15:08
  • I disable CDROM and command sudo apt update && sudo apt -y upgrade work's fine, without any errors, but sudo apt install -y bcmwl-kernel-source again throw ERROR line modprobe: ERROR: could not insert 'wl': Invalid argument and no wi-fi again :( – Zeroone Apr 10 '21 at 15:51
  • May we please see: sudo dpkg -s bcmwl-kernel-source | grep Version We hope to see 6.30.223.271+bdcom-0ubuntu7. If that is what you do see, then show us a paste of: cat /var/lib/dkms/bcmwl/6.30.223.271+bdcom/5.8.0-48-generic/x86_64/log/make.log Paste it here and give us the link: http://paste.ubuntu.com – chili555 Apr 10 '21 at 19:41

  • How about: sudo dpkg -s bcmwl-kernel-source | grep Version Is this xx-0ubuntu7 or which? – chili555 Apr 10 '21 at 20:48

  • I followed these instruction but then got an error about the Kernel headers not being installed, so I did sudo apt install linux-headers-generic then it built and signed the bcm driver (I have secure boot so signing is needed). All working now. Perhaps edit to include making sure headers are installed? – Rodney Feb 23 '22 at 00:18
  • This worked for me in Ubuntu 22.04, thanks! – hrunk Mar 16 '23 at 17:22
