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

  • In Software and Updates, please disable the CDROM as a source and try again. i1.wp.com/itsfoss.com/wp-content/uploads/2015/02/…

  • 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 :(

  • 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: paste.ubuntu.com
