In case you have, just like me, come across the issue that Ubuntu 20.04 greets you with a ’no wifi adapter’ error message after running some updates, this here did the trick for me:

  1. Connect your laptop to the internet (either ethernet, your phone etc.).
  2. Run the following two commands in the terminal (hit Ctrl + t):

  • sudo apt-get purge bcmwl-kernel-source

  • sudo apt-get install broadcom-sta-source broadcom-sta-dkms broadcom-sta-common

Reboot and everything should be running smoothly again!
