Today I updated from Ubuntu 18.04.something LTS to Ubuntu 20.04.1 LTS. My laptop no longer automatically connects to Wifi (hidden network), it worked "fine" before updating. Each time I turn on my computer or resume from sleep I have to go to Settings, then WiFi and click "Connect to Hidden Network…". To make things worse, after manually connecting, if I click on the cog icon next to my network on the available networks list, Settings window freezes completely, and I have to restart the computer in order to make the window disappear. Any idea how to auto-connect, like before the update?

  • Have you tried removing the saved wifi and then re-adding it after you upgraded? Oct 1 '20 at 23:07
  • Yes, the problem persists.

Installing the correct wireless drivers fixes the problem. Follow the instructions from this post (for Broadcom wifi cards).
