I upgraded Ubuntu to 20.04 and the setting for preferred WiFi frequency has disappeared. You can see a screenshot of the drop-down menu here:


How can I get this drop down menu back?

    Use nm-connection-editor.

The dropdown menu was removed from the UI (I could not find the reason).

But there is a work-around, by checking the manual of nm-settings:

  • Locate the targeted WiFi connection profile in /etc/NetworkManager/system-connections/nameofconnection.nmconnection
  • edit with sudo nano /etc/NetworkManager/system-connections/nameofconnection.nmconnection
  • Under section [wifi] add following entry
    • for 2.4 GHz only band=bg
    • for 5 GHz only band=a
  • save changes and connection should use the new configuration
  • 9
    Or run the command that is posted as a comment on the question (nm-connection-editor in the terminal)

To access the settings in a GUI execute nm-connection-editor in a terminal. Then choose your desired connection and click on edit.

Thanks. This did the trick for me!
