I am also on 20.04.1 and my wifi connection has never worked. I have BCM4312.
I tried all the steps above, but it did not work. It can detect if I am on airplane mode, but it does not switch to wi-fi. I have followed all the https://ubuntuforums.org/showthread.php?t=2214110 previous threads too. The Additional drivers, the Broadcom ones (device is not working). Using broadcom 802 does not allow me to select (I was able to select before between Broadcom, continue using manually, do not use device). At the moment it is set on 'do not use device' and it won't unselect from this option.
