    Ubuntu Budgie 20.04 new install No wifi adapter found

    Hi,

    I've installed a brand new Budgie 20.04 LTS but I keep getting this: No wifi adapter found. I've already tried a dozen solutions found on the Internet before coming here, but with no success thus far.

    I tried this too: https://ubuntuforums.org/showthread.php?t=2214110

    I've installed the distro in parallel to Windows 10 (wifi works there just fine). Laptop: HP Pavilion (some old crap from 2015).

    I reinstalled thrice now - with 3rd party software and without. Nothing.

    Any clue how I could resolve this bitch of an issue?

    I'm starting to think that this is some yet another unique case, although I'm not vain at all and I'd rather not be unique in this case

    It's not supposed to fix anything; it's supposed to produce a diagnostic report that you post so that we can see and then propose a solution. Please post the report.

    What is the exact response to the terminal command:

    Code:
    sudo modprobe wl
    ...after you've disabled Secure Boot in the BIOS/EFI?

    Hi again, once I disable secure boot, the wifi seems to work. The qn is: can it be fixed with secure boot enabled?

    There's no response to sudo modprobe wl, and I mean I type it, press enter and the console just shows another empty command line.
