    No WiFi adapter found in Ubuntu 18.04, HP Laptop

    I've installed my Ubuntu 18.04 with minimal installation mode with keeping the option to install WiFi drivers along. But still I couldn't use the WiFi, since the setting is showing that there is no WiFi devices found.
    wireless-info.txtTried most of the solutions mentioned in forum but still can use the WiFi.

    unfortunately it still can't find any WiFi.
    Did you install any new packages based on the link I referred you to? Did you try a reboot? Is the driver loaded?
    Code:
    lsmod | grep wl
    If not, is there any clue if you try to load it?
    Code:
    sudo modprobe wl
    Is the wireless switch, sometimes referred to as Airplane Mode, set to enable or disable wireless?
    Code:
    rfkill list all
