    Meaning what? That it won't install? That it installs but won't modprobe? That it installs and loads but doesn't drive your device? That it drives your device but doesn't connect? Or...what?

    Please run and post:
    Code:
    lspci -nnk | grep 0280 -A3
    lsmod | grep wl
    sudo modprobe wl && dmesg | grep wl

    Hello Chili555 and thanks for the response,

    It means that wireless card is not found by system here are the outputs.

    Code:
    sudo modprobe wl && dmesg | grep wl

    Re: Broadcom-wl 19.04

    With a working internet connection by ethernet, tethering or whatever means possible, open a terminal and do:
    Code:
    sudo apt install firmware-b43-installer
    sudo apt purge bcmwl-kernel-source
    Reboot and let us see:
    Code:
    iwconfig
    dmesg | grep b43
    rfkill list all

              Power Management:off
    dmesg | grep b43
    Returns nothing.

    Code:

    Quite simply, we removed the incorrect driver and installed the firmware required by the correct driver.
