    Wireless Card Driver - Offline Solution Needed (realtek b822)

    I have recently installed Ubuntu 18.04 on my grandmother's HP Stream 14-ax010wm. The driver for the wireless card did not install during the OS installation.

    I cannot connect the laptop to a router with a hard line and need an offline solution. I currently have a second laptop to work a solution from.

    The information on the wireless card is as follows:

    Realtek Semiconductor Co., Ltd. b822
    PCI-ID: 14e4:4331
    Kernal Modules: r8822be

    What??

    14e4:4331 is the pci.id for a Broadcom device. Where did that come from? What does grandmother's computer really contain? Please run and post:
    Code:
    lspci -nnk | grep 0280 -A3
    In case it is actually the Realtek, also run and post the exact response to these commands:
    Code:
    sudo modprobe r8822be
    dmesg | grep 8822

    My apologies for the sideways image, not sure what happened there.

    Please copy and paste the terminal output into your post, enclosing between code tags. Make it easier for others to help you.

    ‘Required key not available’ means that you must turn off Secure Boot in the BIOS. It is a known bug with no fix quite yet.

    After doing so, reboot and the wireless should be working.
