    Cannot find wireless NIC device model or a driver.

    Hello.
    I cannot find a device name for my wireless NIC installed in my HP laptop, as there is no driver installed and I wished to locate one.
    It is a fresh install of Kubuntu and the wireless NIC has never worked. Kubuntu 18.04LTS is of the latest version and I have generated a wireless-info.txt utilizing the script in the pinned post, and am willing to supply more information if needed.
    I will attempt to respond as promptly as possible to any replies.

    Thank you.

    First step, disable Secure Boot in BIOS/UEFI
    Then in terminal do
    Code:
    sudo apt-get install dkms git build-essential
    git clone -b extended https://github.com/lwfinger/rtlwifi_new.git
    sudo dkms add ./rtlwifi_new
    sudo dkms install rtlwifi-new/0.6
    sudo cp -r rtlwifi_new/firmware/rtlwifi/ /lib/firmware/
    echo "options rtl8723de ant_sel=2" | sudo tee /etc/modprobe.d/rtl8723de.conf
    Reboot
