    ubuntu 18.10 realtek 8723de not working

    Hi!
    iḿ kind of new to ubuntu, i have read and tried different forums and topics on how to get this wireless card to work.
    now i'm afraid i have installed and uninstalled so many things that i dont know where i'm at.
    laptop is hp and the card in question is realtek 8723de.
    is there anyone online to be able to guide me trough the procces of fixing this??


    Thanks

    Something like
    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/rtlwifi/
    echo "options rtl8723de ant_sel=2" | sudo tee /etc/modprobe.d/rtl8723de.conf
    Then check results for
    Code:
    mokutil --sb-state
    Secure Boot needs to be disabled, if it says mokutil not installed, just reboot, otherwise Secure Boot will need to be disabled in BIOS

    ~/Desktop$ sudo dkms add ./rtlwifi_new
    Error! DKMS tree already contains: rtlwifi-new-0.6
    You cannot add the same module/version combo more than once.
