    Hi there.
    Clevo P670HS-G is my machine. I run Linux mint 18.1.
    When I updated my box I suddenly lost the wifi.
    It was a mainline update.
    It just disappeared from the Networks Connection...
    So how can I get it back? Any backports or so?
    Any help would be very much appreciated!


    Regards
    Mikael

    I would restore from before the update and see if it's still there.

    Find out what driver versions System76 uses, a Clevo reseller for Linux.

    JeremyB on the great Mint forum.
    This should work as I think the 4.10 kernel may break the Nvidia driver


    CODE: SELECT ALL

    sudo apt-get update && sudo apt-get install git build-essential linux-headers-generic
    CODE: SELECT ALL

    git clone https://git.kernel.org/pub/scm/linux/kernel/git/iwlwifi/backport-iwlwifi.git -b release/LinuxCore28
    CODE: SELECT ALL

    cd backport-iwlwifi
    CODE: SELECT ALL

    make defconfig-iwlwifi-public
    CODE: SELECT ALL

    sed -i 's/CPTCFG_IWLMVM_VENDOR_CMDS=y/# CPTCFG_IWLMVM_VENDOR_CMDS is not set/' .config
    CODE: SELECT ALL

    make -j4
    CODE: SELECT ALL

    sudo make install
    Reboot

    If you update your kernel to a newer 4.4 kernel you will need to
    CODE: SELECT ALL

    cd backport-iwlwifi
    CODE: SELECT ALL

    make clean
    CODE: SELECT ALL

    make defconfig-iwlwifi-public
    CODE: SELECT ALL

    sed -i 's/CPTCFG_IWLMVM_VENDOR_CMDS=y/# CPTCFG_IWLMVM_VENDOR_CMDS is not set/' .config
    CODE: SELECT ALL

    make -j4
    CODE: SELECT ALL

    sudo make install
    Reboot
