    WiFi card not working with Lenovo Z50-75

    I just bought this laptop and tried to install Ubuntu 14.04.3. The installation went fine, but the wifi card is not detected. This is the first time something like this happens to me, so I have no idea how to debug the issue, let alone how to fix it. Googling didn't help, so I turned to the forum. The output of wireless_script is below. Any help would be much appreciated. Thank you!

    Code:

    Re: WiFi card not working with Lenovo Z50-75

    Code:
    sudo apt-get install build-essential linux-headers-$(uname -r) git
    echo "options ath10k_core skip_otp=y" | sudo tee /etc/modprobe.d/ath10k_core.conf
    wget https://www.kernel.org/pub/linux/kernel/projects/backports/2015/09/03/backports-20150903.tar.gz
    tar -zxvf backports-20150903.tar.gz
    cd backports-20150903
    make defconfig-ath10k
    make
    sudo make install
    git clone https://github.com/atondwal/ath10k-firmware.git
    sudo cp -r /ath10k-firmware/ath10k/ /lib/firmware/
    sudo cp -r /lib/firmware/ath10k/QCA6164/hw2.1 /lib/firmware/ath10k/QCA6174/
    Reboot

    If you have other wireless cards that you might want to use(USB dongle) use
    Code:
    make defconfig-wifi
    rather than
    Code:
    make defconfig-ath10k
    in step 6 above. I imagine you manually loaded ath9k thinking it might support this device

    Hi jeremy31,
    thank you very much for your help, your sequence of commands worked.
    Yes, I had tried to load ath9k because I thought it was the module for atheros cards, I wasn't aware of the existence of a newer version (which is not part of the linux kernel yet, apparently).
