Ubuntu – Ubuntu 14.04 Wireless not working: no network interface. Atheros [168c:003e] device

14.04atherosnetworkingwireless

I just installed Ubuntu 14.04.3 LTS after installing windows 10 in my new VN7-571G and the wireless is not working.
It never had: even during the installation it was not recognized.

I run a script to gather the data , which is here.

lspci -knn | grep Net -A2 output

03:00.0 Network controller [0280]: Qualcomm Atheros Device [168c:003e] (rev 20)
        Subsystem: Lite-On Communications Inc Device [11ad:0804]

The OS behaves like it has no wifi card. I do not see wifi settings in network settings

I'm not a linux power user, so I do not know what to do to solve the issue.
What should I do to make it work?

  • This device is supported in Ubuntu 15.10 with the latest updates.

    • You can get it work in Ubuntu 14.04 by installing kernel 4.2 and the updated firmware. Run in terminal:

      sudo apt-get install linux-generic-lts-wily
      wget https://mirrors.kernel.org/ubuntu/pool/main/l/linux-firmware/linux-firmware_1.157_all.deb
      sudo dpkg -i linux-firmware_1.157_all.deb
      
    • In Ubuntu 15.10 and later you only need to install the firmware:

      sudo apt-get install linux-firmware
      

    In both cases, reboot afterwards.
