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.

  • Replying to you using the wifi connection now. Great work. Noticed the touchpad scroll is not working now. Can it be related? – Makers_F Aug 14 '15 at 16:04
  • That was the solution I needed to make backports into dkms deb files, you have to copy the backports after running make deconfig-wifi or whatever individual module you want – Jeremy31 Oct 03 '15 at 22:13
  • Many, many thanks for solving problem with my lenovo e31-70 laptop in 3 mins :) – Lukasz Frankowski Oct 14 '15 at 20:21
  • @Pilot6 They released the fixed firmware. Could you reply to http://askubuntu.com/questions/697448/ubuntu-14-04-install-firmare-released-for-ath10k-pci ? – Makers_F Nov 13 '15 at 03:28
  • It is not only a firmware issue. This is also a kernel module. You'd better asked a new question. – Pilot6 Nov 13 '15 at 10:27
  • Uninstall the module by sudo dpkg -r ath10k-dkms and follow the updated answer. – Pilot6 Nov 13 '15 at 15:45
  • The current link to deb file gives 404 – Makers_F Feb 21 '16 at 08:53
  • @Makers_F Fixed. But it is obviously will be updated from time to time there. – Pilot6 Feb 21 '16 at 09:02
  • Is there a webpage which specifies the urls? – Makers_F Feb 21 '16 at 15:12

    @Makers_F Sure http://packages.ubuntu.com/search?lang=ru&suite=xenial&keywords=linux-firmware – Pilot6 Feb 21 '16 at 15:23
  • Here the english version http://packages.ubuntu.com/search?lang=en&suite=xenial&keywords=linux-firmware – Makers_F Feb 21 '16 at 21:23
  • It has chosen the language automatically, I guess. I didn't notice that ;-) – Pilot6 Feb 21 '16 at 21:26
  • I am running 14.04.4 LTS .This solution makes my computer 10 times slower.So I removed them from my machine.Again I can not see any wireless sign anymore in my machine – bhordupur Apr 10 '16 at 17:19
  • For me the Wi-fi had always worked earlier, and all of a sudden the 'Enable W-ifi' disappeared from the menu. I followed the above steps in the answer for Ubuntu 14.04 and my Wi-fi has started working again. Although one thing that I would like to bring to notice - While installing the 'linux-generic-lts-wily', I did get a Bad Status Error, but that was all, nothing has broken so far. I have been able to boot as usual and my Wi-Fi works. So @Pilot6 Thanks a Lot! – Abhishek Potnis Apr 20 '16 at 03:06
