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

14.04 networking wireless atheros

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.

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?

  Just one thing. The upload speed through the wireless card is much smaller (50 mbps) than the upload speed through the ethernet card (220 mbps)...

Replying to you using the wifi connection now. Great work. Noticed the touchpad scroll is not working now. Can it be related?

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

@Pilot6 They released the fixed firmware. Could you reply to askubuntu.com/questions/697448/… ?

It is not only a firmware issue. This is also a kernel module. You'd better asked a new question.

Uninstall the module by sudo dpkg -r ath10k-dkms and follow the updated answer.

It has chosen the language automatically, I guess. I didn't notice that ;-)
