  • Let's start by identifying your wireless device. Please edit your question to add the result of this terminal command: lspci -nn | grep 0280. Welcome to askubuntu. – chili555 Sep 10 '15 at 13:43

Your Atheros wireless device 168c:0042 is not yet supported in the Linux kernel. Please see: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1484159

And also: http://ubuntuforums.org/showthread.php?t=2281584

From the last link:

Finally, until support comes along, I'd suggest an inexpensive USB wireless device. There are often threads here about working devices.
