wifi Qualcomm Atheros Device UNCLAIMED, Ubuntu 14.04 / 14.10

Asked by Răzvan

Hello everybody,

AS I can see around the forum, a lot of people have issues with Atheros wifi devices :( unfortunately I am one of them too...
I cannot use the WiFi interface as it appears Ubuntu includes no compatible driver.

Any help in getting this fixed is greatly appreciated!

Please check the logs attached to the following post for further technical details: http://ubuntuforums.org/showthread.php?t=2266083

Thank you!

What is the output of :

sudo lshw -C network ; lsb_release -a; uname -a

Use a wired connection (especially if the system is a laptop) to give the details as well as get fully updated.

Your wireless adapter is experiencing the following bug:


I suspect you will need to wait for the release of the v3.20 Linux kernel and then install the 3.20 mainline Ubuntu kernel when it is released at the following location:

Hi guys,

Thanks for the prompt reply! Greatly appreciated!

@Mark: I did came across that and also commented and specified it affects me too.
The reason I opened a new question is due to the fact that the models are different - at least this shows up in the generated outputs that you can find here:

@actionparsnip: please check the above URL with the output collected yesterday

Thank you once again for your involvement, have a great weekend!

The bugreport


is about the wireless chipset with following VendorID+ProductID

[168c:003e] (rev 20)

The wireless chipset in your Terminal output at


has the SAME VendorID+ProductID and the SAME revision number (rev 20) which is

[168c:003e] (rev 20)

So the wireless chipset is the SAME in both threads. The human readable model type is less reliable than the VendorID+ProductID combination. VendorID+ProductID (+ revision number) is the only information that matters.

So it is unnecessary to create separate threads about this in




when there is already a bugreport open about the same wireless chipset.

The subsystem name of your wireless device does not matter. It is irrelevant.

Hi Mark,

Thank you for the additional details. I am sorry if this question is of any inconvenience to you or others - it wasn't my intention.

From the sticky notes, and what else I have been reading around here, I didn't get the idea that the only important details are the ones between the first square brackets, so presumed that having a different subsystem ([105b:e08e] compared to the [1a56:1525] one in the bug), might represent a different case.

Anyway, I presume that is the case with the questions, to ask and get answers, so thank you again for answering my question.

Best of luck and hopefully we will manage to get a working driver for that card too.

Thank you.

Can you help with this problem?
