Question Cannot find drivers for Qualcomm Atheros Device 0042


Hi everyone, thank you for helping me out.
Here is my problem. My Wifi doesnt work. I think its a problem with the drivers not installed. And when I go into the drivers updates there is nothing there. After some search on internet I found that others before me previously had the same problem with Qualcomm Atheros R48xx. The problem apparently have been resolved somewhere but all the links to the proper driver were expired. I also read that depending on the version of Qualcomm Atheros you have, it might not be the same driver.
I recently installed ubuntu 14 as the sole OS on my computer and have no internet access unless I am going to my friend place ( who live one hour away from me) It can take sometimes several hours before I reply but I always reply.

Thank you again.

Hi...

Welcome to the forum

EDIT: Try Emerson's solution (above) first before responding to my requests below. It might resolve your issue.

Thank you for the information and readouts. However, I'll need some additional and more detailed information. If you would, please post the entire results of these commands...

Code:
lspci -nnk | grep -i net -A2
Code:
lsmod
Code:
iwconfig
Code:
rfkill list
Also, if possible, please attach the results of this script using either of the two methods that work best for you.

Regards...

take a look at this

Wifi with Qualcomm Atheros Device [168c:0042] (rev 30) on Linux Mint


it has a git address, within the instructions on how to install them on mint, for the drivers maybe just maybe you can use them and go from there.

as you have to be in a different box. just go into a terminal cd to a USB stick then type

Code:
git clone https://github.com/kvalo/ath10k-firmware.git
that way all ya got a do is use that and plug it into your wifi 'less box then copy them to where you want them to compile or what ever needs to be done with them.

if need be of course.

its a good link I just tested it. btw

contents:
Quote:
08:35 PM ~/temp/ath10k-firmware$ ls
LICENSE.qca_firmware QCA6174 QCA9887 QCA99X0
Makefile QCA9377 QCA988X README.md
mod:

I just found this, haven't check it though

Atheros Linux wireless drivers
This page documents all Atheros Communications Linux wireless drivers.

...

ah yeah you got a dig around in it you may just find the exact driver source code you need.

Thank you Everyone.

Wow, I was impressed on how fast this problem was resolved.
Emerson, the link you gave me contained the solution.
I installed the backports

sudo apt-get install build-essential linux-headers-$(uname -r) git
echo "options ath10k_core skip_otp=y" | sudo tee /etc/modprobe.d/ath10k_core.conf
wget https://www.kernel.org/pub/linux/ker...0151120.tar.gz
tar zxvf backports-20151120.tar.gz
cd backports-20151120
make defconfig-wifi
make
sudo make install
git clone https://github.com/kvalo/ath10k-firmware.git
sudo cp -r ath10k-firmware/QCA9377 /lib/firmware/ath10k/
sudo cp /lib/firmware/ath10k/QCA9377/hw1.0/firmware-5.bin_WLAN.TF.1.0-00267-1 /lib/firmware/ath10k/QCA9377/hw1.0/firmware-5.bin


Thank you again,

Emerson, What is code tags?

This is how it looks with CODE tags, easier to read and separated from rest of post.
Code:
sudo apt-get install build-essential linux-headers-$(uname -r) git
echo "options ath10k_core skip_otp=y" | sudo tee /etc/modprobe.d/ath10k_core.conf
wget https://www.kernel.org/pub/linux/ker...0151120.tar.gz
tar zxvf backports-20151120.tar.gz
cd backports-20151120
make defconfig-wifi
make
sudo make install
git clone https://github.com/kvalo/ath10k-firmware.git
sudo cp -r ath10k-firmware/QCA9377 /lib/firmware/ath10k/
sudo cp /lib/firmware/ath10k/QCA9377/hw1.0/firmware-5.bin_WLAN.TF.1.0-00267-1 /lib/firmware/ath10k/QCA9377/hw1.0/firmware-5.bin

Sorry to just jump in, but I have had the same problem with the same wifi card, with my new install of mint kde.
I am too new to linux to understand the link in Emerson's post.
Could someone please explain how to accomplish the solution in terms a mentally retarded 8 year old could understand?

To Ho-di-ho

You need to open a terminal first
Then log in as root. The code will be su or sudo
You will need to put your passeword in.
After you are logged in, you type one line at the time and press enter between.

Come back if you have more questions

Code:
The HTTP 404 Not Found Error means that the webpage you
were trying to reach could not be found on the server. 
It is a Client-side Error which means that either the
page has been removed or moved and the URL was
not changed accordingly, or that you typed in
the URL incorrectly.
know your http errors or try googling them first

The link isn't broken in the post, but it is when you make a copy. The "..." means part of the address is left out.

Here is the full line broken into two lines to make it all show up. Just paste the two lines back together into one line when you try again. Good luck.
Code:
https://www.kernel.org/pub/
linux/kernel/projects/backports/2015/11/20/backports-20151120.tar.gz
