I'm using acer e5-47G, I tried the instructions given by dr-cono in http://ubuntuforums.org/showthread.php?t=2300861&page=3 but http://filebin.ca/2LVgpjSgiT56/backp...-11-05.tar.bz2 is down so I cant wget the tar.bz2.

I have been trying to work this out for quite some time and I'm stuck because I do not have the hardware. You will need to test for us.

With a temporary working internet connection, by ethernet, tethered or whatever means possible, open a terminal and do:

sudo apt-get update
sudo apt-get install linux-headers-generic build-essential
wget https://www.kernel.org/pub/linux/kernel/projects/backports/2015/11/20/backports-20151120.tar.gz
tar -zxvf backports-20151120.tar.gz
cd backports-20151120
make defconfig-ath10k
make
sudo make install

Reboot and let us see:

dmesg | grep ath

@chili555, man your instruction saved my life, I thank you so much man! im a newbie in ubuntu (I only use ubuntu for programming, already practiced on VMware ), do you know that I installed ubuntu for I guess 10x++ in 1week... 3 nights for searching how the grub 2 to work 'coz im dual booting windows 10 and ubuntu 14, and another 3 nights for my wifi and almost gave up, I thank myself for having "No retreat no surrender" attitude XD THANKS!!! (Lesson learned "go directly to the forum, 'coz not all solution can be found on youtube and google") XD

Hi!

I tried following these steps on an Acer Aspire E15 (E5-573-32IT), but this doesn't help. I managed to get the same output on running these commands, but the WiFi still doesn't function.

Please find attached the output for running the "wireless-info" bash script. Could someone please provide some insight into how to proceed here?

Thanks in advance!

In dmesg, we see this:

Direct firmware load for ath10k/QCA9377/hw1.0/firmware-5.bin failed with error -2

The next step is:

sudo mkdir /lib/firmware/ath10k/QCA9377/
sudo mkdir /lib/firmware/ath10k/QCA9377/hw1.0

sudo apt-get install git
git clone https://github.com/kvalo/ath10k-firmware.git
cd ath10k-firmware/QCA9377/hw1.0

Hello, chili555! Thank you for your reply, this finally managed to get the WiFi working! Unlike most others with this problem, I don't much difference in speed between WiFi and Ethernet, and no intermittent loss of connection, either.

But, could you walk me through what you did here? In the previous steps, I had downloaded the latest kernel, manually selected the wireless driver from that, and installed it. I can't make out what this git command is downloading, and what we did after that.

Also, I wonder if there was some other driver I was supposed to install? Because, in some of the other folders, I saw some other folders already present (This was while I was tab-autocompleting the two sudo cp commands after the git clone). Particularly, in /lib/firmware, I noticed a folder called "ath6k" in addition to ath10k. Also, inside ath10k, there was a single folder, "QCA988X" already present, containing a folder "hw2.0", with it's own board.bin and firmware.bin files. Is this expected, or did I download the wrong files by mistake?

Thank you, once again!

Many Linux wireless (and other) drivers require firmware. This can be seen in the terminal command:

modinfo ath10k_pci

filename:       /lib/modules/4.2.0-25-generic/kernel/drivers/net/wireless/ath/ath10k/ath10k_pci.ko

As we saw in your message logs, the firmware was not present. The git repository is a well-known source for the firmware files. We simply downloaded them and copied the specific files needed to the correct location; /lib/firmware//lib/firmware/ath10k/QCA9377/hw1.0/.

Because, in some of the other folders, I saw some other folders already present (This was while I was tab-autocompleting the two sudo cp commands after the git clone). Particularly, in /lib/firmware, I noticed a folder called "ath6k" in addition to ath10k. Also, inside ath10k, there was a single folder, "QCA988X" already present, containing a folder "hw2.0", with it's own board.bin and firmware.bin files. Is this expected, or did I download the wrong files by mistake?

Perfectly normal. No worries.

There is actually an easier way to do this today and my answer will be a bit different in the future. I assume your wireless is working as expected, so there is no need to do anything further except enjoy!

Hello, again, @Chilli555!

Last night, Elementary OS updated my kernel to "3.19.0-49-generic". This broke the WiFi setup that you had helped me setup previously. I followed the same steps that you had outlined in this thread previously (beginning from downloading the backport from "https://www.kernel.org/pub/linux/kernel/projects/backports/2015/11/20/backports-20151120.tar.gz" till "sudo modprobe ath10k_pci". However, this time around, I receive this error on the last modprobe command:

modprobe: ERROR: could not insert 'ath10k_pci': Invalid argument

I tried searching around for some solutions for this message. One post (on which you had participated) suggested changing the version number of the backport, but I don't know if that would work. After all, I'm backporting the same kernel module that I did the first time around, and it had worked at that time!

Could you help me fix this WiFi issue, again? I'd appreciate it very much.

EDIT: Adding the text files of the instructions from beginning to end, so that you don't have to scroll back in this thread to see what I did. Hope this helps!

Thanks! This worked!
Will this work on Linux distributions other than Ubuntu?

I haven't any current experience with other distros, however, there is no reason why it shouldn't that I know of. Just be sure to install the prerequisites; make, g++, etc., known in Ubuntu as a meta package build-essential; and the kernel headers, known in Ubuntu as linux-headers-generic.
