No Wifi on Acer Aspire E5 573 on any Linux Platform

Question

I dual booted my Laptop Acer Aspire E5-573 with Windows 10 and Ubuntu 15.10 and every since the first day I'm not able to use WiFi on any linux platform. I did everything I could have done still no use. No additional drivers available for me on Ubuntu but I'm perfectly able to use WiFi on Windows 10. WiFi chip in my laptop is Qualcomm Atheros QCA9377 Wireless Network Adapter. Please find me a solution for it.

Solution

It appears that you need but are missing the required firmware. With a working internet connection by ethernet, tethered or whatever means possible, open a terminal and do:

wget https://github.com/kvalo/ath10k-firmware/archive/master.zip
unzip master.zip
sudo cp -r ath10k-firmware-master/QCA9377 /lib/firmware/ath10k/
sudo mv /lib/firmware/ath10k/QCA9377/hw1.0/firmware-5.bin_WLAN.TF.1.0-00267-1 /lib/firmware/ath10k/QCA9377/hw1.0/firmware-5.bin

Reboot and your wireless should be working.

Is there a clue in the message logs? Please open a terminal and run: dmesg | grep ath10k Please edit your question to add the result.

whenever I try sudo cp -r ath10k-firmware/QCA9377 /lib/firmware/ath10k I get sudo: unable to resolve host nachiket-acer

for sudo apt-get install git this is the output:- Reading package lists... Done Building dependency tree Reading state information... Done Package git is not available, but is referred to by another package. This may mean that the package is missing, has been obsoleted, or is only available from another source E: Package 'git' has no installation candidate

[chili555]

I wonder why a commonly available package, git is not installable, along with all its dependencies, on your system. packages.ubuntu.com/wily/git That is a good subject for a new, separate question. I will therefor amend my answer to provide an alternate method to download and install the missing firmware.
