Qualcomm Atheros QCA9377 wireless not working on lenovo with Ubuntu
This is how I fixed the WiFi issue in my Laptop
Identify your WiFi device. Open a terminal and issue
lspci | grep Network
mansoor ~ $ lspci | grep Network 03:00.0 Network controller: Qualcomm Atheros Device 0042 (rev 30)
Once you have made sure that the Network device is the one above, follow the below steps to install the driver for WiFi ##### Install git and tools to compile the driver
sudo apt-get install build-essential linux-headers-$(uname -r) git Issue the following commands one by one. Anything written after “#” is a comment and you don’t have to execute it.
echo "options ath10k_core skip_otp=y" | sudo tee /etc/modprobe.d/ath10k_core.conf
wget https://www.kernel.org/pub/linux/kernel/projects/backports/2015/11/20/backports-20151120.tar.gz
tar zxvf backports-20151120.tar.gz
cd to the directory, compile and install it. The commands 'make' and 'make install' will take some time to finish
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
Reboot your machine. That’s it. Your wifi should work now until you do a kernel update.
