Help, I've tried the other fixes used for ubuntu 15.10 and the Qualcomm adapter but nothing is working for my lenovo ideapad 500 with the Qualcomm Atheros QCA9377 wireless adapter running 14.04.3. could i be using the wrong terminal commands? im using this set of commands found in another post:

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 http://filebin.ca/2LVgpjSgiT56/backp...-11-05.tar.bz2
unzip backp...-11-05.tar.bz2
cd backports-ath10k-2015-11-05
make defconfig-ath10k
make
sudo make install
git clone https://github.com/kvalo/ath10k-firmware.git
sudo cp -r ath10k-firmware/ath10k/ /lib/firmware/
sudo cp -r ath10k-firmware/QCA9377 /lib/firmware/ath10k/
cp firmware-5.bin_WLAN.TF.1.0-00267-1 firmware-5.bin
Reboot

any help appreciated

Please try:

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 tell us if it's working.

  • It worked! You are awesome, Thank you for the help! So happy to have my wireless back! – ubunjz Nov 27 '15 at 3:24

This is how I fixed the WiFi issue in my Laptop

Identify your WiFi device. Open a terminal and issue:

lspci  | grep Network
# It should display the name of your WiFi card
# If the output is similar to the one below, you are in luck, we can fix this easily
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.

# Modify the config files
echo "options ath10k_core skip_otp=y" | sudo tee /etc/modprobe.d/ath10k_core.conf

# Download the backport
wget https://www.kernel.org/pub/linux/kernel/projects/backports/2015/11/20/backports-20151120.tar.gz

# Extract it
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

# Download the firmware for the WiFi card
git clone https://github.com/kvalo/ath10k-firmware.git

# Copy the firmware to appropriate locations. 
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.

It happened on my Asus Laptop and I've Tried something like this,

rfkill list all

Then it will show something like this:

0: hci0: Bluetooth
Soft blocked: no
Hard blocked: no
1: phy0: Wireless LAN
Soft blocked: no
Hard blocked: no
2: acer-wireless: Wireless LAN
Soft blocked: yes
Hard blocked: no

See the acer-wireless: Wireless LAN has a Soft blocked?Then do this,

sudo modprobe -r acer-wmi

Check if there's blocked wifi like example above, and Check your Setting on Wifi, if it's change to "Enabled" after you do the last sudo above on terminal.
