How To Fix No Wireless Network In Ubuntu 14.04 ,14.10 and 16.04

Today I am going sharing how fix wifi issue after formate your system or reset in Ubuntu.Mostly when your install some feature are not working like Wifi , Touchpad etc. Here I am sharing Wifi related solution.Ubuntu did not detect any Wireless network. you can only use LAN connection.

This is common issue in Broadcom network adapters in Ubuntu.

Step 1:- 

• Get the image of ubuntu. Copy it to external device like USB or DVD.Just Copy it , don't burn it as bootable  USB.
• Now boot into ubuntu and copy this ISO Image File to your home Directory.

   

 Step 2:- 

• Open Terminal (Ctr+Alt+T) and Run Following Command.
• sudo mkdir /media/cdrom
• cd ~
• sudo mount -o loop ubuntu-* /media/cdrom
• Actually We Just manually mounted the IOS image as if it was a CD

Step 3:-

• Go to Unity dash and Search "Software and Update"

 

•  Kindly make sure In First tab in Ubuntu Software , check the option of CD Rom With Ubuntu..

• It will ask for your password and reload the software source.Next is to go in Additional Drivers tab and select the propriety and click on Apply changes.

 

• Once the drivers have been installed,you will see that Ubuntu now recognizes the wireless networks in range.

-------------------------------------Second Way ------------------------------------

If run above step still it not working then you can use second option.You just Open Terminal (Ctl+Alt+T) Run Bellow Command .

• 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/kernel/projects/backports/stable/v4.4.2/backports-4.4.2-1.tar.gz
• tar -zxvf backports-4.4.2-1.tar.gz
• cd backport-4.4.2-1
• make defconfig-wifi
• make
• cd backport-4.4.2-1sudo 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

And it should work after a reboot.It will fail when a new kernel is installed through updates until the kernel is patched to support the wifi. When that happens you will need to:

• cd backports-4.4.2-1
• make clean
• make defconfig-wifi
• make
• sudo make install 

Restart your system and check.

 Now check your Wifi working Fine. I hope this post helped you to fix no wireless network issue in Ubuntu 14.04,16.04. If you have questions or suggestions, feel free to drop a comment.
