I have a Dell laptop with Ubuntu 12.04 LTS (kernel 3.5.0-49-generic) with qualcomm atheros qca9565

The first time, I did update and all the connections with the internet were lost.

Step by step, I restored the wired connection and then the wireless one. Yesterday I got a message to update due to an error, so after the second update, I lost the wireless connection : there is no wlan0 anymore, only eth0 and lo.

Ii can see all the parts of atheros card but I can't get to install it. I downloaded drivers and I tried to install them but without success.

I have read almost anything here and elsewhere about how to retrieve this and that but nothing worked.

I am new to Ubuntu. I need to restore my wireless connectivity. If possible, write me detailed instructions.

Let's install the backported driver and see if that fixes your wifi connection but first remove any drivers you installed yourself.

Go here backport driver and download the newest driver to your computer then place the file on your desktop and right click and extract here.

Then do:

cd ~/Desktop/backports-3.15-rc1-1
make defconfig-ath9k
make
sudo make install
sudo modprobe -rv ath9k 
sudo modprobe -v ath9k

When there is an update to the kernel you will have to do the following.

cd ~/Desktop/backports-3.15-rc1-1
make clean
make defconfig-ath9k
make
sudo make install
sudo modprobe -rv ath9k 
sudo modprobe -v ath9k
