Qualcomm Atheros AR8161/8165 PCI-E Gigabit Ethernet Controller

What is the output of:

sudo lshw -C network; lsb_release -a; uname -a

Thanks

Thank you very much
but
tell me how
I can know the output of your code if
 I can't connect to internet...
Remember ... I'm looking for the driver of my ethernet card

Do you have access to another computer with network connectivity? Go to:
http://askubuntu.com/questions/165192/how-do-i-install-drivers-for-the-atheros-ar8161-ethernet-controller

The first two commands:
sudo apt-get install build-essential linux-headers-generic linux-headers-`uname -r`
wget -O- http://linuxwireless.org/download/compat-wireless-2.6/compat-wireless-2012-07-03-pc.tar.bz2 | tar -xj

Copy the drivers down to your home directory and put it in a directory called "compat-wireless-2012-07-03-pc" Copy that entire directory to a memory stick, and then load it onto your computer. Then execute the last four instructions:
cd compat-wireless-2012-07-03-pc
./scripts/driver-select alx
make
sudo make install

Then you can either reboot, or issue this command to reload the kernel:
sudo modprobe alx

Hope that helps. I have that directory saved on my machine so every time there's a kernel update I can get my network connectivity back.

Ok thanks

but after instruction ma.e
error 126

excuse me
instruction make
