I want to use eth0 driver, but my network card is UNCLAIMED.

I use Killer e2200 Gigabit Ethernet controller.

Please tell me how to install the Networkdriver and how to use eth0.

If you have installed OS and you want to run Network Card as new hardware, you must ask the vendor for network drivers. Usually network drivers come with source pakage of kernel modules.
You must compile driver module for you kernel.

1. 
   

   install "build essential" utilites

   
   
   

   $ sudo apt-get install build-essential
   

   
   



2. unpack your source pakage to some folder



3. go to this folder


4. 
   

   do this:

   
   
   

   $ ./configure
   $ make
   $ sudo make install
   

   
   

After installation you can load just compiled module by enter command:

$ sudo insmod your_module.so
$ ifconfig eth0 up

The latest network devices usually take a while to work their way into the Linux kernel. All drivers are usually built into big distributions like Debian (or Ubuntu) and Centos.

The other answer answers here give great detail on how to compile the driver module and insert it - if you look at the Linux source code, you can "grep" your device name in the /drivers/net directory eg.

grep -ri e2200 /usr/src/linux*/drivers/net/

Or

grep -ri killer /usr/src/linux*/drivers/net/

It might yield something like:

I've trimmed some lines for brevity. But the module names are the same as the directory before Kconfig, so you can check if it is active with lsmod:

lsmod 

Sometimes my intel drivers for my onboard Wi-Fi dies, then I have to remove and re-add it:

rmmod iwlmvm
modprobe iwlmvm

Then magically it works again. I still need to contribute this fix to the NetworkManager project...

If this returns "alx", then the driver is already loaded:

lsmod | grep alx

If not, you're out of luck. You can manage the interface with the "ifconfig" or "ip link" commands:

ifconfig
ip link 

Newer Linuxes don't use "eth" as interface names any more.

So I grepped my kernel tree for "killer" and "e2200" and couldn't find anything. Then I did a web search, and found out that is is an Atheros device, and similar to the "alx" driver. Someone updated the driver to work with your card, lucky you. If there are enough cards like that out in the world, or he upstreamed it, all you have to do is to update Linux and it will just work.

If not, you will have to compile it yourself, as per How do I get a Qualcomm Atheros Killer E2200 gigabit ethernet card working? from https://ubuntuforums.org/showthread.php?t=2008332&page=7&p=12604916#post12604916.

Welcome to Linux! No go out and buy some older hardware that someone has already made free drivers for... :-)

Please run the command:

lspci -nn | grep 0200

Is your device 1969:e091? Here are instructions to get your device working. First, I assume you are running Ubuntu 13.04:

lsb_release -d

If not, stop as these instructions are written for 13.04 only and will have unknown results on earlier Ubuntu versions. These instructions have been tested and are working in 13.10. Get a working wireless connection, open a terminal and do:

sudo apt-get install linux-headers-generic build-essential

Now download this to your desktop: https://www.kernel.org/pub/linux/kernel/projects/backports/stable/v3.10/backports-3.10-2.tar.bz2 Right-click it and select 'Extract Here.' Now back to the terminal:

cd Desktop/backports-3.10-2
make defconfig-alx
make
sudo make install
sudo modprobe alx

Your ethernet should now be working.
