Solution to installation of CentOS Wired connection failure in AR8161

Solution to installation of CentOS Wired connection failure in AR8161

If your computer is installed with CentOS and you cannot use any lines of Special Products in Nanjing to access the Internet, run the following command:

lspci| grep -ieth

Result displayed on my terminal: 02: 00.0 Ethernet controller: Qualcomm Atheros AR8161 Gigabit Ethernet (rev 08)

Run the following command:

ifconfg

The connection displayed on the terminal does not contain eth0 or ethx (x represents 1 ~......) ,

If your computer terminal displays a similar appeal, you don't have to worry about it. This is because the NIC driver is not installed. Well, let me share my solution:

Note: The NIC of my computer is Atheros AR8161. Maybe your computer is not. Please download the driver related to you, but the installation methods are similar!

I am here to install the Atheros AR8161

Tools/Raw Materials

Required tools: Nic drivers related to your computer

Method/step

1. Download The Atheros AR8161 driver. The URL below is

Http://pan.baidu.com/s/1gd3hNvd

After the download, extract, decompress the Directory: alx-linux-v2.0.0.6

2. gcc is not installed in CentOS by default. You can execute gcc

If the terminal displays:

bash :gcc:commannotfound

So it indicates that your computer has not installed gcc. At this time, execute the following command to install gcc

Run the following command:

yum install gcc

Wait until the gcc installation is complete.

3. Install kernel-headers and kernel-devel:

Run the following command on the terminal:

yum install kernel-headers-$( uname -r)kernel-devel-$( uname -r)-y

4. Switch the path to the unzipped file under the terminal, that is, switch the path to the folder alx-linux-v2.0.0.6.

Run cd./src/

Run the following command:

make In this case, an alx. ko file is generated in the src folder.

Run the following command:

mkdir /lib/modules/2 .6.32-358.6.2.el6.x86_64 /kernel/net/wired

You do not need to press the "complete" button. You only need to find your own kernel directory. This step only creates a wired directory. Therefore, you can use the "TAB" key to complete the configuration, it is important to find your own directory.

5. Copy alx. ko to the folder created in the previous step.

Run the following command:

vi /lib/modules/2 .6.32-358.6.2.el6.x86_64 /modules .networking

You don't have to press the "complete" button. You only need to find your own kernel directory. It is very important to find your own directory.

Add alx. ko to the first line of modules. networking.

6. Run the following command:

vi /etc/sysconfig/modules/alx .modules

Add the following content to alx. modules:

#!/bin/sh if [!-c /dev/input/alx .ko]; then exec /sbin/modprobe alx> /dev/null 2>&1 fi
