CentOS 6.4 is installed on the physical machine, and the NIC Driver of the Atheros AR8161/AR8162 is faulty. centosar8162
This is a terrible problem, so I will write this article only for later users.
CentOS 6.4 is installed on the physical machine and Win7 to form a dual system, but CentOS has been unable to connect to the network, a closer look to find that the network cable interface is not bright. The NIC driver does not exist! Eth0 is not displayed when you execute the ifconfig command!
In Windows, it is extremely convenient for the driver genie to solve the driver problem. However, in Linux, the driver will find it by himself.
Now I have found out. For the CentOS 6.X series, if your network card is set to the Atheros AR8161/AR8162 series, download the attachment below this blog post (look carefully, the word is relatively small, can't find a message for me), put it in CentOS, decompress it, enter the directory, make it directly, and then enter the src subdirectory, and then execute insmod alx. ko command. Check that your network cable interface is shining. Run the ifconfig command to view eth0!
Go to the next pppoe dialing software.
