Be abused by this problem, only for the later not to be abused, so write this article.
CentOS 6.4 installed on the physical machine and Win7 to form a dual system, but CentOS has been unable to network, a careful look only to find that the network cable interface is not lit at all. Because the NIC driver does not exist! Your execution of the ifconfig command also shows no eth0!
The next Driver wizard in Windows is extremely handy for driving problems, but you'll find them on Linux.
Now I have found, for the CentOS 6.X series, if your network card is Atheros ar8161/ar8162 series, then download the attachment below this blog (look for, the word is small, can not find a message to me), put in the CentOS, unzip it, into the directory, Directly make, after the matter, then into the SRC subdirectory, and then execute the insmod alx.ko command. Look, your cable interface has been flashing. Execute the ifconfig command to see Eth0!
Then go to the next PPPoE dialing software, dial the bar teenager.
