Plug in the network cable, the network cable light is not bright, because the NIC is bad, to pay to buy a separate network card, but do not want to spend money to
provides the ability to analyze the partition information in the startup parameters.Flash hardware driver: Provide flash read/write/erase and other functions. Because the Atheros partition information is obtained in the kernel startup parameters, there is also the function of analyzing the partition information of the starting parameter, and the MTD device is ad

Think about it as if the driver is not installed properly.I found and TP-link TL-WN721N, TL-WN722N, fast fw150u, are using the chip of atheros ar9271.Root @ Ubuntu :~ # Uname-Linux Ubuntu 2.6.32-33-generic # 70-ubuntu SMP Thu Jul 7 21:0
Solution to NIC Driver problems of Atheros AR8161/AR8162 in CentOS 6.4
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
I do the network card driver, the main content is to design and improve the rate adjustment algorithm, With the new standard of 802.11 protocol cluster more and more, the rate is more and more high, modulation coding method is also more and more, generally speaking, the higher the rate is more likely to drop packets, the lower the rate is more stable, this is the overall situation, but not necessarily the law, so, only with a fixed rate to send is obv
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 Windo
