Installing Qualcomm Atheros AR8162 Fast Ethernet Driver on Lenovo G400

I was preparing Lenovo G400 laptop for my linux class, after I installed CentOS 6.5 on it, tada,,,, my ethernet adapter won't show up. I checked with ifconfig command but where the hell my eth0 ??. Then i type the command below :

# lspci -v

01:00.0 Ethernet controller: Qualcomm Atheros AR8162 Fast Ethernet (rev 10)
    Subsystem: Lenovo Device 3802
    Flags: bus master, fast devsel, latency 0, IRQ 32
    Memory at 90500000 (64-bit, non-prefetchable) [size=256K]
    I/O ports at 2000 [size=128]
    Capabilities: <access denied>
    Kernel driver in use: alx

It seem my wired network adapter do not have its driver. After searching on the net then I find this great article. I wrote it out on my blog to make it sure I have notes for the trouble.

This is how we troubleshoot it :
 
First download this file :
alx-linux-v2.0.0.6.rar

unrar it, run make command, change directory to src then run insmod alx.ko.
