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.

about getsebool and setsebool

The setsebool is used to set SELinux boolean value i.e. various configurations can be enabled or disabled using this tool. In other words, the setsebool command switches on and off the protection of SELinux. Type getsebool -a to see all such options which can be enabled or disabled at run time: e.g. # getsebool -a The following should give you a complete listing of all the vsftpd switches: e.g.  # getsebool -a | grep ftp  For example, if httpd_disable_trans set to 1, it will disable SELinux protection for  Apache web server. To disable it, enter:  # setsebool -P httpd_can_network_connect=1 To enable it, enter:    # setsebool -P httpd_can_network_connect=0
