Couldn't connect using a wired Atheros AR8161 NIC

Question

This is my first time using ubuntu. I am using verion 12.04 and I can't connect through wired connection.

The network card I am using is Atheros Communications Inc. AR8161 Gigabit Ethernet (rev 08).

The logical name of this network is eth2. Is there a wrong configuration in my system?

I am using a home router, which is dynamic connection (the router has DHCP server running).

My ifconfig is:

eth1      Link encap:Ethernet  HWaddr c0:18:85:d2:c9:a3  
          inet addr:192.168.1.110  Bcast:192.168.1.255  Mask:255.255.255.0

I tried to disable my IPV6 also the problem is still not solved.

I just plugin cable to my laptop. The system say that it is connecting. Then after a while it stop trying to connect to the network — Jerrold, May 09 '13 at 08:25
Please edit your post to include the output of ifconfig. Does your system also have a wireless adapter? Problem similar to this post. — douggro, May 09 '13 at 12:01

The AR8161 cards seem to have driver support issues under most flavors of UNIX which result in the card showing up in ifconfig but not properly functioning. (Google searching the card name will yield a lot of "not functioning" post results.) Answers in this post and this post detail how to install the kernel support needed for the Atheros card.
