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 inet6 addr: fe80::c218:85ff:fed2:c9a3/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:17133 errors:17 dropped:0 overruns:0 frame:247488 TX packets:10304 errors:7 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:22986154 (22.9 MB) TX bytes:1059388 (1.0 MB) Interrupt:17

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 9 '13 at 8:25
    
Is your connection statc or dynamic? –  tuxtu May 9 '13 at 9:08
    
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 9 '13 at 12:01

1 Answer 1

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.
