Centos 6 - No network connectivity

Installed Centos 6 and I cannot get Centos to see my network adapter.

Here is my getinfo.sh dump: http://pastebin.centos.org/37890

lscpi can see the correct adapter. Do I need to install the driver for this adapter or enable something?

Welcome to the [i]CentOS[/i] fora and congratulations on being one of the few who has obviously done the background reading [i]before[/i] posting.

In theory, that device should operate correctly with the "one size fits all" [b]r8169[/b] driver that is present in the distribution.

How have you attempted to configure the system?

Please list the files present in your [b]/etc/sysconfig/networking/{devices,profiles}/[/b] directories.

Hie.
You do not mention whether you are using GUI or not. In any case, I have faced a similar challenged and I solved it using the ifconfig command; Simply

ifconfig eth0 up

In your case, I saw the dump, and I think CentOS is seeing your NIC but somehow its down. If you are using GUI, go to NETWORK icon, left click it, then click on SYSTEM ETH0.

I hope I understood your question correctly, post more details if I didnt get it right.

Hope it helps
