the interface is probably configured for DHCP via /etc/sysconfig/network-scripts/ifcfg-eth0 and your system is undoubtedly running network-manager.
I don't know *how* to tell if I'm running network-manager, but, I'm running whatever everyone else runs on Centos since the home broadband network has been working for a year or more with this laptop without problems.
When I set the laptop back to normal (on the home wireless network), here is what shows up when I right click on the network icon: http://i43.tinypic.com/11h7ynk.png
Interestingly, that ifcfg-eth0 file doesn't exist in: $ ls /etc/sysconfig/network-scripts/ifcfg-eth0 => ifcfg-Auto_eth0 ifdown-post ifup-ippp ifup-tunnel => ifcfg-lo ifdown-ppp ifup-ipv6 ifup-wireless => ifcfg-wlan0 ifdown-routes ifup-isdn init.ipv6-global => ifdown ifdown-sit ifup-plip net.hotplug => ifdown-bnep ifdown-tunnel ifup-plusb network-functions => ifdown-eth ifup ifup-post network-functions-ipv6 => ifdown-ippp ifup-aliases ifup-ppp => ifdown-ipv6 ifup-bnep ifup-routes => ifdown-isdn ifup-eth ifup-sit
But, that file does apparently exist elsewhere: $ sudo updatedb; locate ifcfg-eth0 => /etc/sysconfig/networking/devices/ifcfg-eth0 => /etc/sysconfig/networking/profiles/default/ifcfg-eth0
$ cat /etc/sysconfig/networking/devices/ifcfg-eth0 => DEVICE="eth0" => NM_CONTROLLED="yes" => ONBOOT=yes => TYPE=Ethernet => BOOTPROTO=none => DEFROUTE=yes => IPV4_FAILURE_FATAL=no => IPV6INIT=no => NAME="System eth0" => UUID=5fb06ba0-0bb0-7ffb-45a1-d6edd65f3e03 => HWADDR=A0:BE:C1:D8:E5:F1 => IPADDR=192.168.1.254 => PREFIX=24 => GATEWAY=192.168.1.20 => LAST_CONNECT=1346858976
Q: Does the information above help?
