Hi, I installed CentOS 6.4 and am not able to reach it or ping out from the box.  I started the network and ifconfig -a shows 3 devices, localhost,  p4p2, and wlan0 . The HWaddr is different for p4p2, and wlan0.  As far as I know I only have one NIC card.  Looking in dmesg is how I discovered eth0 was renamed to p4p2. This is a year old unmodified i3 Dell, except for the second HD I added. Any help much appreciated. Keith
