you need to mannually edit the MAC address of your new NIC card

nano /etc/sysconfig/network-scripts/ifcfg-eth0

With CentOS 6 everthing is handled by udev now. Go into /etc/udev/rules.d and delete the 70-persistent-net.rules file and reboot. If you open it berfore hand you will most likey see the original NIC MAC listed as eth0 and the new one as eth1.

 

Now you need to edit /etc/sysconfig/network-scripts/ifcfg-eth0 and manually update to the MAC of your new NIC card.

 

If network adaptor icon not show

#service NetworkManager start
