Well If you feel more confortable with centos go ahead, if you want to 
learn how to fix this problem we requiere more information, sometimes 
different kernels detect the NICs in different order, for example I use 
dual boot for some training and ubuntu detects the nics in the correct 
order, fist integrated (eth0) and then pci cards (eth1 and so on), and 
when I boot with centos they are changed, eth0 pci and eth1 integrated, 
that is easy to fix with real information..

the information required:

1- Are your NIC detected? provide lspci output:

$ lspci | grep Ethernet

2- Is your system aware about the interfaces ? NOTE: ifconfig by default 
only show interfaces with UP atribute)

$ ifconfig -a

Probably at this step the interfaces are recognized but with different 
name, that is because ifconfig eth0 wont show the information...

3 - Show the content of /etc/udev/rules.d/70-persistent-net.rules file.

This file is used for udev to map a network interface by its MAC 
address, this way you can get persistent names for your hardware, most 
of times the easy fix is change the name in this file to the interfazce 
name you want and reboot.

Hope this helps.
