Can you do the following things and provide screenshots:
dmesg | grep eth
cat /etc/sysconfig/network-scripts/ifcfg-eth0
cat /etc/sysconfig/network-scripts/ifcfg-eth1
cat /etc/sysconfig/network-scripts/ifcfg-eth2
Make sure that the MAC addresses in these configs matches the network cards you can see under "edit settings" (maybe provide screenshots of those as well).
