A few other things which might be relevant:

Have you tried to disable the firewall and restart the network:

[as root]

service iptables stop

service network stop

service NetworkManager restart

..if that doesn't help then post the output from

[as root]

route -n

ethtool eth0

ifconfig eth0

ping 127.0.0.1

chkconfig --list | grep [35]:on

..which may shed some light on what's going on.
