Try the following


$ ping -c 5 google.com
$ ping -c 5
see if you get a response
2) now try and initiate a connection manually

$ telnet google.com 80

For troubleshooting,
* Trying Disabling Iptables and see if that solves the problem
$ /etc/rc.d/iptables stop
also check if your routing table is configured correctly
$ route -n

And lastly, see if the network interface has been correctly assigned
IP address, netmark and gateway
$ ifconfig -a

Hope this helps
