If you can't ping your gateway, it's either a network problem,
or a firewall problem.

Try pinging the gateway, and then dumping your arp table
('arp -an'). If you see the mac address for the gateway in
your arp table, it's probably a firewall issue. If the
mac address isn't there, it's a network problem
