Possible DNS problems also can prevent it..

Re: If PING doesnt works

DNS is the system that translates the address www.google.com into an IP-address. So when this not works the ping commands does not know to which IP it should ping.
For more information about DNS see
https://en.wikipedia.org/wiki/Domain_Name_System

Do try the ping command from the same machine from which you are going to the internet? (Then DNS works, otherwise you could not surf.

Yes, probably it is a firewall problem.

Have you the IP-address of a router or another computer in your network that you can ping? So you can test if the ping works in your local network.
