Did you try running "dhclient" in a terminal?
Did you ping your router if you are connected to one?
If so, forget the question.
>From the above I can tell you pinged a site(s) online.
Compare the response times to your router response time
if you have one.  Else, forget the suggestion.
Is Network Manager  set to automatically connect?
The URL being non-functional suggests no DN Server, thus
the question about running "dhclient".
After your response to this, we can go further to find
the trouble.
(Keep in mind that for some reason 'ping' will work when
all else fails, even sometimes when a firewall is set to block
all connections to the internet. This is the way it was
designed to work.  When I was still working for a telecommunitions
company they once set the intranet so we could not get certain
connections.  I 'pinged' the URL and got the IP address and used
it in Internet Explorer to go to that site anyway.  They
eventually blocked the IPs as well.  Google was one.)
