Are your proxy settings correct? Check it from
System Settings>Network>Network proxy

Ok, are your network settings correct?...I mean IP settings?. Try pinging www.google.com– SrijanJul 28, 2012 at 7:55

Beyond pinging other servers, you can get information on your IP settings by choosing "Connection info..." from the network panel menu or by entering
ifconfig
into a terminal window. Jul 28, 2012 at 9:04
if it is a dsl connection with username and password , you will have to set in "edit connection" in the network manager drop down menu. previously you may have connected through windows and then installed ubuntu, so it was working, now you will have to set it separately for ubuntu.
Turn off the firewall and see if that fixes it. "sudo ufw disable" if it does then configure it correctly (google it) don't just leave it disabled!
