Perhaps the network is down. Try using that connection and then opening google in the Web Browser.

Check if you have the right IP, in network settings. Try unplugging your modem and router for atleast 30 seconds, let me know how it goes.

did not work

I'm fine was playing LBP and R2 Beta. That was 2 hours ago.

Try going to network settings and disabling "Media Server Connection". It's been known to cause problems.
