Can't access internet.

I have NIS 2010 and a Sony VGN-NR120e.

 

I am not able to connect to any of my browsers except Firefox. I get the same "IE cannot display webpage" each time. I tried going into settings and turning off smart firewall, but that didn't work. I've tried shutting off NIS as a whole, but it didn't work. I have been trying for a couple weeks and I have no idea what to do next.
