Network automatic shutdown

I am using Vista Home Premium on HP Pavilion laptop. I connect to internet

started with the networking.
Suddenly, the page can not be loaded in the browser. When I run diagnostics
from browser (IE7), it says that 'not able to connect with the proxy server.

Please suggest a way-out.
