Depois de muita pesquisa, descobri este link. link com as seguintes informações.
This fixed it for me: I turned off the Dell Quickset. Go to - Location Profiler - Profile Switching - and set it to manual.
With Dell Quickset - Location Profiler - turned on (set to automatic), I had the problem of: I had to keep checking IE 8's "automatically detect settings" box every time I come out of sleep mode, hybernate mode, or reboot. Web pages would not display, until I check the "automatically detect settings" box again, every time.
Espero que isso tenha ajudado.
-Boa sorte.
