From quite some days i am facing this problem. I connect to the internet, everything is working fine when suddenly i lose my internet connection ( The tray icon still shows it's connected and so does the network ) and i am logged off from everywhere. I tried formatting the pc, still the same. And after this happens, if i try to disconnect my connection by clicking on disable or if i try to open the Control Panel or Network and Sharing Centre, it goes Not responding. What could be the problem ?
Drivers are updated, i format the pc and reinstalled the OS, i have a laptop which i bought an year and some months back. No i didn't try a different network card and if it's a hardware problem, why does it connect back on restart rather than just not connecting due to faulty hardware ?
