I'm in really a big trouble here i have Windows Vista installed on my PC but from few days i have a random drop of internet access. I can successfully ping sites from command prompt for example techarena.in but i can't access with my any of the browsers and every time i have to restart my computer to get internet access back. And after few minutes i again face same problem. Please let me know if someone have same kind of problem or someone have solution for this. Thanks in advance.
