I have installed Windows 8 pro in my Lenovo G 500 laptop yesterday. I have installed all the drivers which are provided along with my laptop. After I installed the WiFi driver my WiFi worked and once I have restarted the computer the WiFi connection is lost and it displays as WiFi(off). I have tried uninstalling all the drivers and installing them again. Please tell me the solution with a full description as I am new to Windows 8. Thanks in advance.
