I am using a Sony VAIO Vista OS.
Recently, I encountered this problem :
1. Wireless adapter is enabled but no wireless internet connection.
2. The wireless light IS NOT 'ON'
3. Despite ENABLED the wireless adapter, it still does not connect
4. After I restart, there is internet connection but only lasted few minutes before it is OFF and wireless adapter becomes DISABLED and the light is OFF
How can I resolve this issue ?
