Whenever the user tries to connect to the WiFi,A message appears "WiFi is disabled by the hardware switch".When the user navigate to the wireless setting,then one finds that the aeroplane mode is on ,and switching it off does not help as it gets switched on by itself .The WiFi driver which my laptop has is "RT3290 Wireless 802.11n 1T/1R PCIe "
