How to enable/disable Wifi in Toshiba Mini Notebook

For Toshiba Mini Notebook series (NB 200 and NB 300 series), there is no hardware switch for turn on or turn off the wifi. Basically you can enable or disable by pressing and hold Fn button with F8 button (look the WIFI symbol behind the F8 text). You will see on the screen the icon menu of the WIFI and Bluetooth. Just press and release the F8 button but keep press the Fn button to select the icon.
