@rem save the script wherever you'd like to
@rem create a shortcut named "wifi" and put it in a place that's in your path (shortcuts folder, system32, whatever..)
@rem set the shortcut to run as administrator! IMPORTANT!
@rem run "wifi on" or "wifi off" and enjoy your life.

@rem the default wifi interface name is "Wireless Network Connection" just cause that's the way it's on my computer.
@rem you can run "wifi-set-on-off.bat" script without any parameters to see what's your wifi interface name (I've added "Wi" filter assuming it will be WiFi or wireles..)

@ECHO OFF
