Don't worry. I'm glad to help.

There's two ways to turn off the hotspot: 1) change the mode from ad hoc to managed 2) turn off the wifi interface. I'm not sure about the operation of the wifi switcher, but what the wifi.sh script is doing is to

When wifi is up (no matter it is in ad hoc or managed)
1) turn off the interface
2) unload related modules
3) stop the related process
4) notify the user wifi is turned off

When wifi is down
1) turn on the interface in managed mode
2) load related modules
3) start the related process
4) notify the user wifi is turned on


Therefore, when you run the script wifi.sh I provided, you may look at the screen for notification.

Also, if you're using QBE, you might notice the change in color of the icon as wifi.sh would return different exit code for different status.

Hope this helps.
