I have a Samsung Galaxy S III and I have a problem which occurs on all the roms I have tried so far: Paranoid Android, Cyanogenmod and Ultimarom: When using Automateit to frequently turn wifi on and off, wifi breaks after a while (no fixed time, sometimes there are days without problems), which means wifi can not be turned on again, neither manually, nor automatically. When turning it on, no networks are shown. The only fix is a reboot.
Now I am looking for a solution which could avoid the reboot. I want to now if there are shell commands to restart/reload the wifi module manually. Then I could use the Automateit-Shell extension to frequently do this automatically. Does anyone know how to do this?
