Setup: I have a Nexus 7 mounted in my car that I use for navigation and entertainment. I have a Razr Maxx that I hotspot to feed the N7. On the Maxx, I have an app to fire up the hotspot and to shut the hotspot down. What I am looking for is a way to shut off hotspot and turn on wifi back on with one button push. Thanks. PS: I have Tasker if that helps.
