Didn't work for me. All it does is turn your wifi off and back on to reset it. Well guess what  I wouldn't be using a touch screen phone if I didn't have fingers for crying out loud ! Problem for reference: Galaxy S3 recently started losing connection if I moved more than 5-10 feet away from my router even with a very strong signal. After installing this app I can see it rapidly cycles from connected to disconnected  then app turns wifi off  then back on  scans  connects then disconnects all in a constant loop.
