Default Smart mode Wi-Fi reset?

is it possible to reset the database used for the "Smart mode" Wi-Fi option? When I first got my device I remember after a day or so the Wi-Fi would automatically turn on if I was in the vicinity of my home and my parent's home. Now it won't turn on in either locations, however it will turn on in certain locations "randomly" that do have Wi-Fi... for example today at work it would turn on several times after turning it off and entering certain floors that carried Wi-Fi. There has to be a database of some sort or a way to reset it so the only two locations that matter to me, home and parent's home, get preference to "Smart mode". any suggestions?
