So recently i downloaded Tasker thinking i could turn WiFi on automatically when i'm at home and off when i'm not. Anybody know exactly how I can do this? Honestly i am really confused.
Yes, it can be done. I have used Tasker mainly for this feature. There's a page at YAWA - Wifi Automate when near cell tower and AP - Tasker Wiki that describes what to do. It's based off the cell tower that your phone is connecting to, so there's no need to enable GPS.
