Hi Cameron, I tried @YoGem's suggestion, didn't work though. It doesn't seem to have anything to do with sleeping functions, since it happens when the phone is "awake", i.e. screen is on. It simply disconnects the wifi after a few minutes away from the router. Some months back, this worked well because it automatically turned the wifi on again when I was within range, which helped me save battery power. Now, it only turns off the wifi though, never back on again. Not a major issue, just annoying that I have to remember to manually disconnect mobile data every time I come home, and when I repeatedly forget, I run out of data.
