"Bingo! That works…now all I have to do is remember every time I come home to turn on airplane mode and every time I leave home to turn off airplane mode (at least a 1000 times a year). Is there any way to automate this to somehow prefer my home network or write a script that when on my home network would turn on airplane mode?"
