The range of WiFi is not much. Maybe a couple of hundred feet. So that is easy to determine whether neighbors are connecting.
On my DSL modem/router, I can log in and determine what is connected. There was ONLY one WiFi connection, and that was the DirecTV Genie receiver. It was downloading 24/7, who knows what.
I guess Genie has subscribed to various XXX movie channels.
If you find something useful, please share.
There is always confusion with the Dish/Directv resellers to say nothing of VAR's such as Montana Satellite.
