Does my direct tv use WI-FI data to update, unprompted, when connected with internet, when shut off
I recently noticed a spike in WI-FI data usage and it was at a period and time no one was home, and none of our cellular devices were home. I have basically eliminated the possibility of physical use during this period, and decided something is connecting without my knowledge. I eliminated cellular phones updating during this period because they weren't in range and isolated it down to Direct TV, Netflix, HBO GO, Play Station Live or our laptops, but as far as I know all were log out of and equipment was power down. So I was wondering Does my direct TV use WI-FI data to update, unprompted, when connected to the internet, when shut off? If so is there a way see and to manage when these updates take place.
