Like Gary, I am just to far back in the woods, also using wireless encryption.
In my case it is best described as "unauthorized use by an authorized device"
You simply can't trust those tablets, phablets & e-readers to stay within the "rules".
That sneaky Nook HD+ of mine once woke up from a "slumber" and downloaded a completely new OS in the middle of the night.
It has to be hard off or airplane mode.
all 20 gb of my monthly data disappeared in ONE day! that is not possible. how do i fix it have been on hold now for 30 minutes.
Yes, it is possible. Depending on your speed, something steadily using your data could burn through 20GB in as little as an hour.
This thread is very old, so if you would like some help to figure out what is using your data so quickly please start a new topic, which you can do by clicking the blue "Start a topic" button on the upper right while within the Tech Support section.
With this said, if you have a DirecTV receiver connected to HughesNet it wouldn't surprise me if this is where the problem lies.
While 20 gigs seems 'impossible' to go through in a single day, depending on your activities, it actually is very possible to use this much data in a single day.
For example, many of the Xbox One S digital games require downloading from Microsoft..and many of these games are HUGE.
Call of Duty WWII, by itself, is some 54.95 GB...even Trivial Pursuit is a whopping 821.48 MB.
If your streaming several movies and/or watching hours of OnDemand video, this will also add up to a huge amount of data.
A Windows 10 Update will run you anywhere from 1-2Gigs.
While these are obviously just examples that I've listed above, do you think that it is possible that you downloaded content today not fully realizing the sizes of those downloads?
