Having the same issues with Hughes, 2 months ago I paid extra for upgrade form 10GB to 20GB and still ran out of data 14 days before my month is up, where does all this data get used? I will stop recording to many programs or watching utube videos if that's what is using up my data. They are very poor at showing customers what is eating up the data. It would cost me $100's to cancel and move back to cable tv and don't kown how to resolve issues with Hughes and Direct TV.
If you type "Data" in the search bar I'm sure you could find tons of topics about where your data is going.
Here's one right from the top of the Tech Support area: https://community.hughesnet.com/t5/Tech-Support/Understanding-data-usage-data-loss-and-connection-pa...
