How is the data usage not accurate? How is there lack of help from Hughesnet? A little more info would certainly be helpful.
In which way is your data usage not accurate ?
Which of the three available usage meters and two usage history displays are you using ?
What service plan are you on ?
What operating system(s) do you use ?
Are you connected directly to the modem or do you have a router ?
For your individual issue, I would suggest starting your own thread, and describe in as much detail as you can what is going on, like if it happens at specific times, after doing certain things, how long it takes to go back to normal. That kind of thing. There are long time users on here who may be able to help, and the official reps are at the corporate level, so they have a lot of knowledge, as well.
