I just downloaded a large file and carefully watched status meter and made sure there was no other activity on my internet. I started off with 40.1GB of Data, Downloaded 21.8Gb and now HT1100 System Control Center says I have 15.3 Left. I have noticed this in the past with large files. What gives? I am not a new customer trying to get out of a contract. I have been with Hughes for a long time.
Upload also counts on Gen4 so depending what exactly you were downloading there could have been significant uploading also going on. May also have things downloading/uploading in the background that you aren't aware of.
Torrent downloading often shares part of what you have downloaded to others by uploading it back to them.
This was a direct download from steam. No data upload. I am not a nube to data usage and my system firewall is monitored carefully. The Hughes Status meter is not providing correct info on large downloads.
