I, too, am seeing a recent improvement in speeds. It may just be coincidence, but hopefully everyone who's been affected starts seeing the same thing soon.
I can idendity what you are going through.
Below is a recommendation I provided to another Hughesnet user having similar problems:
"I have found the best way to get positive and informed attention/action is through this forum. You may have already done this, but if not, I suggest that you open a new message string specific to your situation. I know it will be a pain, but give plenty detail (e.g., what system you are using, modem, data plan, computer type, wired or hard wired connection, speed test results, how long you have been trapped with poor performance, AND any Case Numbers you have). Fortunatly, GabeU an Associate Professor on this forum seems to monitor what is going on and he should see your post. He is very thoughtful and has provided me with valuable advice. He is also able to ping forum moderators and get their attention. Hughesnet people like Amanda and Liz also monitor this forum, they are sharp and have always been helpful with my technical issues."
