Eh, count your blessings, I was on DIAL UP until I got HughesNet. Lately ive been in rough shape for speeds, dont know whats wrong
But before that, it was amazing. I was able to download stuff even on throttle near 1mbps, and watch fairly high quality video
Even with these horrifically slow speeds, its better than dial up. If youre on Hughes youre probably a rural person, and its the best we'll get except for if Elon Musk really gets that SpaceX stuff going
Anyway my advice, just watch stuff at lower quality. 480p is standard television quality, and I can stream that on Youtube right now without problem. In fact, I sign into my buddy's Amazon Prime to watch movies, and I can watch on their good quality with a little bit of buffering(like 10 second every 5 minutes) and my download speed is currently 26k on Steam for a game download.
Ive also never seen a website failed to connect message. Im thinking you should probably reboot your modem, and call techsupport again. Could be your dish or modem is messed up bad and needs to both be replaced or reaimed
