Your video is buffering likely because of congestion (the number of people using HughesNet simultaneously in your area).
When this buffering happens to you, go to your modem's status page at http://192.168.0.1/#!/home/status and check what the number is next to State Code, then post that number here.
I have a white circle spinning in the middle of the screen with video frozen?
If the modem is fully operational and green across the board (no red checkmarks), then the problem is likely congestion and internet latency issues, including how sites handle requests. When latency is high, sites think they've lost connection to you and try to resend the request, and this messes things up.
You can try rebooting the modem (may not solve the problem when there's a lot of congestion, but it's worth a try), or modify your viewing habits. Keep in mind that satellite internet can't work like cable, DSL, or fiber. While you can stream with it, you have to adjust your habits, behaviours, and expectations.
I've re-booted several times with no luck I had, Dishnet never had a problem with youtube videos beginning to think I down graded instead of upgrading. I haven't been able to watch one single youtube.
OK, but if something isn't working for you at all, you'd spend less money paying the ETF than continuing with the contract. However, it's your decision, of course.
