If the service doesn't work well for you, it makes sense to go with someone else and see if they do better.
Note that if you're still under contract, penalties apply for discontinuing early. See the subscriber agreement at https://legal.hughes.com/SubAgree-03-16-17.cfm
We are planning to discontinue our account next month with HN and try a competitor satellite internet service since others in our area can stream movies and are happy with their service.
Streaming as of late has been more difficult for some due to the combination of the high latency inherent to geostationary satellite internet and system congestion, which has increased as a result of so many more people being home, and online, because of the pandemic. And the reason I say "for some" is because the amount of congestion can vary from location to location. This isn't an excuse, but only an explanation.
A couple of things you can try are reducing the resolution of the streamed item, whether via the app being used or at the source, and turning off, or snoozing, the Video Data Saver, though how much either of these things may help will likely vary.
One other possible cause of the problem is your overall speed. If you'd like to troubleshoot the issue, the first step would be to make sure you are not out of plan data and throttled. You can check on the Home page of the HughesNet modem's System Control Center, or by signing into the HughesNet My Account site and clicking on the Usage Tab, or by checking with the HughesNet Mobile app, which you can get from Google Play or the App Store for Android and Apple devices, respectively. If you've been subscriber for a while and still have the now discontinued HughesNet Usage Meter installed, you can check with that as well. Lastly, for a quick check, you can click on "My Usage" on the upper right of any HughesNet Community page (while signed in to the community).
If you have plan data, the next step would be to run some speed tests to establish your service speed. The tests need to be run in a specific way. You can find the testing instructions here. Please be sure to thoroughly read them before running the tests to ensure that they are properly run. Also, you may notice a discrepancy in the testing sizes between what is shown in the main post and what is shown in the "in depth guide". Please use the test sizes shown in the main post (25MB for download and 4MB for upload).
Here's hoping the next ISP works for you. Good luck!
GabeU, thank you for your long reply. All you suggested has been done to no avail. Our contract runs out next month so will try another satellite service to hope to get better internet connection all around.
