*I am not a Hughesnet employee or representative. This is a customer-to-customer tech support community, and I am a customer.
I see it's your first post here, so welcome to the community! To piggyback on what maratsade said:
We understand this is a difficult period for many of our customers affected by recent events. HughesNet has implemented numerous prioritization enhancements focused on education applications/websites and, for those working at home, many popular business and communication apps.
While it may not be immediately apparent, HughesNet, like all Internet Service Providers, is experiencing increased network traffic, which is likely to be a contributing factor to your issues with streaming. Currently, our engineers are working around the clock to keep our network stable and traffic flowing as smoothly as possible for all our customers.
This type of problem typically does not require a visit from a technician or any configuration changes of the HughesNet equipment to see an improvement. However, there are some steps you can take to adjust the settings of your streaming application or device which may help improve your streaming experience. Check out the bottom of this message for a set of links for the more popular apps/devices and their respective support pages.
If you still do not see any improvement after adjusting your streaming app/device settings, please check the following HughesNet support articles.

Streaming App Settings:
Netflix, Hulu, Amazon Prime, YouTube, Facebook, Tumblr, Instagram, news sites, etc. may contain videos, animated gifs, and sound clips that start playing, therefore that entire video may have already downloaded to your device. Make sure you’re using the latest version of the streaming app. Not all sites have a feature to turn off auto-play.
