Right now the system is under incredible strain because of the much higher pandemic related load. Speeds are taking a hit for pretty much everyone right now.
As well, HughesNet has implemented a prioritization policy that favors schooling and work related activities during high load periods, which is increasingly becoming around the clock as of recent. Because of this policy, streaming and gaming related activities may be harder to do and downloads for such may take much longer than they normally would.
Though it's not a fix, and there really isn't one right now, I hope this helps to explain a bit about why you're seeing your speeds take a bit of a hit.
