The delay is normal with satellite communications, you will see approximately 600ms in delay between you, and the other party on your voice service.
As far as buffering goes, make sure that you set your resolution to Auto-Detect, or, at most, 480p. Alternatively, if you wish to watch videos in 720p or 1080p, you must disable the Video Data Saver option, as this throttles video stream connections to help save data. You can read more on what the Video Data Saver is, and how to disable it here.
Another thing you will want to keep in mind is if you exhaust your data, your speeds will be decreased to approximately 1Mbps or slower.
As far as speeds and how fast websites load, because of latency, websites will feel sluggish to load, however, the data is transmitted at the highest speed possible at any given time. If you wish to troubleshoot your speeds after taking the first few things into account, then please create a testmy.net account and perform 3-5 tests during different parts of the day. Then share the account results link with us here.
Tests from other sites like speedtest.net are not accepted due to the compression technologies and latency that are seen on satellite communications.
Most important points to remember during this test:
-do the tests while directly connected to the HughesNet modem with a LAN cable (NO third party Router or Wireless devices can be used)
-use the 25MB size download test file ONLY
-If testing upload instead of download, you must use a 4MB size upload test file
-space each test at least 5 minutes apart
-post your results URL here, it may look something like http://testmy.net/quickstats/C0RR0SIVE
