I see it's your first post here, so welcome to the community! We'd like to help. So we can begin addressing your speed concerns, please create a testmy.net account and run 3 tests when you normally experience a slow down. Post your test results link here in your thread.
Most important points to remember during this test:
-do the tests while directly connected to the HughesNet modem with a LAN cable (this way your Hopper and multiple Amazon devices don't interfere with testing)
-use the 25MB size download 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
For a more in depth guide on running the tests, please visit: http://customer.kb.hughesnet.com/Pages/7001.aspx
Your cooperation, patience, and understanding are much appreciated.
