Hi Liz,
Thank you for your attention to this issue. I just got off the phone with Home Tech Support and the agent let me know that the Hughesnet engineers are aware of this problem and are working to resolve it, then I found this post in the Hughesnet community forums.
My issue is (I believe) related to the same thing that people in this post are complaining about, however, I'm using a MacBook Air and iPhone SE and specifically a feature built into all recent Apple products called Continuity.
As long as both my MacBook and my iPhone are on the same network, Continuity allows me to see every text message on my Macintosh as they come into my iPhone. I can also take (or place) phone calls directly from my Macintosh through its Continuity connection to my iPhone.
Like all the others in this post, these features stopped working approximately ten days ago (Feb. 7th or so) only when I am at home. Up until then, all these features worked flawlessly when I'm at home using my Hughesnet internet connection.
When I am at my office, these Apple Continuity features have worked and continue to work flawlessly.
My wife has a different iPhone and MacBook and she has experienced the same issues. Apple Continuity features worked perfectly at home and at work until about ten days ago when they stopped working
only at home when using our Hughesnet network.
I'm sure your engineers are working with Apple engineers. I'm not sure if the issues described in this post from Apple (

Thanks!
