You may very well need a tech visit to re-point and tighten down your dish.
The reps are on M-F from approximately 9AM to 6PM EST. They usually respond within a working day, so hopefully you'll see a reply from one tomorrow.
In the meantime, it would be best for you to leave the HughesNet modem plugged in so that the reps can attempt remote diagnostics on your HughesNet equipment, even though it may not be possible for them to do so from the sound of it.
Thank you for reaching out, I would be happy to assist you regarding this issue. Please send me a private message with the SAN or the phone number registered to the account.
