Sz, thank you for providing this information. In order to resolve this, we will need you to perform a re-registration of the HughesNet modem to continue troubleshooting. Please give us a call at 866-347-3292 so that we can walk you through the steps. I will leave details in your account so the agent knows what steps need to be taken.
Glad you got it fixed and you're up and running again. Years ago I had to have the same thing replaced on my old setup. My internet wasn't fully down like yours was, but it kept giving me all kinds of intermittent connection issues.
