Definitely don't use the reset button on the back of the modem, as a modem reset can actually make things worse if it's done improperly or in the wrong instance. A modem reset should only be done under the instruction of a HughesNet rep, and then only in the manner they instruct.
Though there is occasionally one on during the evening, the reps are normally on M-F from approximately 9AM to 6PM EST. They usually reply within a working day, so you should hear from one tomorrow. Make sure to leave the modem plugged in so that the reps can run remote diagnostics on your HughesNet equipment if they deem it necessary, which they very likely will. Hopefully it's something that they can fix remotely. 🙂
Thank you for reaching out to us and welcome to the community. I am sorry to hear you are experiencing this. Because we do not currently have communication with your modem remotely, we will need a little bit of help from your end if that is ok with you. Once we have this, we can provide the correct assistance for this issue.
In order to find out what is happening to the service, we will need to obtain the state code. If you see lights on the modem where "WiFi" or "LAN" are labeled, you will be able to access the modem's control center. This is where we will be able to locate the state code. To do this, open any browser you would like on a computer or device connected to your HughesNet modem. In the address bar at the top of the page, type in 192.168.0.1 or systemcontrolcenter.com. This will populate the control center for your modem. At the top of the page, please click on the "System Status" link. The next page will load where the state code will be displayed in the first information box. Your state code should be in a format such as "0.0.0". Once you find your specific state code, please post it here so that we can continue with the next troubleshooting steps.
I'm glad you were able to get through and get what you needed. 🙂
