Hello dlc1265, thank you for reaching out. I pulled up your account and I'm seeing the Nest is connected with a good signal quality on our end, along with another device that's connected also, which tells me that there's no issues with the HughesNet equipment connectivity-wise.
However, I researched your device a bit to better understand the situation through their website to look for any compatibility issues, Wi-Fi interference, or anything else that may be disconnecting your Nest. I checked to make sure your ping and signal were within the necessary numbers in order for your Nest to work properly, and everything checked out there as well.
The Nest's website states, "Try using WPA2 encryption on your router when using Nest products. You can also try using WEP or WPA encryption if you're having trouble getting your products to connect." One thing you can try is adjusting your Wi-Fi settings through the System Control Center (Note: To access this page you will need to be connected to your HughesNet Wi-Fi). The password to access your settings page will be admin and you'll see there's a WPA mode, which is normally set onto WPA2, and you can change it there.
The website does provide troubleshooting that I reviewed to look for some answers, but there isn't much that can be done without being at home. So the next step I would recommend is contacting Nest to see if they can do anything remotely on their end.
If you have any questions, please don't hesitate to ask!
