I noticed that the results from the "Living Room" device are considerably better than those from "Den/Study" device. It makes me wonder whether this is a WiFi signal issue at that "Den/Study" device. If the "Den/Study" device is connected via the 5GHz band, try changing it to the 2.4GHz band, which has better range.
You can test your the WiFi signal strength at your devices with the HughesNet Mobile App. The WiFi tester is the middle icon that comes up when tapping on the orange button on the lower right, or at least it is in the Android version of the App. Make sure the device you're testing with is connected to the same band as the device in which you're testing for. As an example, if your "Den/Study" device is connected via the 5GHz WiFi band, make sure your testing device, such as a smart phone, is also connected to that 5GHz band, and make sure to have the phone near that "Den/Study" device when testing the WiFi. The idea is to know the quality of the utilized WiFi signal in the immediate area of that "Den/Study" device. If the "Den/Study" device is connected via the 2.4GHz band, make sure to have the phone connected to the same band when running the WiFi test.
