It's possible that there is weather at your gateway that is affecting your service.
To determine the location of your gateway, what is the Satellite Name and Beam ID in the Satellite box on the following page? http://192.168.0.1/#!/home/information
If your location was not affected by adverse weather conditions prior to this, we'll need to know a little more information before moving forward. Using the link provided by GabeU, click on "System Status" at the top of that page. Towards the middle of the page will be a set of numbers labeled as the System State Code - please post that set of numbers here (will look something like 1.2.3).
Just checking in, it has been about a week since we received your post. If you are still experiencing any issues please reply here at your earliest convenience. I will be closing this thread next Wednesday.
