We've started having a problem with our 4 tuner Tablo where while watching a live show (doesn't matter what) at points the Tablo will start buffering (spinning square/circle). It will just get into this state and not come out on it's own. Sometimes we can get it to continue by pressing the Back button on our Firestick or AppleTV remote, which will superimpose the guide over the show, and the show restarts. Otherwise after a short period (20 to 40 seconds) a message appears saying that our Tablo has either been disconnected or assigned to another device. At that point press the select button the remote and it reconnects and starts up with the show or you have to power off the Tablo and restart it to fix the issue. The restart is a much smaller occurrence than just trying to start the show again.
We have 2 TV's, one with a Firestick and one with an AppleTV. The Tablo is directly wired to the network. There is a 2 TB hard drive hooked up which has been working great, recording the shows that we want recorded. Not sure what the problem is so if anyone has a suggestion as to why this might be happening and how to eliminate/prevent it from happening, please let me know.
