Brand new Apple TV--issues with "Accessing Netflix" freezing

Hi--We just purchased an Apple TV on Monday. Every evening that we've used it this week--it's now Friday--it freezes with an "Accessing Netflix" issue. We have to log out of everything and restart it. Every day. Could this be a wifi issue--solvable if we connect with an Ethernet? Is this a Netflix issue? Or is this an Apple TV issue--maybe we received a defective one? I can't believe that it's normal to have to restart this thing every day. Thanks for suggestions.
