Apple TV app internet issue

my Internet connection occasionally turns off when watching Apple TV app. Turns off for about 60 seconds at a time, happens about twice per hour. This only happens when streaming on the Apple TV app. All other apps are working fine. Is there a way to clear the cache or reboot, the Apple TV box, or any other recommendation? I contacted my Internet provider, everything is working fine, speed is very good, etc. The only time I have any streaming issues is when using the Apple TV app.
