I have a Samsung QLED TV connected to my router via ether-net cable for stability. If I stream my home videos, photos etc to the TV it connects fine but cuts off after about 20 minutes, with the swirling disc, eventually leading to a reconnect message. I'm thinking the issue is with the TV as, I've tried it with a Panasonic TV, via WiFi & this doesn't happen. My only thought is there may be something in the router settings that could affect the wired only connection. Any thoughts.
