I recently got a new router and TV set top box from Verizon. Now I frequently have the set top box lose internet connection. And I can’t stream. The cable still works and I can stream thru my PC and phone and iPad but not the TV. I have to reset everything and then re-add all my apps like Netflicks, Apple TV, etc. which is a major pain and time consuming. I have a Samsung TV and a Yamaha receiver . I also can’t get sound thru my home theater anymore, just the TV. It worked briefly once when I unplugged everything . The home theater is hard wired. Is this a defective tv set box?
