We lost Wi-Fi, telephone, and Xfinity TV yesterday. Xfinity could not help us over the phone. They sent out a tech. He could not pinpoint the problem. He ended up replacing our cable box. Now, we can no longer access AppleTV. When I try to pull it up, I am told that I need to purchase new equipment even though or an old cable box was sufficient for Apple TV. Our Wi-Fi remains glitchy. We have been on the phone, on hold or meeting with a tech for over five hours yesterday. We need some assistance. How do we get that?
