Intermittent cutting out of sound and all video—or sometimes on live tv repeating short segments over and over again.

Good morning @user_l6a73u, and thanks for reaching out to us on the Xfinity forums, I hope this message finds you well. I am sorry to hear about the issues you are having with the cable service, I know how frustrating that can be, but you have come to the right place for assistance with this issue. Do you watch TV on a cable box, our using the Xfinity Stream app?
