Hi, @user_boansw I'm sorry to hear that when you replaced your box, nothing is working. If your new Xfinity box isn't working, immediately check that all cables especially the coax cable from the wall are securely connected. Most new boxes need to be activated via the Xfinity app or online, and may require 15–20 minutes to sync and receive signals. Are you getting any error message?
