I had Xfinity Internet for a year and then switched to the Internet/TV package. I already have the Internet router. Do I have to take it back and get a digital box. There is no HDMI on this box. Thank you for your help.
You have an old cable box. I certainly would upgrade to a new box with all the digtal capabilities that are available. Take it in to the local,Comcast office and they will trade you up for no extra fee.
