I have Spectrum cable and they are going Diditial. I installed a Roku on a TV that just has the cable attached direct in the back ( no cable box) Install was easy but when I go to the spectrum App and have all the channels I am not able to change channels. What can be done??
Do you have a cable box on another set?
If so , reset both the modem and cable box
What does the roku tell you when you're trying to change channels?
Do you have a modern router after the modem?
