Technical problems on x1 system, recordings and system refreshes required daily

Technical problems on x1 system, recordings and system refreshes required daily. This has been ongoing since they switched me over to the X1 system. The problem appeared right away in April of 2021 and only was resolved yesterday January 29, 2023! The problem was incompatibility with my own modem [spec'd by Xfinity as "compatible"] and the X1 tv boxes. There apparently is a problem that nobody in all of Comcast knew about until a smart technician who had learned of this and proposed it as a solution; removing the remote X1 boxes and streaming online with Smart TVs or Firestick allows the deletion of the boxes as well as their cost.
