No, but you would need a cable box, DVR, or digital adapter for each TV set. Except when used with beta Roku steaming, your modem/router provides Internet access, not TV service.
Hello pawyatt_0315, the information that (BruceW) shared is correct. You will not need to update your modem, but a cable box is required unless you sign up for stream services only. You can change your plan online or just shop around and see what deals you can put together, please reach back out to me here if you have any additional questions or concerns.
