Trying to set up modem. 

Best answer by SURFboard Moderator

For your information, the SB8200 is a cable modem and does not include any Wi-Fi features. It is a plug-and-play device. If you are setting up the SB8200, you will need a separate router to enable Wi-Fi, as the router provides the Wi-Fi functionality.

If you are activating a new SB8200, you could using the self-activation method through the Xfinity app.
