Have you activated your new modem? If not, try:
Before you start, make sure your account number and telephone number are readily available. This information can be found on your monthly statement or order confirmation e-mail.
If the online activation does not succeed, call customer support: 1-800-COMCAST (1-800-266-2278) or 1-800-XFINITY (1-800-934-6489)
Or Try calling 1-855-652-3446. That is their device activation line.
