For Comcast XFINITY Users Only: If the activation page does not appear in your browser, please go to www.xfinity.com/internetsetup for more information and to activate your modem. If no registration page appears after following the browser instructions above, you need to contact your cable company to register your modem. Here is a list of phone numbers for some major cable service providers. (Note that this list is subject to change.) Comcast 1 (855) 652-3446 Time Warner 1 (855) 704 4503 Bright House 1 (888) 289-8988 Suddenlink 1 (877) 794-2724 Cable One 1 (877) 692 2253 Cox 1 (888) 556-1193 RCN 1 (866) 832-4726 Once your cable modem is registered either online or by phone, your service provider will provision your cable modem service. Typically this takes less than 5 minutes, but in some cases this may take 30 minutes or longer to complete. Once you have activated, you should have Internet access for whatever's plugged into your cable modem. Congratulations! If your cable modem is NOT working, see Troubleshooting Tips below.
