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

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!
