How Do I Set Up My High-Speed Internet Access Account?
I Already Have an Existing High-Speed Internet Access Account
If you have an existing high-speed Internet access account, you must give your
service provider the serial number and the MAC address of the cable modem. Refer
to the serial number and MAC address information listed previously in this section.
Note: You may not be able to continue to use your existing e-mail account with your
cable modem. Contact your service provider for more information.
