Where Is the Best Location for My Cable Modem?
Where Is the Best Location for My Cable Modem?
The ideal location for your cable modem is where it has access to outlets and other
devices. Think about the layout of your home or office, and consult with your
service provider to select the best location for your cable modem. Read this user's
guide thoroughly before you decide where to place your cable modem.
Consider these recommendations:
Position your PC and cable modem so that they are located near an AC power
outlet.
Position your PC and cable modem so that they are located near an existing cable
input connection to eliminate the need for an additional cable outlet. There
should be plenty of room to guide the cables away from the modem and the PC
without straining or crimping them.
Airflow around the cable modem should not be restricted.
Choose a location that protects the cable modem from accidental disturbance or
harm.

How Do I Set Up My High-Speed Internet Access Account?
How Do I Set Up My High-Speed Internet Access Account?
Before you can use your cable modem, you need to have a high-speed Internet
access account. If you do not have a high-speed Internet access account, you need to
set up an account with your local service provider. Choose one of the two options in
this section.
I Do Not Have a High-Speed Internet Access Account
If you do not have a high-speed Internet access account, your service provider will
set up your account and become your Internet Service Provider (ISP). Internet access
enables you to send and receive e-mail, access the World Wide Web, and receive
other Internet services.
You will need to give your service provider the following information:
The serial number of the modem
The Media Access Control (MAC) address of the modem
These numbers appear on a bar code label located on the cable modem. The serial
number consists of a series of alphanumeric characters preceded by S/N. The MAC
address consists of a series of alphanumeric characters preceded by MAC. The
following illustration shows a sample bar code label.
Write down these numbers in the space provided here.
Serial Number _______________________
MAC Address ________________________
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.
