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
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

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.

How Do I Mount the Modem on a Wall? (Optional)
You can mount the cable modem on a wall using two wall anchors, two screws, and
the mounting slots located on the unit. The modem can be horizontally mounted.
Before You Begin
Before you begin, choose an appropriate mounting place. The wall can be made of
cement, wood, or drywall. The mounting location should be free of obstructions on
all sides, and the cables should be able to easily reach the cable modem without
strain. Leave sufficient clearance between the bottom of the cable modem and any
flooring or shelving underneath to allow access to cabling. In addition, leave enough
slack in all cables so that the cable modem can be removed for any required
maintenance without disconnecting the cables. Also, verify that you have the
following items:
Two wall anchors for #8 x 1 inch screws
Two #8 x1 inch pan head sheet metal screws
Drill with a 3/16-in. wood or masonry bit, as appropriate for the wall

software is properly installed. If you purchase and install an Ethernet card,
follow the installation instructions very carefully.
Verify the status of the front panel status indicator lights.

If you are connecting multiple PCs to the cable modem, you should first connect the
modem to the uplink port of the hub using the correct crossover cable. The LINK
LED of the hub will illuminate continuously.

The modem works with a standard 75-ohm RF coaxial cable. If you are using a
different cable, your cable modem will not function properly. Contact your cable
service provider to determine whether you are using the correct cable.

Tips for Improved Performance
Tips for Improved Performance
Check and Correct
If your cable modem does not perform as expected, the following tips may help. If
you need further assistance, contact your service provider.
Verify that the plug to your cable modem AC power is properly inserted into an
electrical outlet.
Verify that your cable modem AC power cord is not plugged into an electrical
outlet that is controlled by a wall switch. If a wall switch controls the electrical
outlet, make sure the switch is in the ON position.
Verify that the POWER and ONLINE LED status indicators on the front panel of
your cable modem are illuminated.
Verify that your cable service is active and that it supports two-way service.
Verify that all cables are properly connected, and that you are using the correct
cables.
Verify that your TCP/IP is properly installed and configured if you are using the
Ethernet connection.
Verify that you have followed the procedures in How Do I Install USB Drivers?
Verify that you have called your service provider and given them the serial
number and MAC address of your cable modem.
If you are using a cable signal splitter so that you can connect the cable modem
to other devices, remove the splitter and reconnect the cables so that the cable
modem is connected directly to the cable input. If the cable modem now
functions properly, the cable signal splitter may be defective and may need to be
replaced.
For best performance over an Ethernet connection, your PC should be equipped
with a 10/100BASE-T network interface card.
