Items You Need
If you are installing the Wideband Cable Modem yourself, make sure you have the
following items on hand before continuing:
• Wideband Cable Modem package: see What’s in the Box? for a list of
items in the package.
• Coaxial cable (coax): as shown in the image to the left, this is a thin cable
with a connector on each end. It is the same kind of wire used to connect to
your television for cable TV. You can buy coax from any electronics retailer
and many discount stores; make sure it has connectors on both ends. There
are two types of connectors, slip-on and screw-on; the screw-on connectors
are best for use with your Wideband Cable Modem. The coax should be long
enough to reach from your Wideband Cable Modem to the nearest cable outlet.
• Splitter (optional): provides an extra cable connection by splitting a single outlet into two. You may need a splitter if you have a TV already connected to the cable outlet that you want to use. You can buy a splitter from
any electronics retailer and most discount stores; you may also need a short
piece of coax cable (with connectors); use it to connect the splitter to the
cable outlet and then connect the Wideband Cable Modem and TV to the
splitter.
Note: A splitter effectively cuts the signal in half and sends each half to its
two outputs. Using several splitters in a line may deteriorate the quality of
your television and/or internet connection.
• Information packet: your cable company should furnish you with a packet
containing information about your service and how to set it up. Read this information carefully and contact your cable company if you have any questions.

Ethernet or USB?
There are two ways to connect your computer (or other equipment) to the Wideband Cable Modem. The following will help you decide which is best for you:
Ethernet
Ethernet is a standard method of connecting two or more devices into a Local Area
Network (LAN). Use the Ethernet connection if your computer has built-in Ethernet
hardware, does not use Windows, or you want to share the Wideband Cable Modem
connection with several computers.
Note: To connect two or more computers to the Ethernet port, you will need a
hub or broadband router (available at computer retailers).
The Wideband Cable Modem package comes with a 6-foot (1.9m) Ethernet cable
(the connectors look like wide telephone connectors); you can purchase a longer
cable if necessary at a computer retailer. If you are connecting the Wideband Cable
Modem directly to a computer, or to an Ethernet hub or broadband router with a
cross-over switch, ask for Category 5 (CAT5) straight-through cable. If you are connecting the Wideband Cable Modem to an Ethernet hub or broadband router without a crossover switch, ask for a Category 5 crossover cable.
USB Cable
USB
USB (Universal Serial Bus) is meant for connecting a variety of accessories, such as
keyboards, mice, printers, and communications devices (including Wideband Cable
Modems) to a single computer. Use the USB connection if you have only one computer, and the computer is using a Windows operating system (Windows 2000 or
later), and has no built-in Ethernet hardware. Wideband Cable Modems with USB
ports include a 5-foot (1.6m) USB cable.
Both
If you have two or more computers, you can connect one computer to the Wideband Cable Modem’s USB port and one or more other computers to the Ethernet
port. To connect two or more computers to the Ethernet port, you will need a hub
or broadband router (available at computer retailers).
For more information about connecting two or more computers, contact your cable
service provider.

What About Security?
Having a high-speed, always-on connection to the Internet requires a certain
amount of responsibility to other Internet users—including the need to maintain a
reasonably secure system. While no system is 100% secure, you can use the following tips to enhance your system’s security:
• Keep your operating system updated with the latest security patches. Run
the system update utility at least weekly.
• Keep your email program updated with the latest security patches. In addition, avoid opening email containing attachments, or opening files sent
through chat rooms, whenever possible.
• Install a virus checker and keep it updated.
• Avoid providing web or file-sharing services over your Wideband Cable
Modem. Besides certain vulnerability problems, most cable companies prohibit running servers on consumer-level accounts and may suspend your account for violating your terms of service.
• Use the cable company’s mail servers for sending email.
• Avoid using proxy software unless you are certain that it is not open for
abuse by other Internet users (some are shipped open by default). Criminals can take advantage of open proxies to hide their identity when breaking into other computers or sending spam. If you have an open proxy, your
cable company may suspend your account to protect the rest of the network.
• If you connect your Wideband Cable Modem to a wireless LAN, make sure
you enable security and encryption on the wireless hub (for the same reasons that you should run only secured proxies). Consult the documentation
and technical support of the wireless equipment provider for help.
