Items You Need
If ou are installing the Cable Modem ourself, make sure ou have the following
items on hand before continuing:
• Cable modem package : see What’s in the Box? for a list of items in the
package.
• Coaxial cable (coax) : as shown in the picture to the left, this is a thin ca-
ble with a connector on each end. It is the same kind of wire used to connect
our television for cable TV. You can bu coax from an electronics retailer
and man discount stores; make sure it has connectors on both ends.
(There are two t pes of connectors, slip-on and screw-on; the screw-on
connectors are best for use with our Cable Modem.) The coax should be
long enough to reach from our Cable Modem to the nearest cable outlet.
• plitter (optional) : provides an extra cable connection b splitting a single
outlet into two. You ma need a splitter if ou have a TV alread connected
to the cable outlet that ou want to use. You can bu a splitter from an
electronics retailer and most discount stores; ou ma also need a short
piece of coaxial cable (with connectors); use it to connect the splitter to the
cable outlet and then connect the Cable Modem and TV to the splitter.
Note: A splitter effectivel cuts the signal in half and sends each half to its two
outputs. Using several splitters in a line ma slow down or stop Internet
communications, or cause snow TV pictures.
• Information packet : our cable compan should furnish ou with a packet
containing information about our service and how to set it up. Read this
information carefull and contact our cable compan if ou have an ques-
tions.

Ethernet or U B?
There are two wa s to connect our computer (or other equipment) to the Cable
Modem. The following will help ou decide which is best for ou:
Ethernet
Ethernet is a standard method of connecting two or more computers into a Local
Area Network (LAN). Use the Ethernet connection if our PC has built-in Ethernet
hardware, or does not use Windows, or ou want to share the Cable Modem con-
nection with several computers.
Note: To connect two or more computers to the Ethernet port, ou need a hub
or broadband router (available at computer retailers).
The Cable Modem package comes with a 6-foot (1.9m) Ethernet cable (the connec-
tors look like wide telephone connectors); ou can purchase more cables if neces-
sar at a computer retailer. If ou are connecting the Cable Modem directl to a PC,
or to an Ethernet hub or broadband router with a cross-over switch, ask for
Categor 5 (CAT5) straight-through cable. If ou are connecting the Cable Modem
to an Ethernet hub or broadband router without a crossover switch, ask for a Cat-
egor 5 crossover cable.
U B
USB (Universal Serial Bus) is meant for connecting a variet of accessories, such
as ke boards, mice, printers, and communications devices (including cable mo-
dems) to a single PC. Use the USB connection if ou have onl one computer, and
the computer is using a Windows operating s stem (Windows 98 Second Edition or
later), and has no built-in Ethernet hardware.
The Cable Modem package comes with a 5-foot (1.6m) USB cable; ou can pur-
chase a longer cable—up to 14-foot (4.25m)—at a computer retailer. Ask for a U B
A/B cable —it has a long narrow connector on one end (to connect to the PC) and
a square connector on the other end (to connect to the Cable Modem).
Both
If ou have two or more computers, ou can connect one computer to the Cable
Modem’s USB port and one or more to the Ethernet port. To connect two or more
computers to the Ethernet port, ou need a hub or broadband router (available at
computer retailers).
For more information about connecting two or more computers, contact our cable
service provider.

What About ecurity?
Having a high-speed, alwa s-on connection to the Internet requires a certain
amount of responsibilit to other Internet users—including the need to maintain a
reasonabl secure s stem. While no s stem is 100% secure, ou can use the fol-
lowing tips to enhance our s stem’s securit :
• Keep our operating s stem updated with the latest securit patches. Run
the s stem update utilit at least weekl .
• Keep our email program updated with the latest securit patches. In addi-
tion, avoid opening email containing attachments, or opening files sent
through chat rooms, whenever possible.
• Install a virus checker and keep it updated.
• Use the tandby button on our Cable Modem to disconnect our PC from
the cable s stem when ou are not using the Internet.
• Avoid providing web or file-sharing services over our Cable Modem. Be-
sides certain vulnerabilit problems, most cable companies prohibit running
servers on consumer-level accounts and ma suspend our account for vi-
olating our terms of service.
• Use the cable compan ’s mail servers for sending email.
• Avoid using prox software unless ou are certain that it is not open for
abuse b other Internet users (some are shipped open b default). Crimi-
nals can take advantage of open proxies to hide their identit when breaking
into other computers or sending spam. If ou have an open prox , our ca-
ble compan ma suspend our account to protect the rest of the network.
• If ou connect our Cable Modem to a wireless LAN, make sure ou enable
securit and encr ption on the wireless hub (for the same reason that ou
should run onl secured proxies). Consult the documentation and technical
support of the wireless equipment provider for help.
