Items You Need

If you are installing the Cable Modem yourself, make sure you 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 cable with a connector on each end. It is the same kind of wire used to connect 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 Cable Modem.) The coax should be long enough to reach from your 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 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:

Coax Cable

A splitter effectively cuts the signal in half and sends each half to its two outputs. Using several splitters in a line may slow down or stop Internet communications, or cause snowy TV pictures.

• 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 Cable Modem. The following will help you decide which is best for you:

Ethernet

Ethernet is a standard method of connecting two or more computers into a Local Area Network (LAN). Use the Ethernet connection if your PC has built-in Ethernet hardware, or does not use Windows, or you want to share the Cable Modem connection with several computers.

Ethernet Cable

USB Cable

Note:

The Cable Modem package comes with a 6-foot (1.9m) Ethernet cable (the connectors look like wide telephone connectors); you can purchase more cables if necessary at a computer retailer. If you are connecting the Cable Modem directly to a PC, 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 Cable Modem to an Ethernet hub or broadband router without a crossover switch, ask for a Category 5 crossover cable.

USB

USB (Universal Serial Bus) is meant for connecting a variety of accessories, such as keyboards, mice, printers, and communications devices (including cable modems) to a single PC. Use the USB connection if you have only one computer, and the computer is using a Windows operating system (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; you can purchase a longer cable—up to 14-foot (4.25m)—at a computer retailer. Ask for a USB

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 you have two or more computers, you 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, you need a hub or broadband router (available at computer retailers).

To connect two or more computers to the Ethernet port, you 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 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 pro 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 Cable Modem to a wireless LAN, make sure you enable security and encryption on the wireless hub (for the same reason that you should run only secured proxies). Consult the documentation and technical support of the wireless equipment provider for help.

Installing and Connecting Your Cable Modem

Before you start, make sure that:

•You have contacted your cable company and verified that they provide data service using standard DOCSIS technology.

•You have all the Items You Need.

• Cable and power outlets are available near the PC. If a cable outlet is not conveniently located, your cable company can install a new one.

Getting Service

Before trying to use your new Cable Modem, contact your local cable company to establish an Internet account. When you call, have the following information ready:

•the Cable Modem serial number and MAC address (printed on a sticker on the bottom of the Cable Modem)

•the model number of the Cable Modem

Save this information for future use. In addition, you should ask your cable company the following questions:

• Do you have any special system requirements or files that I need to download after I am connected?

• When can I start using my Cable Modem?

• Do I need a user ID or password to access the Internet or my e-mail?
