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.

What Are the System Requirements for Internet Service?

To ensure that your cable modem operates efficiently for high-speed Internet service, verify that all of the Internet devices on your system meet or exceed the following minimum hardware and software requirements.

Note: You will also need an active cable input line and an Internet connection.

Minimum System Requirements for a PC

• A PC with a Pentium MMX 133 processor or greater

• 32 MB of RAM

• Web browsing software (Netscape or Internet Explorer)

• CD-ROM drive

Minimum System Requirements for Macintosh

• MAC OS 7.5

• 32 MB of RAM

System Requirements for an Ethernet Connection

• A PC with Microsoft Windows 95 operating system (or later) with TCP/IP

protocol installed, or an Apple Macintosh computer with TCP/IP protocol installed

• An active 10/100BaseT Ethernet network interface card (NIC) installed PC

System Requirements for a USB Connection

• A PC with Microsoft Windows 98SE, ME, 2000, or XP operating system

• A master USB port installed in your PC or your Apple Macintosh computer

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 cable service provider. Choose one of the following two options.

I Do Not Have a High-Speed Internet Access Account

If you do not have a high-speed Internet access account, your cable 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. When you contact your cable service provider, they will ask you for the serial number and the Media Access Control (MAC) address of the cable modem.

These numbers appear on a label located on the side of 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 CM MAC. See the following illustration of a sample label.

I Already Have an Existing High-Speed Internet Access Account

If you have an existing high-speed Internet access account, you must give your cable 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 be able to continue to use your existing e-mail account with your cable modem. Contact your cable service provider for more information.

How Do I Connect My Devices to Use the Internet?

You can use your cable modem to access the Internet, and you can share that Internet connection with other Internet devices in your home or office. Sharing one connection among many devices is called networking.

Connecting and Installing Internet Devices

You must connect and install your cable modem to access the Internet. Professional installation may be available. Contact your local cable service provider for further assistance.

To install the cable modem for high-speed data service

1. Power off your PC and unplug it from the power source.

WARNING:

To avoid personal injury or damage to your equipment, follow these steps in the exact order shown.

2. Connect your PC to either the ETHERNET port or the USB port using the

appropriate data cable. Do not connect your PC to both the Ethernet and USB ports at the same time. You can connect two separate PCs to the cable modem at the same time by connecting one PC to the Ethernet port and one PC to the USB port.

3. Connect the active RF coaxial cable to the CABLE connector. Use an

optional cable signal splitter to add a TV, a DHCT or set-top converter, or a VCR.

4. Insert the AC power cord into the POWER connector on the back of the

cable modem, and then plug the cord into an AC power source.

5. Plug in and power on your networked devices including your PC. The

cable modem will then begin an automatic search to locate and sign on to the broadband data network. This process may take up to 5 minutes. The modem will be ready for use when the ONLINE LED status indicator on the front panel stops blinking and illuminates continuously.

6. The next step in setting up your cable modem is to configure your

Internet devices for Internet access. Choose one of the following options:

• If you want to use Ethernet connections, you must configure the TCP/IP protocol. To configure the TCP/IP protocol go to How Do I Configure TCP/IP Protocol, next in this guide.

• If you want to use USB connections, you must install the USB drivers. To install the USB Drivers for USB go to How Do I Install USB Drivers, later in this guide.

How Do I Configure TCP/IP Protocol?

To configure TCP/IP protocol, you need to have an Ethernet Network Interface Card (NIC) with TCP/IP communications protocol installed on your system. TCP/IP is a communications protocol used to access the Internet. This section contains instructions for configuring TCP/IP on your Internet devices to operate with the cable modem in Microsoft Windows or Macintosh environments.

Configuring TCP/IP on Your Internet Devices

TCP/IP protocol in a Microsoft Windows environment is different for each Windows version. Follow the appropriate instructions in this section for your operating system.

To configure Windows 95, 98, 98SE, or ME systems

1. Click Start, select Settings, and choose Control Panel.

2. Double-click the Network icon in the Control Panel window.

3. Read the list of installed network components under the Configuration tab to verify that your PC contains the TCP/IP protocol/Ethernet adapter.

4. Is TCP/IP protocol listed in the installed network components list?

• If yes, go to step 7.

• If no, click Add, click Protocol, click Add, and then go to step 5.

5. Click Microsoft in the Manufacturers list.

6. Click TCP/IP in the Network Protocols list, and then click OK.

7. Click the TCP/IP Ethernet Adapter protocol, and then choose Properties.

8. Click the IP Address tab, and then select Obtain an IP address automatically.

9. Click the Gateway tab and verify that these fields are empty. If they are not empty, highlight and delete all information from the fields.

10. Click the DNS Configuration tab, and then select Disable DNS.

11. Click OK.

12. Click OK when the system finishes copying the files, and then close all networking windows.

Click YES to restart your computer when the System Settings Change

13. dialog box opens. The computer restarts. The TCP/IP protocol is now

configured on your PC and your Ethernet devices are ready for use.

14. Try to access the Internet. If you cannot access the Internet, go to Having Difficulty, later in this guide. If you still cannot access the Internet, contact your cable service provider for further assistance.
