Using the Cable Modem

Buttons

ON/OFF – Turns the modem on or puts it in standby mode. Placing the cable modem in standby mode (the “off” position) allows for continued status monitoring from the cable network. This also disconnects your computer from the Internet for added security.

Important: Do not press this button when transmitting data over the internet. The information will be lost and your Internet connection disabled.

LED/Light Indicators – Operational

Mode

POWER – Indicates whether the cable modem is in active or standby mode. The light is off when the modem is in standby mode, and on when the power is activated and in the operational mode.

PC LINK – Indicates whether the connection between the computer and the modem is active (ready to transmit/receive) or actually transmitting/receiving. The light is off when no carrier is present (or the modem is in standby mode), on when the carrier is present but there’s no transmit/receive activity, and flashing when there is transmit/receive activity.

CABLE – Indicates the status of your cable connection. The light is off when no cable connection is detected or the modem is in standby mode and fully lit when the modem is registered with the network and data can be sent.

ACTIVITY – Indicates the existence of data traffic in the cable lines.

The light is off when no data traffic is present and flashing when data activity exists.

EMAIL– This light flashes when you have mail (if available through service provider).

26

Note: If all of the lights are flashing sequentially, it means the cable modem is automatically updating its system software. Please wait for the lights to stop flashing. You cannot use your modem during this time. Do not remove the power supply or reset the cable modem during this process.

Using the Cable Modem

Reset Switch

The reset switch can be found behind a “toothpick hole” on the back panel. It performs two functions:

1.

Basic Reset – Press and release the switch to make it perform the same function as disconnecting the power from the modem. It will start up again in Initialization Mode, see page 25.

2.

Factory Default Reset – Unplug the modem from the AC power. Press and hold the reset switch while plugging the modem into AC power. Continue holding the switch. Release the switch when all lights come on (about 6 seconds). This will return the modem to a factory “out of box” condition.

This should only be done if the cable modem has been taken out of service in one location and is being reconnected to a different service, or if instructed to do so by your cable company.

Frequently asked questions

Q. What if I don’t subscribe to cable TV?

A.

If cable TV is available in your area, data service may be made available with or without cable TV service. Contact your local cable company for complete information on cable services, including high-speed internet access.

Q. How do I get the system installed?

A.

Professional installation from your cable provider is strongly recommended. They will ensure proper cable connection to the modem and your computer. However, your retailer may have offered a self installation kit, including the necessary software to communicate with your cable ISP.

Q. Once my DCM is connected, how do I get access to the Internet?

A.

Your local cable company provides your internet service*, offering a wide range of services including email, chat, and news and information services, and a connection to the World Wide Web.

Q. Can I watch TV and surf the Internet at the same time?

A.

Absolutely! And your phone line won’t be tied up while you’re online.

Q. Can I run more than one computer on the modem?

A.

Yes – a single cable modem can support up to 32 computers using Ethernet connectivity.**

Q. What do you mean by “Broadband”?

A.

Simply put, it means you’ll be getting information through a “bigger pipe,” with more bandwidth, than a standard phone line can offer. A wider, “broader” band means more information, more quickly.

Q. What is DOCSIS and what does it mean?

A.

“Data Over Cable Service Interface Specifications” is the industry standard that most cable companies are adopting as they upgrade their systems. Should you ever decide to move, the cable modem will work with all upgraded cable systems that are

DOCSIS-compliant.

* Monthly subscription fee applies.

** Additional equipment required. Contact your cable company and ISP for any restrictions or additional fees.

28

General Troubleshooting

I can’t access the internet or my email.

• Check all of the connections to your cable modem.

• Your Ethernet card or USB port may not be working. Check its documentation for more information.

• The Network Properties of your operating system may not be installed correctly or the settings may be incorrect. Check with your ISP or cable company.

Nothing happens when I press the on/off button.

• Make sure that the AC power supply is fully plugged into a wall outlet.

• Make sure that the power supply cord is fully inserted into the AC adapter connection on the back of the modem.

• Double-check that the AC outlet you are using is not controlled by a switch that is turned off.

All of the lights are flashing in sequence.

• This means the cable modem is automatically updating its system software. Please wait for the lights to stop flashing. The updating process typically lasts less than one minute.

• Do not remove the power supply or reset the cable modem during this process.

The light labeled “email” is flashing (if available).

• This means that you have new mail to check.

The light labeled “email” does not flash.

• This may mean that your service provider does not offer this feature.

29

General Troubleshooting

I can’t get the modem to establish an Ethernet connection.

• Even new computers don’t always have Ethernet capabilities – be sure to verify that your computer has a properly installed Ethernet card and the driver software to support it.

• Check to see that you are using the right type of Ethernet cable (see page 24).

The modem won’t register a cable connection (Cable light not on continuously).

• If the modem is in Initialization Mode, the Power Light will be flashing. Call your

Cable company if it has not completed this 5-step process within 30 minutes, and note which step it is getting stuck on. (See page 25 for details.)

• The modem should work with a standard RG-6 coaxial cable, but if you’re using a cable other than one your Cable company recommends, or if the terminal connections are loose, it may not work. Check with your Cable company to determine whether you’re using the correct cable.

• If you subscribe to video service over cable, the cable signal may not be reaching the modem. Confirm that good quality cable television pictures are available to the coaxial connector you are using by connecting a television to it. If your cable outlet is “dead” call your Cable company.

• Verify that the cable modem service is DOCSIS-compliant by calling your cable provider.

Professional installation from your cable provider is strongly recommended. They will ensure proper cable connection to the modem and your computer. However, your retailer may have offered a self installation kit, including the necessary software to communicate with your cable ISP.
Can I watch TV and surf the Internet at the same time?
Absolutely! And your phone line won’t be tied up while you’re online.
Can I run more than one computer on the modem?
Yes – a single cable modem can support up to 32 computers using Ethernet connectivity.
What do you mean by “Broadband”?
Simply put, it means you’ll be getting information through a “bigger pipe,” with more bandwidth, than a standard phone line can offer. A wider, “broader” band means more information, more quickly.
What is DOCSIS and what does it mean?
“Data Over Cable Service Interface Specifications” is the industry standard that most cable companies are adopting as they upgrade their systems. Should you ever decide to move, the cable modem will work with all upgraded cable systems that are DOCSIS-compliant.
