Information: Cable Modem Overview
► Summary:
The following information supplies resources to the cable modem.
► Content
Generally, we will be responsible for installing a new cable drop near your computer. We also will
install the cable modem, if you prefer. To perform the setup yourself, or you decide later to move your
computer, follow these instructions.
Cable Modem Lights
External cable modems have front panel indicator lights that show the status of the cable Internet
connection. The exact labels for these lights will vary between manufacturers, but all external cable
modems have lights that indicate similar information. During installation you'll need to use the
information provided by these indications.
One light indicates when power is available and the modem is turned on. Another light indicates a
connection (block sync or synchronization) with the cable network. One light will indicate a working
connection to your PC. Another light (or two) will flash to indicate that data is being transferred--if
there are two such lights, one light flashes when your modem sends data and the other flashes when
your modem receives data. Some modems have a test light or one that indicates a modem error.
NOTE: Plug your cable modem into a surge-protected 110-volt power strip. The cable modem must
always be in an open, well-ventilated area. Do not put the cable modem in a confined space or place
books, files or other desktop paraphernalia on or next to it.
After the completion of each installation step, you must check the modem lights for the proper
indications. If, after any one of these steps, you don't get the proper indication, do not proceed any
further. Contact Suddenlink High Speed Internet Customer Support.
Now proceed to the appropriate section for the type of cable modem connection you will use: Ethernet
Cable Modem Installation Ethernet
These instructions assume that your computer has a working Ethernet port.
Begin installation by connecting the cable drop to the back of the cable modem.
1. Attach one end of the power adapter into the power input on the modem. The other end plugs
into a standard 110-volt outlet.
2. Powering up the cable modem could take longer the first time (from 2 to 10 minutes) than on
successive occasions because it must establish its initial connection (block sync or
synchronization) to Suddenlink High Speed Internet.
3. Connect one end of a standard network cable into the Ethernet port of the NIC that is installed
in your computer. The Ethernet port looks like a large telephone jack.
4. Insert the other end of the network cable into the Ethernet port on the back of the cable
modem.
Once the modem has established its connection to Suddenlink High Speed Internet, you will usually
have three lights on (power, cable and computer connection) showing that high-speed cable Internet
access is available to your computer. Next you'll install the Suddenlink High Speed Internet software
and your computer will be ready to go.
Cable Modem Installation - USB
These instructions assume that your computer has a working USB port and that you have an approved
USB-Ethernet adapter.
1. Begin installation by connecting the cable drop to the cable terminal on the back of the cable
modem.
2. Attach one end of the power adapter into the power input on the modem. The other end plugs
into a standard 110-volt outlet.
3. Powering up the cable modem could take longer the first time (from 2 to 10 minutes) than on
successive occasions because it must establish its initial connection (block sync or
synchronization) to Suddenlink High Speed Internet.
4. NOTE: Turn on your computer, make sure it's operating properly, and then verify that the USB
drivers provided support your operating system.
5. Plug one end of the USB cable into the USB port on the back of the modem.
6. Plug the other end of the USB cable into the USB port on your computer.
7. Insert the USB Drive CD when prompted by the operating system and follow the on-screen
instructions as the CD runs.
Once the modem has established its connection to Suddenlink High Speed Internet, you will usually
have three lights on (power, cable and computer connection) showing that high-speed cable Internet
access is available to your computer. Next you'll install the Suddenlink High Speed Internet software
and your computer will be ready to go.
