Getting to Know the Cable Modem with USB and Ethernet Connection
Overview
A cable modem is a device that allows high-speed data access (such as to the
Internet) via a cable TV network. A cable modem will typically have two
connections, one to the cable wall outlet and the other to a computer (PC).
The fact that the word “modem” is used to describe this device can be a little
misleading only in that it conjures up images of a typical telephone dial-up
modem. Yes, it is a modem in the true sense of the word since it MOdulates and
DEModulates signals. However, the similarity ends there, as these devices are
much more complicated than telephone modems. Cable modems can be part modem,
part tuner, part encryption/decryption device, part bridge, part router, part
network interface card, part SNMP agent, and part Ethernet hub.
Cable modem speeds vary, depending on the cable modem system, cable network
architecture, and traffic load. In the downstream direction (from the network
to the computer), network speeds can reach 27 Mbps, an aggregate amount of
bandwidth that is shared by users. Few computers will be capable of connecting
at such high speeds, so a more realistic number is 1 to 3 Mbps. In the
upstream direction (from computer to network), speeds can be up to 10 Mbps.
Check with your Cable Internet Service Provider (ISP) for more specific
information about upload (upstream) and download (downstream) access speeds.
In addition to speed, there’s no need to dial in to an ISP when you are using
your Cable Modem. Simply click on your browser and you’re on the Internet. No
more waiting, no more busy signals.

-
cannot access my e-mail or Internet service
Make sure all of your connections are secure. Your Ethernet cable should be inserted completely into both the network card on the back of your computer and the port on the back of your Cable Modem. If you installed your Cable Modem using a USB port, check the connection of the USB cable to both devices. Check all cables between your computer and the
Cable Modem for frays, breaks or exposed wiring. Make sure your power supply is properly plugged into both the modem and a wall outlet or surge protector. If your Cable Modem is properly connected, the Power LED and Cable LED on the front of the modem should both be a solid color.
The Link/Act LED should be solid or flashing.
Try pressing the Reset button on the back of your cable modem. Using an object with a small tip, push the button until you feel it click. Then try reconnecting to your Cable ISP.
Call your Cable ISP to verify that their service is two-way. This modem is designed for use with two-way cable networks.
If you installed the Cable Modem using the Ethernet port, make sure that your Ethernet adapter is operating correctly. Check the adapter in the
Device Manager in Windows to make sure it is listed and has no conflicts.
If you are unsure of how to do this, check your Windows documentation.
Make sure that TCP/IP is the default protocol in use by your system. See the section called Installing the TCP/IP Protocol for more information.
If you are using a cable line splitter so that you can connect the cable modem and a television at the same time, try removing the splitter and reconnecting your cables so that your Cable Modem is connected directly to your cable wall jack. Then try reconnecting to your Cable ISP -
The Cable Status LED never stops blinking.
Has the Cable Modem’s MAC address been registered with your ISP? In order for your Cable Modem to be operational, you must call and have the ISP activate the modem by registering the MAC address from the label on the bottom of the modem.
Make sure that the Coax cable is firmly attached between the Cable Modem and the wall jack.
The signal from your cable company’s equipment may be too weak or the cable line may not be properly attached to the Cable modem. If the cable line is properly connected to the Cable modem, call your cable company to verify whether or not a weak signal may be the problem. -
All of LEDs on the front of my modem look right, but I still can’t access the Internet
If the Power LED, Link/Act, and Cable LEDs are on but not blinking, your cable modem is operating properly. Try shutting down and powering off your computer and then turning it back on. This will cause your computer to re-establish communications with your Cable ISP.
Try pressing the Reset button on the back of your cable modem. Using an object with a small tip, push the button until you feel it click. Then try reconnecting to your Cable ISP.
Make sure that TCP/IP is the default protocol in use by your system. See the section called Installing the TCP/IP Protocol for more information. -

Select the Ethernet adapter to show the IP address. Press Release and then press Renew to get a new IP address from your ISP’s server.
-
Select the OK to close the IP Configuration window. Try your Internet connection again after this process.
For Windows NT, 2000 or XP users:
-
From your Windows NT or 2000 desktop, click the Start button, point to Run, and click to open the Run window (see Figure C-1.)
-
Enter cmd in the Open field. Click the OK button to execute the program. The next window to appear will be the DOS Prompt window.
-
At the prompt, type ipconfig /release to release the current IP addresss. Then type ipconfig /renew to get a new IP address.
