Introduction
Thank you for purchasing the D-Link “Broadba nd Ca ble Mode m with USB &
Ethernet” DCM-201, which is an MCNS DOCSIS™ 1.1 cable modem
featuring the latest DOCSIS technology.
The cable modem enables your network cable operator to provide you with
broadband applications such as telecommunications, IP dedication for your
small office/home office (SOHO), or high-speed residential Internet access.
The cable modem provides a downstream speed of up to 38 Mbps from the
cable network to your computer and 10Mbps from your computer to the cable
network.
The DES data encryption helps ensure privacy for the transmitted
information. Another distinctive feature of the cable modem is its easy
installation, because DHCP and TFTP clients can obtain automatic access
to the IP address and configuration from their network servers via the
modem. SNMP agents permit remote configuration and monitoring from a
management station equipped with an SNMP server.
7
Features
Full-featured compact, economical cable modem with Ethernet
and USB ports
DOCSIS 1.1-compliant
Capable of handling downstream data transmission speeds up to
38Mbps; upstream to 10Mbps
RJ-45 10/100BaseT Ethernet port provides traditional industrystandard connection
USB port allows easy plug-and-play attachment to PCs with the
latest Microsoft Windows operating system.
Extensive SNMP management support: MIB-II,
Ethernet-like MIB, Bridge MIB, Cable Device MIB,
Baseline privacy Interface MIB, RF Interface MIB
Easy-to-read front panel LED’s clearly display network status and
activity
Decide Which In stallation Proce ss to Use
The cable modem enables you to connect to the Internet using either your
computer’s Ethernet or USB port.
Be sure to follow the installation steps for the setup you want to use. Using
the Ethernet setup enables you to use a hub to connect multiple computers
to the cable modem. To do this, you might have to obtain additional IP
addresses from your cable operator.
Using the USB port enables you to install the cable modem more quickly and
easily than connecting to the Internet using the Ethernet port, because you do
not have to install a network interfa ce card (NIC) into your computer. The
USB port, however, only en ables you to connect one computer to the cable
modem.
See “Installing the Cable Modem Using the Ethernet Port”, or see “Installing
the Cable Modem Using the USB Port” in the following pages, for more
information.

connector. If you plan to have the cable connected to a television as
well as the cable modem, you must use a cable line splitter (not
included).
b Plug the cable modem’s power adapter into a wall outlet or surge
protector and into the cable modem’s power jack.
c Plug one end of the Ethernet cable into the cable modem’s Ethernet
port and the other end of the cable into the existing NIC.
4 Plug in the computer .
5 Power on the computer. When installation is complete, your setup should
resemble the illustration above. The modem is operating properly if the
Power, Cable, Status and ETH light emitting diode s (LEDs) are solid green
(lit and not blinking).
T roubleshooting the Ethernet In stallation
The following troubleshooting procedures apply to the Ethernet installation.
Problem: “I cannot access my e-mail or Internet service.”
1 Verify that the Power , Ca ble, Status, and Eth light-emitting diodes (LEDs)
are lit and not blinking.
2 Check all connections:
a Make sure the coaxial cable is securely connected to the cable jack
on the back of the cable modem.
b Verify that the Ethernet cable is securely plugged into both the
cable modem and the computer.
c Make sure the power adapter is properly plugged into both the
cable modem and a wall outlet or surge protector.
13
Problem: “I cannot access my e-mail or Internet service.” (continued)
3 Power cycle the cable modem by unplugging the power adapter from its
electrical outlet and then plugging it back into the outlet. Then try accessing
the Internet.
4 Power cycle the computer
a Power off the computer.
b Unplug the computer from its electrical outlet or surge protector and
then plug it back into the electrical outlet or surge protector.
c Restart the computer and try accessing the Internet.
5 Call your cable operator to verify that their service is two-way. This cable
modem is designed for use with two-way cable plants.
6 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 the cables so that the cable modem is connected directly to
the cable wall jack. Then try accessing the Internet.
7 The NIC might be malfunctioning. Refer to its documentation for
troubleshooting information.
8 Check for a resource conflict (Windows users only). To do this:
a Right-click the My Computer icon on the Windows desktop.
b Click Properties.
c Click the Device Manager tab and look for a yellow exclamation
point or red X over the NIC in the Network adapters field. If you see
either, you have an IRQ conflict. To correct this, refer to the
manufacturer’s documentation that came with your NIC.
9 Ma ke sure that TCP/IP is the default protocol in use by your computer.
a Release and renew the computer’s IP address.
To release and renew the IP address for the Windows 95, Windows 98,
and Windows Me operating systems:
1 Click Start and click Run.

address.
5 At the command prompt (C:\), type exit and press Enter to return to the
Windows desktop.
Problem: “All o f the LEDs on the front of my cable modem look right,
but I cannot access the Internet.”
1 If the Power , Ca ble, Status, and Eth (LEDs) are lit a nd not blinking the ca ble
modem is operating properly. Try shutting down the computer a nd then
turning it back on. This will cause the computer to re-establish
communications with your local cable provider.
2 Power cycle the cable modem by removing the power adapter from its
outlet and then plugging it back into the outlet. W ait several minutes for the
cable modem to re-establish communications with your local cable
operator, then try accessing the Internet.
3 Verify that you have installed TCP/IP properly (for Windows 95, Windows
98, Windows 98SE, and Windows Me: winipcfg; for Windows 2000 and
Windows XP: ipconfig), and that the TCP/IP parameters provided by your
local cable provider are correct for your computer.
4 If you are using a cable line splitter so that you can connect the cable
modem and a television to the same outlet:
a Try removing the splitter and reconnecting the cables so that the
cable modem is connected directly to the cable wall jack.
b Wait several minutes, then try accessing the Internet.
Problem: The power on my cable modem goes on and off sporadically.
You may be using the wrong power adapter. Check that the power adapter
you are using is the one that came with the cable modem.
CAUTION! You must use the 12VDC/1.25A power adapter that comes with
the D-Link DCM-201 cable modem. Using the wrong power adapter can
damage the cable modem.

Installing the Ca ble Modem Using the USB Port
CAUTION! Be sure to read this entire User’s Manual from front to back in
sequence before installing the DCM-201
This chapter describes how to install the cable modem using the USB port.
First you connect the hardware (cable modem and power adapter). You then
install the software drivers and verify that the mode m is operating properly.
The USB port does not support the Macintosh operating system.
Using the USB port to connect to the Internet enables you to install the cable
modem more quickly and e asily than connecting to the Internet using the
computer’s Ethernet port, because you do not have to remove the case from
the computer to install a network interface card (NIC). Using the USB port,
however, enables you to connect only one computer to the cable modem.
See “Installing the Cable Modem Using the Ethernet Port” if you wish to
install the cable modem using the Ethernet port.
Installing the Hardware (Ca ble Modem a nd Power
Adapter)
To install the hardware:

2 Unplug the computer (and television).
3 Connect the coaxial cable to the cable modem’s cable television (CATV)
cable connector.
4 If you plan to have the cable modem and a television connected to the
same wall outlet, you must use a cable line splitter (not included).
5 Connect one end of the included USB cable to the USB port on the cable
modem and the other end of the cable to the USB port on the computer.
CAUTION! You must use the 12VDC/1.25A power adapter that comes with
the D-Link DCM-201 cable modem. Using the wrong power adapter can
damage the cable modem.
