Features
•
PPP (Point-to-Point Protocol) Security – The DSL-2640U ADSL Router supports PAP (Password Authentication Protocol) and CHAP
(Challenge Handshake Authentication Protocol) for PPP connections. The Router also supports MSCHAP.
•
DHCP Support – Dynamic Host Configuration Protocol automatically and dynamically assigns all LAN IP settings to each host on your
network. This eliminates the need to reconfigure every host whenever changes in network topology occur.
•
Network Address Translation (NAT) – For small office environments, the DSL-2640U allows multiple users on the LAN to access the
Internet concurrently through a single Internet account. This provides Internet access to everyone in the office for the price of a single user.
NAT improves network security in effect by hiding the private network behind one global and visible IP address. NAT address mapping can
also be used to link two IP domains via a LAN-to-LAN connection.
•
TCP/IP (Transfer Control Protocol/Internet Protocol) – The DSL-2640U supports TCP/IP protocol, the language used for the Internet. It is
compatible with access servers manufactured by major vendors.
•
RIP-1/RIP-2 – The DSL-2640U supports both RIP-1 and RIP-2 exchanges with other routers. Using both versions lets the Router to
communicate with all RIP enabled devices.
•
Static Routing – This allows you to select a data path to a particular network destination that will remain in the routing table and never “age
out”. If you wish to define a specific route that will always be used for data traffic from your LAN to a specific destination within your LAN (for
example to another router or a server) or outside your network (to an ISP defined default gateway for instance).
•
Default Routing – This allows you to choose a default path for incoming data packets for which the destination address is unknown. This is
particularly useful when/if the Router functions as the sole connection to the Internet.
•
ATM (Asynchronous Transfer Mode) – The DSL-2640U supports Bridged Ethernet over ATM (RFC1483), IP over ATM (RFC1577), and
PPP over ATM (RFC 2364).
•
Precise ATM Traffic Shaping – Traffic shaping is a method of controlling the flow rate of ATM data cells. This function helps to establish the
Quality of Service for ATM data transfer.
D-Link DSL-2640U User Manual
Section 1 - Product Overview
•
G.hs (Auto-handshake) – This allows the Router to automatically choose either the G.lite or G.dmt ADSL connection standards.
•
High Performance – Very high rates of data transfer are possible with the Router. Up to 8 Mbps downstream bit rate using the G.dmt
standard.
•
Full Network Management – The DSL-2640U incorporates SNMP (Simple Network Management Protocol) support for web-based
management and text-based network management via an RS-232 or Telnet connection.
•
Telnet Connection – The Telnet enables a network manager to access the Router’s management software remotely.
•
Easy Installation – The DSL-2640U uses a web-based graphical user interface program for convenient management access and easy set
up. Any common web browser software can be used to manage the Router.

Section 2 – Installation
Installation
This section will walk you through the installation process. Placement of the Router is very important. Do not place the Router in an enclosed area
such as a closet, cabinet, or in the attic or garage.
Before You Begin
Please read and make sure you understand all the prerequisites for proper installation of your new Router. Have all the necessary information and
equipment on hand before beginning the installation.
D-Link DSL-2640U User Manual
Section 2 – Installation
Installation Notes
In order to establish a connection to the Internet it will be necessary to provide information to the Router that will be stored in its memory. For some
users, only their account information (Username and Password) is required. For others, various parameters that control and define the Internet
connection will be required. You can print out the two pages below and use the tables to list this information. This way you have a hard copy of all
the information needed to setup the Router. If it is necessary to reconfigure the device, all the necessary information can be easily accessed. Be
sure to keep this information safe and private.
Low Pass Filters
Since ADSL and telephone services share the same copper wiring to carry their respective signals, a filtering mechanism may be necessary to
avoid mutual interference. A low pass filter device can be installed for each telephone that shares the line with the ADSL line. These filters are easy
to install passive devices that connect to the ADSL device and/or telephone using standard telephone cable. Ask your service provider for more
information about the use of low pass filters with your installation.
Operating Systems
The DSL-2640U uses an HTML-based web interface for setup and management. The web configuration manager may be accessed using any
operating system capable of running web browser software, including Windows 98 SE, Windows ME, Windows 2000, Windows XP, and Windows
Vista.
Web Browser
Any common web browser can be used to configure the Router using the web configuration management software. The program is designed to
work best with more recently released browsers such as Opera, Microsoft Internet Explorer® version 6.0, Netscape Navigator® version 6.2.3, or
later versions. The web browser must have JavaScript enabled. JavaScript is enabled by default on many browsers. Make sure JavaScript has not
been disabled by other software (such as virus protection or web user security packages) that may be running on your computer.
Ethernet Port (NIC Adapter)
Any computer that uses the Router must be able to connect to it through the Ethernet port on the Router. This connection is an Ethernet connection
and therefore requires that your computer be equipped with an Ethernet port as well. Most notebook computers are now sold with an Ethernet port
already installed. Likewise, most fully assembled desktop computers come with an Ethernet NIC adapter as standard equipment. If your computer
does not have an Ethernet port, you must install an Ethernet NIC adapter before you can use the Router. If you must install an adapter, follow the
installation instructions that come with the Ethernet NIC adapter.

Section 2 – Installation
Additional Software
It may be necessary to install software on your computer that enables the computer to access the Internet. Additional software must be installed if
you are using the device a simple bridge. For a bridged connection, the information needed to make and maintain the Internet connection is stored
on another computer or gateway device, not in the Router itself.
If your ADSL service is delivered through a PPPoE or PPPoA connection, the information needed to establish and maintain the Internet connection
can be stored in the Router. In this case, it is not necessary to install software on your computer. It may however be necessary to change some
settings in the device, including account information used to identify and verify the connection.
All connections to the Internet require a unique global IP address. For bridged connections, the global IP settings must reside in a TCP/IP enabled
device on the LAN side of the bridge, such as a PC, a server, a gateway device such as a router or similar firewall hardware. The IP address can be
assigned in a number of ways. Your network service provider will give you instructions about any additional connection software or NIC
configuration that may be required.

ports on the DSL-2640U to connect to other computer or Ethernet devices.
DHCP Client status
Your DSL-2640U ADSL Router is configured, by default, to be a DHCP server. This means that it can assign an IP address, subnet mask, and a
default gateway address to computers on your LAN. The default range of IP addresses the DSL-2640U will assign are from 192.168.1.2 to
192.168.1.254. Your computer (or computers) needs to be configured to obtain an IP address automatically (that is, they need to be configured as
DHCP clients.)
It is recommended that your collect and record this information here, or in some other secure place, in case you have to re-configure your ADSL
connection in the future.
Once you have the above information, you are ready to setup and configure your DSL-2640U ADSL Router.
D-Link DSL-2640U User Manual

Section 2 – Installation
Device Installation
The DSL-2640U connects two separate physical interfaces, an ADSL (WAN) and an Ethernet (LAN) interface. Place the Router in a location where
it can be connected to the various devices as well as to a power source. The Router should not be located where it will be exposed to moisture or
excessive heat. Make sure the cables and power cord are placed safely out of the way so they do not create a tripping hazard. As with any electrical
appliance, observe common sense safety procedures.
The Router can be placed on a shelf or desktop, ideally you should be able to see the LED indicators on the front if you need to view them for
troubleshooting.
Power on Router
The Router must be used with the power adapter included with the device.
1. Insert the AC Power Adapter cord into the power receptacle located on the rear panel of the Router and plug the adapter into a suitable nearby
power source.
2. Depress the Power button into the on position. You should see the Power LED indicator light up and remain lit. The Status LED should light solid
green and begin to blink after a few seconds.
3. If the Ethernet port is connected to a working device, check the LAN LED indicators to make sure the connection is valid. The Router will attempt
to establish the ADSL connection, if the ADSL line is connected and the Router is properly configured this should light up after several seconds.
If this is the first time installing the device, some settings may need to be changed before the Router can establish a connection.

Section 2 – Installation
Factory Reset Button
The Router may be reset to the original factory default settings by using a ballpoint or paperclip to gently push down the reset button in the following
sequence:
1. Press and hold the reset button while the device is powered off.
2. Turn on the power.
3. Wait for 5~8 seconds and then release the reset button.
Remember that this will wipe out any settings stored in flash memory including user account information and LAN IP settings. The device settings
will be restored to the factory default IP address 192.168.1.1 and the subnet mask is 255.255.255.0, the default management Username is “admin”
and the default Password is “admin.”
Network Connections
Connect ADSL Line
Use the ADSL cable included with the Router to connect it to a telephone wall socket or receptacle. Plug one end of the cable into the ADSL port
(RJ-11 receptacle) on the rear panel of the Router and insert the other end into the RJ-11 wall socket. If you are using a low pass filter device, follow
the instructions included with the device or given to you by your service provider. The ADSL connection represents the WAN interface, the
connection to the Internet. It is the physical link to the service provider’s network backbone and ultimately to the Internet.
Connect Router to Ethernet
The Router may be connected to a single computer or Ethernet device through the 10BASE-TX Ethernet port on the rear panel. Any connection to
an Ethernet concentrating device such as a switch or hub must operate at a speed of 10/100 Mbps only. When connecting the Router to any
Ethernet device that is capable of operating at speeds higher than 10Mbps, be sure that the device has auto-negotiation (NWay) enabled for the
connecting port. Use standard twisted-pair cable with RJ-45 connectors. The RJ-45 port on the Router is a crossed port (MDI-X). Follow standard
Ethernet guidelines when deciding what type of cable to use to make this connection. When connecting the Router directly to a PC or server use a
normal straight-through cable. You should use a crossed cable when connecting the Router to a normal (MDI-X) port on a switch or hub. Use a
normal straight-through cable when connecting it to an uplink (MDI-II) port on a hub or switch. The rules governing Ethernet cable lengths apply to
the LAN to Router connection. Be sure that the cable connecting the LAN to the Router does not exceed 100 meters.
Hub or Switch to Router Connection
Connect the Router to an uplink port (MDI-II) on an Ethernet hub or switch with a straight-through cable. If you wish to reserve the uplink port on the
switch or hub for another device, connect to any on the other MDI-X ports (1x, 2x, etc.) with a crossed cable.
Computer to Router Connection
You can connect the Router directly to a 10/100BASE-TX Ethernet adapter card (NIC) installed on a PC using the Ethernet cable provided.

How do I reset my Router to the factory default settings?
•
•
•
Note:
3.
Connect your PC to the Router using an Ethernet cable.
Open a web browser and enter the address http://192.168.1.1
The default username is ‘admin’ and the default password is ‘admin’.
If you have changed the password and cannot remember it, you will need to reset the Router to the factory default setting (see question 2),
which will set the password back to ‘admin’.
Ensure the Router is powered on.
Press and hold the reset button on the back of the device for approximately 5 to 8 seconds.
This process should take around 30~60 seconds.
Resetting the Router to the factory default settings will erase the current configuration settings. To reconfigure your settings, login to the Router as
outlined in question 1, then run the Quick Setup wizard.
What can I do if my Router is not working correctly?
There are a few quick steps you can take to try and resolve any issues:
• Follow the directions in Question 2 to reset the Router.
• Check that all the cables are firmly connected at both ends.
• Check the LEDs on the front of the Router. The Power indicator should be on, the Status indicator should flash, and the DSL and LAN
indicators should be on as well.

Check Your IP Address
After you install your new D-Link adapter, by default, the TCP/IP settings should be set to obtain an IP address from a DHCP server (i.e. wireless
router) automatically. To verify your IP address, please follow the steps below.
Click on Start > Run. In the run box type cmd and click on the OK.
At the prompt, type ipconfig and press Enter.
This will display the IP address, subnet mask, and the default
gateway of your adapter.
If the address is 0.0.0.0, check your adapter installation, security
settings, and the settings on your router. Some firewall software
programs may block a DHCP request on newly installed adapters.
If you are connecting to a wireless network at a hotspot (e.g. hotel,
coffee shop, airport), please contact an employee or administrator
to verify their wireless network settings.

Statically Assign an IP Address
If your DHCP is disabled, or you need to assign a static IP address, please follow the steps below:
Step 1
Windows® XP - Click on Start > Control Panel > Network Connections.
Windows® 2000 - From the desktop, right-click on the My Network Places > Properties.
Step 2
Right-click on the Local Area Connection which represents your D-Link network adapter and select Properties.
Step 3
Highlight Internet Protocol (TCP/IP) and click on the Properties.
Step 4
Click on the Use the following IP address and enter an IP address that is on the same subnet as
your network or the LAN IP address on your router.
Example: If the router’s LAN IP address is 192.168.1.1, make your IP address 192.168.1.X where X
is a number between 2 and 99. Make sure that the number you choose is not in use on the network.
Set Default Gateway the same as the LAN IP address of your router (192.168.1.1).
Set Primary DNS the same as the LAN IP address of your router (192.168.1.1). The Secondary
DNS is not needed or you may enter a DNS server from your ISP.
Step 5
Click on the OK twice to save your settings.
