Features and Benefits
PPP (Point-to-Point Protocol) Security – The 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 Router 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 Router 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 Router 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 Router 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.
High Performance – Very high rates of data transfer are possible with the Router. Up to 24 Mbps downstream bit rate using ADSL 2+ standard.
Full Network Management – The Router 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 Router 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.

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.
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-2760U 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.

D-Link DSL-2760U USER’S MANUAL
10
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.
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 ADSLservice is delivered through a PPPoE or PPPoAconnection, 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.

Information you will need from your ADSL service provider
Username
This is the Username used to log on to your ADSL service provider’s network. Your ADSL service provider uses this to identify your account.
Password
This is the Password used, in conjunction with the Username above, to log on to your ADSL service provider’s network. This is used to verify the identity of your
account.
WAN Setting / Connection Type
These settings describe the method yourADSL service provider uses to transport data between the Internet and your computer. Most users will use the default
settings. You may need to specify one of the following WAN Setting and Connection Type configurations (Connection Type settings listed in parenthesis):
PPPoE/PPoA (PPPoE LLC, PPPoE VC-Mux, PPPoA LLC, or PPPoA VC-Mux)
Dynamic IP Address (1483 Bridged IP LLC or 1483 Bridged IP VC-Mux)
Static IPAddress (Bridged IP LLC, 1483 Bridged IP VC Mux, 1483 Routed IP LLC, 1483 Routed IP VC-Mux)
Bridge Mode (1483 Bridged IP LLC or 1483 Bridged IP VC Mux)
Modulation Type
ADSL uses various standardized modulation techniques to transmit data over the allotted signal frequencies. Some users may need to change the type of
modulation used for their service. The default DSL modulation (Autosense) used for the Router automatically detects all types of ADSL, ADSL2, and ADSL2+
modulation.
Security Protocol
This is the method yourADSL service provider will use to verify your Username and Password when you log on to their network. Your Router supports the PAP
and CHAP protocols.
VPI
Most users will not be required to change this setting. The Virtual Path Identifier (VPI) is used in conjunction with the Virtual Channel Identifier (VCI) to identify the
data path between your ADSL service provider’s network and your computer. If you are setting up the Router for multiple virtual connections, you will need to
configure the VPI and VCI as instructed by yourADSL service provider for the additional connections. This setting can be changed in the WAN Settings window
of the web management interface.

DSL-2760U to connect to other computer or Ethernet devices.
DHCP Client status
Your DSL-2760U 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-2760U 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 ADSLconnection in the
future.
Once you have the above information, you are ready to setup and configure your DSL-2760U.

D-Link DSL-2760U USER’S MANUAL

Device Installation
The DSL-2760U connects two separate physical interfaces, anADSL (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.
3. If the Ethernet port is connected to a working device, check the Ethernet Link/Act LED indicators to make sure the connection is valid. The Router will
attempt to establish theADSL connection, if theADSL 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.
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. Ensure the Router is powered on.
2. Press and hold the reset button on the back of the device for approximately 6 to 10 seconds.
3. This process should take around 1 to 2 minutes.
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.
