Product Overview
D-Link DSL-526E User Manual 5
Features
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 the 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 (Transmission Control Protocol/Internet Protocol) – The Router supports the 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 allows 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”. Create a static route 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 to a specific destination 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.
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.
Telnet Connection – 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
8 6EUserManualD-LinkDSL-52
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.
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 a standard telephone cable. Ask your service provider for more
information about the use of low pass filters with your installation.
Operating Systems
The DSL-526E 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

Installation
USB Port or Ethernet Port (NIC Adapter)
Any computer that uses the Router must be able to connect to it through either the Ethernet port or USB port on the Router. The easiest method of
installation is via the Ethernet connection, which requires your computer be equipped with an Ethernet port. 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. If your
computer does not have an Ethernet port and you do not wish to use a USB connection, you must install an Ethernet NIC adapter before you can use
the Router. If you need to 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 as 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.
If you plan to use the DSL-526E’s USB port to connect to your
computer, do not connect the USB cable to the Router until you
have finished all of the steps to install the USB driver, and your
computer has restarted.

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 your ADSL 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/PPPoA (PPPoE LLC, PPPoA LLC or PPPoA VC-Mux)
Bridge Mode (1483 Bridged IP LLC or 1483 Bridged IP VC Mux)
IPoA/MER (Static IPAddress) (Bridged IP LLC, 1483 Bridged IP VC Mux, 1483 Routed IP LLC, 1483 Routed IP VC-Mux or IPoA)
MER (Dynamic IPAddress) (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 (ADSL2+ Multi-Mode) used for the Router automatically detects all types of
ADSL, ADSL2 and ADSL2+ modulation.
Security Protocol
This is the method your ADSL 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 your ADSL service provider for the additional connections. This setting can
be changed in the WAN Settings window of the web management interface.
VCI
Most users will not be required to change this setting. The Virtual Channel Identifier (VCI) is used in conjunction with the VPI 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 your ADSL service provider for the additional connections. This setting can be changed in the WAN
Setup window of the web management interface.

Device Installation
The DSL-526E has three separate physical interfaces, anADSL (WAN), an Ethernet (LAN) interface and a USB Interface. The Router can be
connected to your PC via the USB port or the Ethernet port. 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 Ethernet LAN LED indicator 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 you have installed the device, some settings may need to be changed before the Router can
establish a connection.

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 the instructions 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 10/100 BASE-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 cabling 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 of the other MDI-X ports (1x, 2x, etc.) with a crossed cable.
Computer to Router Connection
You can either connect the Router’s Ethernet interface directly to a 10/100BASE-TX Ethernet adapter card (NIC) installed in a PC using the
Ethernet cable provided, or connect the Router to a spare USB port using the Router’s USB interface.

Configuration Configuration
This section describes how to configure your new D-Link Router using the web-based configuration utility.
