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. NA T 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 A TM (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.

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.

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.

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 your ADSL service provider uses to transport data between the Internet and your computer. Most users will use the default settings. Y ou may need to specify one of the following WAN Setting and Connection Type configurations (Connection T ype 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 IP Address) (Bridged IP LLC, 1483 Bridged IP VC Mux, 1483 Routed IP LLC, 1483 Routed IP VC-Mux or IPoA)
MER (Dynamic IP Address) (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.

Device Installation
The DSL-526E has three separate physical interfaces, an ADSL (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.
Factory Reset Button
The Router may be reset to the original factory default settings. To restore factory defaults, keep the device powered on and push a paper clip into the hole. Press down the button for 3 seconds using a ballpoint or paperclip, and then release.

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-1 1 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.

Click a hyperlinked URL in the form of hostname.dyndns.org and allow remote access to a host. Many ISPs assign public IP addresses using DHCP, so locating a specific host on the LAN using the standard DNS is difficult. For example, if you are running a public web server or VPN server on your LAN, DDNS ensures that the host can be located from the Internet even if the public IP address changes. DDNS requires that an account be set up with one of the supported DDNS service providers (DyndDNS.org or dlinkddns.com).

Network Tools
The router provides following tools: Port Mapping, IGMP Proxy, IP QoS, UPnP, SNMP, TR-069, Software Forbidden, ARP Binding, Client Limit, and Telnet.
Port Mapping
Port Mapping supports a single (LAN) port or multiple (LAN) ports to be formed as a group and mapped to a PVC (which is associated w/ a VLAN). As a result, each group of LAN ports will perform as an independent (logical) network (like a broadcast domain) among whom traffic broadcast would be prevented. This feature is useful while you would like to form multiple independent (logical) networks for multimedia applications at home. For instance, you can map PVC1 to port 1~3 to create a network (broadcast domain) for PCs for Internet, and map PVC2 to port 4 to create another network (broadcast domain) for IPTV service (devices). By using this feature (w/ multiple PVCs), data traffic and IPTV traffic would not affect each

Troubleshooting
This chapter provides solutions to problems that might occur during the installation and operation of the DSL-526E. Read the following descriptions if you are having problems. (The examples below are illustrated in Windows® XP. If you have a different operating system, the screenshots on your computer will look similar to the following examples.)
1. How to configure the DSL-526E Modem Router without the CD-ROM? 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’.
Note:
Please refer to the next section “Networking Basics” to check your PC’s IP configuration if you can’t see the login windows.
2. How to restore the Router to the factory default settings? Ensure the Router is powered on.
Press and hold the reset button on the back of the device for approximately 3 seconds. This process should take around 1 to 2 minutes.
Note:
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, and then run the Wizard.
3. What to do if the Router does not work normally?
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.
Please ensure that the settings in the Web-based configuration manager, e.g. ISP username and password, are the same as the settings
that have been provided by your ISP.

82 D-Link DSL-526E User Manual
4. Why the Internet connection cannot be established?
For ADSL ISP users, please contact your ISP to make sure the service has been enabled/connected by your ISP and that your ISP username and password are correct.
5. What to do if the Router can’t be detected by running the installation CD? Ensure the Router is powered on.
Check that all the cables are firmly connected at both ends and all LEDs are working correctly. Ensure only one network interface card on your PC is activated. Click on Start > Control Panel > Security Center to disable the firewall.
Note:
There is a potential security issue if the firewall is disabled on your PC. Please remember to turn it back on once you have finished the whole
installation
procedure. This will enable you to surf the Internet without any problems.

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 button. 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 Assigning an IP Address
If you are not using a DHCP capable gateway/router, 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 network adapter and select the Properties button.
Step 3 Highlight Internet Protocol (TCP/IP) and click on the Properties button.
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 254. Make sure that the number
you choose is not in use on the network. Set the Default Gateway to be the same as the LAN IP address of your router (192.168.1.1).
Set the Primary DNS to be 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 button twice to save your settings.
