Features
• PPP (Point-to-Point Protocol) Security – The DSL-2600U 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-2600U 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-2600U 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-2600U 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.
• 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.
• Full Network Management – The DSL-2600U incorporates SNMP (Simple Network Management Protocol) support for web-based management and text-based
network management.
• Easy Installation – The DSL-2600U 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
D-Link DSL-2640B User Manual 5
Installation
This section will walk you through the installation process. Placement of the Wireless ADSL Router is very important. Do not place the Router in an enclosed area such
as a closet, cabinet, or in the attic or garage. Place the Wireless ADSL Router in a location where it can be easily connected to Ethernet devices, the telephone line as
well as to a power source.
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-2600U 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.
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.
Wireless LAN
Computers using the Wireless network can access the Internet or use the embedded 802.1g wireless access point. Wireless workstations must have an 802.1g or
802.1b wireless network card installed to use the Wireless ADSL Router. In addition the workstations must be configured to operate on the same channel and SSID as
the Wireless ADSL Router. If wireless security is used, the wireless workstations must be properly configured for the security settings used.
Installation
D-Link DSL-2640B User Manual 7
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.
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, PPPoE VC-Mux, PPPoA LLC or PPPoA VC-Mux)
• Dynamic IP Address (1483 Bridged IP LLC, 1483 Bridged IP VC-Mux)
• Static IP Address (1483 Bridged IP LLC, 1483 Bridged IP VC-Mux, 1483 Routed IP LLC (IPoA) or 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 (Auto Synch-Up) 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) 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 Settings window of the web management interface.

If your computer has an Ethernet NIC, you can connect the DSL-2600U to this Ethernet port using an Ethernet cable. You can also use the Ethernet ports on the
DSL-2600U to connect to other computer or Ethernet devices.
DHCP Client status
Your DSL-2600U 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-2600U will assign are from 10.1.1.5 to 10.1.1.254. 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 you 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-2600U ADSL Router.

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 10/100BASE-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.
Wireless Connection to Router
The Router’s embedded 802.11g wireless access point should be configured to suit the local wireless network. All 802.11g or 802.11b devices that associate with the
Router’s wireless access point must have the same SSID and channel. If wireless security is used, the wireless clients must be configured with the correct security
information to use the Router. More information on configuring the wireless settings is found later in this manual.

D-Link DSL-2600U User Manual 11
Introduction to Web Configuration
The first time you setup the Router. It is recommended that you configure the WAN connection using a single computer, to ensure that both the computer and the Router are
not connected to the LAN. Once the WAN connection operates properly, you may continue to make changes to Router configuration, including IP settings and DHCP setup.
This chapter is concerned with using your computer to configure the WAN connection. The following chapter describes the various menus used to configure and monitor the
Router, including how to change IP settings and DHCP server setup.
Preparation Before Login
Before accessing the Modem, ensure the communication between PC and Modem is normal. Check the communication as follows.
= Configure the IP address of the PC as 10.1.1.X (2~254), net mask as
255.0.0.0, gateway address as 10.1.1.1 (for customized version, configure
them according to the actual version).
= Enter arp -a in the DOS window to check whether the PC can read the MAC
address of the Modem.
= Ping the management IP address (10.1.1.1 by default) of the Modem.
If the PC can read the MAC address of the Modem and can ping through the
management IP address of the Modem, that means the communication of
the PC and the Modem is normal.

modification, such as adding a static route, takes effect at once, and does not require modem reboot.
Web Configuration
D-Link DSL-2600U User Manual 14
Quick Setup
The Quick Setup page mainly includes the following three functions:
= WAN interface setup
= LAN interface setup
= Wireless interface setup
Quick setup enables fast and accurate configuration of your Internet connection and other important parameters. The following sections describe these various
configuration parameters. Whether you configure these parameters or use the default ones, click Next to enable your Internet connection.
When subscribing to a broadband service, you should be aware of the method by which you are connected to the Internet. Your physical WAN device can be Ethernet,
DSL, or both. Technical information regarding the properties of your Internet connection should be provided by your Internet service provider (ISP). For example, your ISP
should inform you whether you are connected to the Internet by using a static or dynamic IP address, or the protocols, such as PPPOA or PPPoE, which you use to
communicate over the Internet.
WAN Interface Setup
During WAN interface setup, you can set up a PVC and its properties:
= VPI
= VCI
= QoS
= Internet connection type
= Encapsulation type
= IGMP service
= NAT
Setting Up VPI/VCI and QoS
After logging in to the DSL router, if no PVC is configured previously and no default settings
exist, the Quick Setup webpage appears, which contains some basic configuration that is
needed by ATM PVC. The following introduction guides you through the necessary steps to
configure your DSL Router.
Web Configuration
D-Link DSL-2600U User Manual 15
According to your ISP instructions, specify the following parameters:
= VPI (Virtual Path Identifier)
Virtual path between two points in an ATM network. The valid value range is from 0
to 255.
= VCI (Virtual Channel Identifier)
Virtual channel between two points in an ATM network. The valid value range is from
32 to 65535 (1 to 31 are reserved for known protocols).
= Enable Quality Of Service
Enabling QoS for a PVC improves performance for selected classes of applications.
However, since QoS also consumes system resources, the number of PVCs is
reduced consequently. Use Advanced Setup/Quality of Service to assign priorities
for the applications.
For example, PVC 0/35 is to be modified and the default values of QoS remain. In actual
applications, you can modify them depending on your ISP instructions.
Selecting Internet Connection Type and Encapsulation Type
You can select your connection type from the following list. Each connect type corresponds
to several encapsulation types:
= PPP over ATM (PPPoA)
PPPoA Encapsulation Mode: VC/MUX, LLC/ENCAPSULATION
= PPP over Ethernet (PPPoE)
PPPoE Encapsulation Mode: LLC/SNAP-BRIDGING, VC/MUX
= MAC Encapsulation Routing (MER)
MER Encapsulation Mode: LLC/SNAP-BRIDGING, VC/MUX
= IP over ATM (IPoA)
IPoA Encapsulation Mode: LLC/SNAP-ROUTING, VC/MUX
= Bridging
Bridging Encapsulation Mode: LLC/SNAP-BRIDGING, VC/MUX
For example, change the connection type of PVC 0/35 to Bridging. Select Bridging, and set
Encapsulation Mode to LLC/SNAP-BRIDGING (depending on the uplink equipment).

Overview
Setting up the NAT Function
= The DSL router is equipped with the network address translation (NAT) function. With address mapping, several users in the local network can access the Internet via
one or more public IP addresses. All the local IP addresses are assigned to the public IP address of the router by default.
= One of the characteristics of NAT is that data from the Internet is not allowed into the local network unless it is explicitly requested by one of the PCs in the network.
Most Internet applications can run behind the NAT firewall without any problems. For example, if you request Internet pages or send and receive e-mails, the request
for data from the Internet comes from a PC in the local network, and so the router allows the data to pass through. The router opens one specific port for the
Web Configuration
D-Link DSL-2600U User Manual 33
application. A port in this context is an internal PC address, via which the data is exchanged between the Internet and a client on a PC in the local network.
Communicating via a port is subject to the rules of a particular protocol (TCP or UDP).
= If an external application tries to send a call to a PC in the local network, the router blocks it. There is no open port via which the data could enter the local network.
Some applications, such as games on the Internet, require several links (that is. several ports), so that players can communicate with each other. In addition, these
applications must also be permitted to send requests from other users on the Internet to users in the local network. These applications cannot run if NAT is activated.
= Using port forwarding (the forwarding of requests to particular ports), the router is forced to send requests from the Internet for a certain service, for example, a game,
to the appropriate port(s) on the PC on which the game is running. Port triggering is a special variant of port forwarding. Unlike port forwarding, the DSL router
forwards the data from the port block to the PC which has previously sent data to the Internet via a certain port (trigger port). This means that approval for the data
transfer is not tied to one specific PC in the network, but rather to the port numbers of the required Internet service. Where configuration is concerned, you must
define a so-called trigger port for the application and also the protocol (TCP or UDP) that this port uses. You then assign the public ports that are to be opened for the
application to this trigger port. The router checks all outgoing data for the port number and protocol. If it identifies a match of port and protocol for a defined trigger port,
then it opens the assigned public ports and notes the IP address of the PC that sent the data. If data comes back from the Internet via one of these public ports, the
router allows it to pass through and directs it to the appropriate PC. A trigger event always comes from a PC within the local network. If a trigger port is addressed
from outside, the router simply ignores it.
Note:
= An application that is configured for port triggering can only be run by one user in the local network at a time.
= After public ports are opened, they can be used by unauthorized persons to gain access to a PC in the local network.
= When the DSL router is supplied, the NAT function is activated. For example, all IP addresses of PCs in the local network are converted to the public IP address of the
router when accessing the Internet. You can use NAT settings to configure the DSL router to carry out the following tasks.
= For functions described as follows, IP addresses of the PCs must remain unchanged. If the IP addresses of the PCs are assigned via the DHCP server of the DSL
router, you must disable DHCP server as the settings in the local network menu entry for the lease time or assign static IP addresses for the PCs.
You can enable or disenable the NAT function. By default, the NAT function is enabled.
NAT-Virtual Server Setup
By default, DSL router blocks all external users from connecting to or communicating with your network. Therefore, the system is safe from hackers who may try to intrude
into the network and damage it.
However, you may want to expose your network to the Internet in limited and controlled ways in order to enable some applications to work from the LAN (for example,
game, voice, and chat applications) and to enable Internet access to servers in the home network. The port forwarding feature supports both functionalities. This topic is
also referred as Local Servers.
The port forwarding page is used to define applications that require special handling by DSL router. All you need to do is to select the application protocol and the local IP
address of the computer that is using or providing the service. If required, you may add new protocols in addition to the most common ones provided by DSL router.
For example, if you wanted to use a file transfer protocol (FTP) application on one of your PCs, you would simply select FTP from the list and enter the local IP address or
host name of the designated computer. All FTP-related data arriving at DSL router from the Internet henceforth is forwarded to the specific computer.
Similarly, you can grant Internet users access to servers inside your home network, by identifying each service and the PC that provide it. This is useful, for example, if you
want to host a Web server inside your home network.
When an Internet user points his/her browser to DSL router external IP address, the gateway forwards the incoming HTTP request to your Web server. With one external
IP address (DSL router main IP address), different applications can be assigned to your LAN computers, however each type of application is limited to use one computer.
Web Configuration
D-Link DSL-2600U User Manual 34
For example, you can define that FTP uses address X to reach computer A and Telnet also uses address X to reach computer A. But attempting to define FTP to use
address X to reach both computer A and B fails. DSL router, therefore, provides the ability to add additional public IP addresses to port forwarding rules, which you must
obtain from your ISP, and enter into the IP addresses pool. Then, you can define FTP to use address X to reach computer A and address Y to reach computer B.
Additionally, port forwarding enables you to redirect traffic to a different port instead of the one to which it was designated. For example, if you have a Web server running
on your PC on port 8080 and you want to grant access to this server to any one who accesses DSL router via HTTP.
To accomplish this, do as follows:
Step 1 Define a port forwarding rule for the HTTP service, with the PC IP or host name.
Step 2 Specify 8080 in the Forward to Port field.
All incoming HTTP traffic is forwarded to the PC running the Web server on port 8080. When setting a port forwarding service, ensure that the port is not used by another
application, which may stop functioning. A common example is when using SIP signaling in Voice over IP, the port used by the gateway VoIP application (5060) is the same
port, on which port forwarding is set for LAN SIP agents.
Note: Some applications, such as FTP, TFTP, PPTP and H323, require the support of special specific application level gateway (ALG) modules in order to work inside the
home network. Data packets associated with these applications contain information that allows them to be routed correctly. An ALG is needed to handle these
packets and ensure that they reach their intended destinations. DSL router is equipped with a robust list of ALG modules in order to enable maximum functionality in
the home network. The ALG is automatically assigned based on the destination port.
Virtual servers are configured for this purpose.
Adding Port Forwarding
Step 1 To set up virtual servers for a service, select Advanced Setup > NAT > Virtual
Servers, and click Add.
Web Configuration
D-Link DSL-2600U User Manual 35
Step 2 Select a service or enter a custom server.
Step 3 Set Server IP Address.
Step 4 Enter the server IP address of the computer that provides the service (the server
in the local host field). Note that unless an additional external IP address is
added, only one LAN computer can be assigned to provide a specific service or
application.
Step 5 Set External Port Start and External Port End.
Step 6 Select Protocol.
Step 7 Set Internal Port Start and Internal Port End.
Step 8 Enter Remote IP.
Step 9 Click Save/apply to apply the settings.
If the application you require is not in the list, manually enter the information.
Select the protocol for the service you are providing from the Protocol drop-down list.
Under External Port, enter the port number of the service you are providing. In the
Internal Port field, enter the internal port number, to which service requests are to be
forwarded. In the Local IP Address field, enter the IP address of the PC that provides the
service.
Example
The Web server is configured to react to requests on port 8080. However, the requests from websites enter the Web server via port 80 (standard value). If you add the PC
to the forwarding table and define port 80 as the public port and port 8080 as an internal port, all requests from the Internet are diverted to the service with port 80 on the
Web server of the PC you have defined with port 8080.
Deleting Port Forwarding
Step 1 Select the Remove check box.
Step 2 Click Remove to apply the settings.
Port Triggering
If you configure port triggering for a certain application, you need to determine a so-called trigger port and the protocol (TCP or UDP) that this port uses. You then assign
the public ports that are to be opened for the application to this trigger port. You can select known Internet services or manually assign ports or port blocks.

= Users who want to use a special-purpose Internet service, such as an on-line game or video conferencing program, that is not presented in the port forwarding list
and for which no port range information is available.
= Users who are not concerned with security and wish to expose one computer to all services without restriction.
Note: A DMZ host is not protected by the firewall and may be vulnerable to attack. This may also put other computers in the home network at risk. Hence, when
designating a DMZ host, you must consider the security implications and protect it if necessary.
Web Configuration
D-Link DSL-2600U User Manual 37
You can set up a client in your local network as a so-called DMZ host. Your device then forwards all incoming data traffic from the Internet to this client. You can, for
example, operate your own Web server on one of the clients in your local network and make it accessible to Internet users. As the exposed host, the local client is directly
visible to the Internet and therefore particularly vulnerable to attacks (for example, hacker attacks). Enable this function only when necessary (for example, to operate a
Web server) and when other functions (for example, port forwarding) are inadequate. In this case, you should take appropriate measures for the clients concerned.
Note: Only one PC per public IP address can be set up as an exposed host.

Quality of Service
Many communication and multimedia applications require large, high-speed bandwidths to transfer data between the local network and the internet. However, for many
applications there is often only one internet connection available with limited capacity. QoS divides this capacity between the different applications and provides undelayed,
continuous data transfer in situation where data packets with higher priority are given preference.
Click Quality of Service and the following page appears. Under Quality of Service, there are two network share modes: Queue Config and QoS Classification.
Network QoS is an industry-wide set of standards and mechanisms for ensuring high-quality performance for critical applications. By using QoS mechanisms, network
administrators can use existing resources efficiently and ensure the required level of service without reactively expanding or over-provisioning their networks.
Traditionally, the concept of quality in networks meant that all network traffic was treated equally. The result was that all network traffic received the network’s best effort,
with no guarantees for reliability, delay, variation in delay, or other performance characteristics. With best-effort delivery service, however, a single bandwidth-intensive
application can result in poor or unacceptable performance for all applications. The QoS concept of quality is one in which the requirements of some applications and
users are more critical than others, which means that some traffic needs preferential treatment.

queue. A maximum of 24 entries can be configured.
QoS Queue Configuration can allocate four queues. Each of the queues can be
configured for a precedence value (Lower integer values for precedence imply higher
priority for this queue relative to others). The queue entry configured is used by the
classifier to place ingress packets appropriately.
Note: Lower integer values for precedence imply higher priority for this queue relative to
others.
For example, add a QoS queue entry and allocate it to a specific network interface (PVC
0/0/35). Set integer values for queue precedence to 1.
Web Configuration

Step 1 Click Add, and the following page appears.
= Policy Select: you can select Strict Priority Policy or WRR Policy.
= Queue Configuration Status: set to enable or disable a QoS queue.
= Queue: select a specific network interface. When you have already selected a
network interface, the specific network interface selected automatically allocates to
the queue.
= Queue Precedence: select an integer value for queue precedence. After you select
an integer value, the queue entry appropriately places to ingress packets. Lower
integer values for precedence imply higher priority for this queue relative to others.
Step 2 Add a QoS queue entry and assign it to a specific network interface (PVC
0/0/35), and set integer values for queue precedence to 1. See the following
figure:

Step 3 After proper modifications, click Save/Apply and the following page appears.
This configuration takes effective at once.
To delete a certain queue, disable it, select it, and then click Remove.
After the queue is configured, you can create several traffic class rules to classify the
upstream traffic.
WRR (Weighted Round Robin): this is another QoS method. If you want to set WRR, you
must disable the Strict-Priority Queue (PQ). The WRR is mutex to PQ. Only one QoS
method can exist at the same time. Select WRR in QoS Queue Configuration page. The
following interface appears.
For example, add a QoS queue entry and allocate it to a specific network interface (PVC
0/2/35). Set queue precedence to 2 and weight value to 30%.
Web Configuration
D-Link DSL-2600U User Manual 46
After proper modifications, click Save/Apply and the following page appears.
The weighted round robin (WRR) queue schedule divides each port into several output queues. Queues are scheduled in turn to ensure that each queue obtains a certain
service time. WRR configures a weighted value (w3, w2, w1 and w0) for each queue. The weighted value represents the proportion of the obtained resources. For
example, the weighted value of WRR queue schedule algorithm of a 100M port is configured as 50, 30, 10 and 10 (corresponding to w3, w2, w1 and w0), so that the queue
with minimum priority obtains a bandwidth of at least 10Mbps, which avoids the disadvantage that a message in queue with low priority during PQ schedule may not obtain
service for a long time. WRR queue still has another advantage. Although the schedule of these queues are conducted in turn, each queue is not assigned with a fixed
service time slice-if a certain queue is null, it is immediately changed to the next queue. In this way, the bandwidth resources can be fully utilized.
QoS-QoS Classification
Some applications require specific bandwidth to ensure its data be forwarded in time. QoS
classification can creates traffic class rule to classify the upstream traffic. Assign queue
which defines the precedence and the interface and optionally overwrite the IP header
DSCP byte. After QoS classification, QoS divides capacity between different applications
and provides undelayed, continuous data transfer where data packet with higher priority is
given preference. The follow figure shows QoS classification.

QoS-DSCP Setting
In order to understand what is differentiated services code point (DSCP), you should be familiar with the differentiated services model (Diffserv).
Diffserv is a class of service (CoS) model that enhances best-effort Internet services via differentiating traffic by users, service requirements and other criteria. Packets are
specifically marked, allowing network nodes to provide different levels of service,
via priority queuing or bandwidth allocation, or by choosing dedicated routes for specific traffic flows.
As displayed in following diagram, the IPV4 packet has a TOS filed. Diffserv defines TOS field in IP packet headers referred to as DSCP. Hosts or routes that pass traffic to
a Diffserv-enabled network typically mark each transmitted packet with an appropriate DSCP. The DSCP markings are used by Diffserv network routers to appropriately
classify packets and to apply particular queue handing or scheduling behavior.

Wireless
This section introduces the wireless LAN and some basic configurations. Wireless LAN can be as simple as two computers with wireless LAN cards communicating in a
peer-to-peer network or as complex as a number of computers with wireless LAN cards communicating through access points (AP) that bridge network traffic to the wired
LAN.
The Modem Wi-Fi® certified IEEE 802.11g compliant wireless access point allows multiple computers to connect wirelessly to your local network over the Modem Wireless
LAN environment. The Modem is backward compatible with IEEE 802.11b, which means 802.11b and 802.11g devices can coexist in the same wireless network. The
Wireless Distribution System (WDS) on your Modem allows you to extend the range of your wireless network. To be able to use WDS, you will need to introduce an
additional WDS-enabled access point into your wireless network. To be able to connect the computers, make sure that a wireless client adapter (WLAN client) is installed
on each computer you want to connect via the WLAN.
Wireless LAN Basics
Some basic understanding of 802.11b/g wireless technology and terminology is useful when you are setting up the Router or any wireless access point. If you are not
familiar with wireless networks please take a few minutes to learn the basics.
Wireless client requirements
All wireless client adapters compliant to 802.11g and/or 802.11b can communicate with the Modem (W) LAN environment. However, be aware that only 802.11g compliant
wireless clients are able to gain full profit of the 54 Mb/s (Max) bandwidth delivered by the Modem. It is highly recommended to use only wireless client adapters that are
Wi-Fi™ certified to ensure smooth interoperability with the Modem’s WLAN.
Radio Transmission
Wireless LAN or WLAN devices use electromagnetic waves within a broad, unlicensed range of the radio spectrum to transmit and receive radio signals. When a wireless
access point is present, it becomes a base station for the WLAN nodes in its broadcast range. WLAN nodes transmit digital data using FM (frequency modulation) radio
Web Configuration
D-Link DSL-2600U User Manual 61
signals. WLAN devices generate a carrier wave and modulate this signal using various techniques. Digital data is superimposed onto the carrier signal. This radio signal
carries data to WLAN devices within range of the transmitting device. The antennae of WLAN devices listen for and receive the signal. The signal is demodulated and the
transmitted data extracted. The transmission method used by the access point is called Direct Sequence Spread Spectrum (DSSS) and operates in a range of the radio
spectrum between 2.4GHz and 2.5GHz for transmission. See the expert technical specifications for more details on wireless operation.
Antennas
Direct the external antenna to allow optimization of the wireless link. If for example the antenna is erect, wireless links in the horizontal plane are favored. Please note that
the antenna characteristics are influenced by the environment, that is, by reflections of the radio signal against walls or ceilings. It is advisable to use the received signal
strength as indicated by the wireless client manager to optimize the antenna position for the link to a given client. Concrete walls weaken the radio signal and thus affect
the connection.
Range
Range should not be a problem in most homes or small offices. If you experience low or no signal strength in some areas, consider positioning the Router in a location
between the WLAN devices that maintains a roughly equal straight-line distance to all devices that need to access the Router through the wireless interface. Adding more
802.11g access points to rooms where the signal is weak can improve signal strength. Read the section about placement of the Router titled Location in the next chapter,
Hardware Installation, for more information.
SSID
Wireless networks use an SSID (Service Set Identifier) to allow wireless devices to roam within the range of the network. Wireless devices that wish to communicate with
each other must use the same SSID. Several access points can be set up using the same SSID so that wireless stations can move from one location to another without
losing connection to the wireless network. The Modem operates in Infrastructure mode. It controls network access on the wireless interface in its broadcast area. It will
allow access to the wireless network to devices using the correct SSID after a negotiation process takes place. By default the Modem broadcasts its SSID so that any
wireless station in range can learn the SSID and ask permission to associate with it. Many wireless adapters are able to survey or scan the wireless environment for
access points. An access point in Infrastructure mode allows wireless devices to survey that network and select an access point with which to associate. You may disable
SSID broadcasting the wireless menu of web management.
Radio channels
The 802.11g standard allows several WLAN networks using different radio channels to be co-located. The Modem supports multiple radio channels and is able to select
the best radio channel at each startup. You can choose to set the channels automatically or manually.
The different channels overlap. To avoid interference with another access point, make sure that the separation (in terms of frequency) is as high as possible. It is
recommended to keep at least 3 channels between 2 different access points.
The Modem supports all channels allowed for wireless networking. However, depending on local regulations, the number of channels actually allowed to be used may be
additionally restricted, as shown in the table below.
Regulatory Domain Allowed Radio Channels
China 1 to 13
Europe 1 to 13
Israel 5 to 8
Japan 1 to 14
Jordan 10 to 13
Thailand 1 to 14
USA / Canada 1 to 11

D-Link DSL-2600U User Manual 62
Wireless Security
Various security options are available on the Modem including open or WEP, 802.1x, WPA, WPA-PSK, WPA2 and WPA2-PSK. Authentication may use an open system or
a shared key. For details on these methods and how to use them, please read the wireless LAN configuration information in Section 3.5.3 (Wireless Security
Configuration).
About 802.11g Wireless
802.11b is an IEEE standard, operating at 2,4 GHz at a speed of up to 11 Mb/s. 802.11g, a newer IEEE standard also operating at 2,4 GHz, gives you up to 54 Mb/s speed,
more security and better performance.
Today's 11-megabits-per-second 802.11b wireless networks are fine for broadband Internet access (which typically tops out at about 1 mbps) but rather slow for large
internal file transfers or streaming video. However, 54-mbps, corporate-oriented 802.11a is expensive and because its radio uses the 5-GHz band and 802.11b uses the
2.4 GHz band, upgrading to an 802.11a network means either scrapping 802.11b gear or buying even-pricier hardware that can support both standards.
But 802.11g promises the same speed as 802.11a and the ability to coexist with 802.11b equipment on one network, since it too uses the 2.4-GHz band. 802.11g is an
extension to 802.11b, the basis of many wireless LANs in existence today. 802.11g will broaden 802.11b's data rates to 54 Mbps within the 2.4 GHz band using OFDM
(orthogonal frequency division multiplexing) technology. Because of backward compatibility, an 802.11b radio card will interface directly with an 802.11g access point (and
vice versa) at 11 Mbps or lower depending on range. You should be able to upgrade the newer 802.11b access points to be 802.11g compliant via relatively easy firmware
upgrades.
Similar to 802.11b, 802.11g operates in the 2.4GHz band, and the transmitted signal uses approximately 30MHz, which is one third of the band. This limits the number of
non-overlapping 802.11g access points to three, which is the same as 802.11b.
Note: Maximum wireless signal rate based on IEEE Standard 802.11g specifications is 54 Mbps. But actual data throughput varies depending on network conditions and
environmental factors, including volume of network traffic, building materials and construction, and network overhead will cause lower actual data throughput rate.
Access Point and Wireless Fidel
The Wi-Fi certification ensures that your Modem will interoperate with any Wi-Fi certified 802.11g and 802.11b compliant wireless device.
The Modem Wireless LAN Access Point (AP) behaves as a networking hub allowing to wirelessly interconnect several devices to the local (W) LAN and to provide access
to the Internet.

= RTS Threshold: This value should remain at its default setting of 2347.Should you encounter inconsistent data flow, only minor reductions are recommended. Should
you encounter inconsistent data flow, only minor reduction of the default value, 2347, is recommended. If a network packet is smaller than the preset RTS threshold
size, the RTS/CTS mechanism will not be enabled. The Router sends Request to Send (RTS) frames to a particular receiving station and negotiates the sending of a

data frame. After receiving an RTS, the wireless station responds with a Clear to Send (CTS) frame to acknowledge the right to begin transmission. The RTS
Threshold value should remain at its default value of 2347.
= DTIM Interval: (Delivery Traffic Indication Message) Enter a value between 1 and 255 for the Delivery Traffic Indication Message (DTIM.) A DTIM is a countdown
informing clients of the next window for listening to broadcast and multicast messages.
= Beacon Interval: Beacon is a packet of information that is sent from a connected device to all other devices where it announces its availability and readiness. A
beacon interval is a period of time (sent with the beacon) before sending the beacon again. The beacon interval may be adjusted in milliseconds (ms). Default (100)
is recommended.
= XPress™ Technology: Select Enable or Disable. This is a special accelerating technology for IEEE802.11g. The defaule is Disabled.
= 54g™ Mode: Compatible with IEEE 802.11b, IEEE 802.11g. Select a Standards from the drop-down list box. Its default setting is 54g Auto. The drop-down list box
includes below mode.
= 54g™ Protection: The 802.11g standards provide a protection method so 802.11g and 802.11b devices can co-exist in the same network without “speaking” at the
same time. Do not disable 54g Protection if there is a possibility that a 802.11b device may need to use your wireless network. In Auto Mode, the wireless device will
use RTS/CTS to improve 802.11g performance in mixed 802.11g/802.11b networks. Turn protection off to maximize 802.11g throughput under most conditions.
= Preamble Type: Preambles are a sequence of binary bits that help the receivers synchronize and ready for receipt of a data transmission. Some older wireless
systems like 802.11b implementation use shorter preambles. If you are having difficulty connecting to an older 802.11b device, try using a short preamble. You can
select short preamble only if the 54g mode is set to 802.11b.
= Transmit Power: Adjust the transmission range here. This tool can be helpful for security purposes if you wish to limit the transmission range.

Troubleshooting
This chapter provides solutions to problems that might occur during the installation and operation of the DSL-2600U. 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 do I configure my DSL-2600U Router without the CD-ROM?
= Connect your PC to the Router using an Ethernet cable.
= Open a web browser and enter the address http://10.1.1.1 .
= The default username is ‘admin’ and the default password is ‘admin’.

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 Start > Run. In the run box type “cmd” and click 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
D-Link DSL-2600U User Manual 84
Statically Assign 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 Start > Control Panel > Network Connections.
Windows® 2000 - From the desktop, right-click My Network Places > Properties.
Step 2
Right-click the Local Area Connection that represents your D-Link network adapter and select Properties.
Step 3
Highlight Internet Protocol (TCP/IP) and click 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 10.1.1.1, make your
IP address 10.1.1.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 Default Gateway the same as the LAN IP
address of your router (10.1.1.1).
Set Primary DNS the same as the LAN IP address of your
router (10.1.1.1). 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.
