Installing the Router
Connect the ADSL and Telephone Lines
• Connect an RJ-11 cable between the wall phone jack and the line-end of the splitter (see diagram
below).
• Attach another RJ-11 phone cable to the router-end of the splitter and the ADSL port on the rear panel
of the router.
• The phone-end of the splitter will be connected to the telephone using a third RJ-11 phone cable.
NOTE: See connections on the installation diagram.
Connect the PC to the Router
• To use the Ethernet connection, connect the Ethernet cable from the computer directly to the router.
Connect one end of the Ethernet cable to the port labeled LAN on the back of the router and attach the
other end to the Ethernet port of your computer.
• If your LAN has more than one computer, you can attach one end of an Ethernet cable to a hub or a
switch and the other to the Ethernet port (labeled LAN) on the router. Note that either a crossover or
straight-through Ethernet cable can be used.The router automatically recognizes the type of connection
that is required.

Rate):
UBR service is suitable for applications that can
tolerate variable delays and some cell losses. The
Peak Cell Rate is a determining factor in how often
cells are sent in an effort to minimize lag or jitter
caused by traffic inconsistencies.
CBR (Constant Bit Rate): Used by applications that require a fixed data rate
that is continuously available during the connection
time. It is commonly used for uncompressed audio
and video information such as videoconferencing,
interactive audio (telephony), audio / video distribution
(e.g.television, distance learning, and pay-per-view),
and audio / video retrieval (e.g.video-on-demand and
audio library).

Troubleshooting
This chapter provides solutions to problems that can occur during the installation and operation of the DSL-ꢀ540B.
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. Why can’t I access the web-based configuration utility?
When entering the IP address of the D-Link router (19ꢀ.168.1.1 for example), you are not connecting to a website on
the Internet or have to be connected to the Internet.The device has the utility built-in to a ROM chip in the device itself.
Your computer must be on the same IP subnet to connect to the web-based utility.
• Make sure you have an updated Java-enabled web browser. We recommend the following:
• Internet Explorer 6.0 or higher
• Netscape 8 or higher
• Mozilla 1.7.1ꢀ (5.0) or higher
• Opera 8.5 or higher
• Safari 1.ꢀ or higher (with Java 1.3.1 or higher)
• Camino 0.8.4 or higher
• Firefox 1.5 or higher
• Verify physical connectivity by checking for solid link lights on the device. If you do not get a solid link light, try using
a different cable or connect to a different port on the device if possible. If the computer is turned off, the link light may
not be on.
• Disable any Internet security software running on the computer. Software firewalls such as Zone Alarm, Black Ice,
Sygate, Norton Personal Firewall, and Windows® XP firewall may block access to the configuration pages. Check the
help files included with your firewall software for more information on disabling or configuring it.

• Configure your Internet settings:
• Go to Start > Settings > Control Panel. Double-click the Internet Options Icon. From the Security tab,
click the button to restore the settings to their defaults.
• Click the Connection tab and set the dial-up option to Never Dial a Connection. Click the LAN Settings
button. Make sure nothing is checked. Click OK.
• Go to the Advanced tab and click the button to restore these settings to their defaults. Click OK three
times.
• Close your web browser (if open) and open it.
• Access the web management. Open your web browser and enter the IP address of your D-Link router in the
address bar. This should open the login page for your the web management.
• If you still cannot access the configuration, unplug the power to the router for 10 seconds and plug back in. Wait
about 30 seconds and try accessing the configuration. If you have multiple computers, try connecting using a
different computer.
2. What can I do if I forgot my password?
If you forgot your password, you must reset your router. Unfortunately this process will change all your settings back
to the factory defaults.
To reset the router, locate the reset button (hole) on the rear panel of the unit. With the router powered on, use a
paperclip to hold the button down for 10 seconds. Release the button and the router will go through its reboot process.
Wait about 30 seconds to access the router. For information about logging into the router see page 1ꢀ.

Appendix A - Networking Basics
Networking Basics
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 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.

Appendix A - Networking Basics
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 on Start > Control Panel > Network Connections.
Windows® ꢀ000 - From the desktop, right-click My Network Places > Properties.
Step 2
Right-click on the Local Area Connection which represents your D-Link network adapter and select Properties.
Step 3
Highlight Internet Protocol (TCP/IP) and click Properties.
Step 4
Click 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 19ꢀ.168.0.1, make your IP address
19ꢀ.168.0.X where X is a number between ꢀ and 99. Make sure that the number
you choose is not in use on the network. Set Default Gateway the same as the LAN
IP address of your router (19ꢀ.168.0.1).
Set Primary DNS the same as the LAN IP address of your router (19ꢀ.168.0.1).The
Secondary DNS is not needed or you may enter a DNS server from your ISP.
Step 5
Click OK twice to save your settings.
