Information you will need about your LAN or computer

:

Ethernet NIC

If your computer has an Ethernet NIC, you can connect the DSL-2542B to this Ethernet port using an Ethernet cable. You can also use the Ethernet

ports on the DSL-2542B to connect to other computer or Ethernet devices.

DHCP Client status

Your DSL-2542B 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-2542B 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 ADSL

connection in the future.

Once you have the above information, you are ready to setup and configure your DSL-2542B ADSL Router.

Device Installation

The DSL-2542B connects two separate physical interfaces, an ADSL (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. 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 Link/Act LED indicators 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 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. Press and hold the reset button while the device is powered off.

2. Turn on the power.

3. Wait for 5~8 seconds and then release the reset button.

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.

Setup

This section will show you how to set up and configure your new D-Link Router using the Web-based configuration utility.

Web-based Configuration Utility

Connect to the Router

To configure the WAN connection used by the Router it is first necessary to communicate with the Router through its management interface, which

is HTML-based and can be accessed using a web browser. The easiest way to make sure your computer has the correct IP settings is to configure

it to use the DHCP server in the Router. The next section describes how to change the IP configuration for a computer running a Windows operating

system to be a DHCP client.

To access the configuration utility, open a web-browser such as Internet

Explorer and enter the IP address of the router (

192.168.1.1

).

Type

“admin

” for the User Name and “

admin

” in the Password field. If

you get a Page Cannot be Displayed error, please refer to the

Troubleshooting section for assistance.

configure and monitor the Router including how to change IP settings and DHCP server setup.

QUICK SETUP

Click the

Setup Wizard

link in the middle of the top of the window of the

Router’s opening page to launch a series of setup windows.

Alternatively, you can tick the Manual Setup check box and click the

desired setting option radio button in the middle of the window. The

manual ADSL connection setup is described later in this manual.
