Before you Begin

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.

• Please configure the router with the computer that was last connected directly to your modem.

• You can only use the Ethernet port on your modem. If you were using the USB connection before using

the router, then you must turn off your modem, disconnect the USB cable and connect an Ethernet cable

to the Internet port on the router, and then turn the modem back on. In some cases, you may need to

call your ISP to change connection types (USB to Ethernet).

•

If you have DSL and are connecting via PPPoE, make sure you disable or uninstall any PPPoE software

such as WinPoet, Broadjump, or Enternet 300 from your computer or you will not be able to connect to

the Internet.

• When running the Setup Wizard from the D-Link CD, make sure the computer you are running the CD

from is connected to the Internet and online or the wizard will not work. If you have disconnected any

hardware, re-connect your computer back to the modem and make sure you are online.

Wireless Installation Considerations

The D-Link wireless router lets you access your network using a wireless connection from virtually anywhere within

the operating range of your wireless network. Keep in mind, however, that the number, thickness and location of

walls, ceilings, or other objects that the wireless signals must pass through, may limit the range. Typical ranges vary

depending on the types of materials and background RF (radio frequency) noise in your home or business. The key

to maximizing wireless range is to follow these basic guidelines:

1

. Keep the number of walls and ceilings between the D-Link router and other network devices to a

minimum - each wall or ceiling can reduce your adapter’s range from 3-90 feet (1-30 meters.) Position

your devices so that the number of walls or ceilings is minimized.

2

. Be aware of the direct line between network devices. A wall that is 1.5 feet thick (.5 meters), at a

45-degree angle appears to be almost 3 feet (1 meter) thick. At a 2-degree angle it looks over 42 feet

(14 meters) thick! Position devices so that the signal will travel straight through a wall or ceiling (instead

of at an angle) for better reception.

3

. Building Materials make a difference. A solid metal door or aluminum studs may have a negative effect on

range. Try to position access points, wireless routers, and computers so that the signal passes through

drywall or open doorways. Materials and objects such as glass, steel, metal, walls with insulation, water

(fish tanks), mirrors, file cabinets, brick, and concrete will degrade your wireless signal.

4

. Keep your product away (at least 3-6 feet or 1-2 meters) from electrical devices or appliances that

generate RF noise.

5

. If you are using 2.4GHz cordless phones or X-10 (wireless products such as ceiling fans, lights, and

home security systems), your wireless connection may degrade dramatically or drop completely. Make

sure your 2.4GHz phone base is as far away from your wireless devices as possible. The base transmits

a signal even if the phone in not in use.

If you are connecting the router to a cable/DSL/satellite modem, please follow the steps below:

1. Place the router in an open and central location. Do not plug the power adapter into the router.

2. Turn the power off on your modem. If there is no on/off switch, then unplug the modem’s power adapter.

Shut down your computer.

3. Unplug the Ethernet cable (that connects your computer to your modem) from your computer and place

it into the Internet port on the router.

4. Plug an Ethernet cable into one of the four LAN ports on the router. Plug the other end into the Ethernet

port on your computer.

5. Turn on or plug in your modem. Wait for the modem to boot (about 30 seconds).

6. Plug the power adapter to the router and connect to an outlet or power strip. Wait about 30 seconds for

the router to boot.

7. Turn on your computer.

8. Refer to page 13 to configure your router.

If you are connecting the D-Link router to another router to use as a wireless access point and/or switch, you will have

to do the following before connecting the router to your network:

• Disable UPnP

™

• Disable DHCP

• Change the LAN IP address to an available address on your network. The LAN ports on the router cannot

accept a DHCP address from your other router.

To connect to another router, please follow the steps below:

1. Plug the power into the router. Connect one of your computers to the router (LAN port) using an Ethernet cable.

Make sure your IP address on the computer is 192.168.0.xxx (where xxx is between 2 and 254). Please see the

Networking Basics

section for more information. If you need to change the settings, write down your existing settings

before making any changes. In most cases, your computer should be set to receive an IP address automatically in

which case you will not have to do anything to your computer.

2. Open a web browser and enter

http://dlinkrouter or http://192.168.0.1

and press

Enter

. When the login window

appears, set the user name to

Admin

and leave the password box empty. Click

Log In

to continue.

3. Click on

Advanced

and then click

Advanced Network

. Uncheck the

Enable UPnP

checkbox. Click

Save Settings

to continue.

4. Click

Setup

and then click

Network Settings

. Uncheck the

Enable DHCP Server

checkbox. Click

Save Settings

to continue.

5. Under Router Settings, enter an available IP address and the subnet mask of your network. Click

Save Settings

to

save your settings. Use this new IP address to access the configuration utility of the router in the future. Close the

browser and change your computer’s IP settings back to the original values as in Step 1.
