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 b\
e 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 maximi\
zing 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.

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. 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

Section 2 - Installation
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://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.

6. Disconnect the Ethernet cable from the router and reconnect your compute\
r to your network. 
7. Connect an Ethernet cable in one of the LAN ports of the router and connect it to your other router. Do not plug anything into the 
Internet port of the D-Link router. 
8. You may now use the other 3 LAN ports to connect other Ethernet devices and computers. To configure your wireless network, 
open a web browser and enter the IP address you assigned to the router. Refer to the Configuration and Wireless Security sections 
for more information on setting up your wireless network.
