Section 2 - Installation
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 congure the router with the computer that was last connected directly to your modem. Also, you can only
use the Ethernet port on your modem when connecting the modem to the router. If you were using the modem’s USB
connection before using the router, then you must turn off your modem, disconnect the USB cable and connect an
Ethernet cable to the WAN 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 Ethernet 300 from your computer or you will not be able to connect to the Internet.

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 (sh tanks), mirrors, le 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 devices (wireless products that control devices
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.

12D-Link DIR-400 User Manual
Section 2 - Installation
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
WAN port on the router.
4. Plug the included 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 then plug it into an outlet or power strip. Wait about 30 seconds for the
router to boot.
7. Turn on your computer.
8. Verify the link lights on the router. The power light, WAN light, and the LAN light (the port that your computer is
plugged into) should be lit. If not, make sure your computer, modem, and router are powered on and verify that the
cable connections are correct.
9. Skip to page 15 to congure your router.
Connecting to a Cable/DSL/Satellite Modem

13D-Link DIR-400 User Manual
Section 2 - Installation
If you are connecting the D-Link router to another router for 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 adapter 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 OK 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 conguration 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 computer to your network.
7. Connect an Ethernet cable to one of the LAN ports of the router and connect it to your other router. Do not plug
anything into the WAN port of the D-Link router.
8. You may now use the other three LAN ports to connect other Ethernet devices and computers. To congure your
wireless network, open a web browser and enter the IP address you assigned to the router. Refer to the Conguration
and Wireless Security sections for more information on setting up your wireless network.
