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 an 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 is not in use.

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
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. Skip to page 14 to configure your router.
Connect to Cable/DSL/Satellite Modem

12D-Link DIR-685 User Manual
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. Type in the Captcha phrase and 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.
Connect to Another Router

Section 2 - Installation
6. Disconnect the Ethernet cable from the router and reconnect your computer 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 three 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.
