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 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.

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.

DHCP stands for Dynamic Host Control Protocol. The DIR-855 has a built-in DHCP server. The DHCP Server will
automatically assign an IP address to the computers on the LAN/private network. Be sure to set your computers to be
DHCP clients by setting their TCP/IP settings to “Obtain an IP Address Automatically.” When you turn your computers
on, they will automatically load the proper TCP/IP settings provided by the DIR-855. The DHCP Server will automatically
allocate an unused IP address from the IP address pool to the requesting computer. You must specify the starting and
ending address of the IP address pool.

Section 3 - Configuration
The DIR-855 can be configured as a virtual server so that remote users accessing Web or FTP services via the public
IP address can be automatically redirected to local servers in the LAN (Local Area Network).
The DIR-855 firewall feature filters out unrecognized packets to protect your LAN network so all computers networked
with the DIR-855 are invisible to the outside world. If you wish, you can make some of the LAN computers accessible
from the Internet by enabling Virtual Server. Depending on the requested service, the DIR-855 redirects the external
service request to the appropriate server within the LAN network.
The DIR-855 is also capable of port-redirection meaning incoming traffic to a particular port may be redirected to a
different port on the server computer.
Each virtual service that is created will be listed at the bottom of the screen in the Virtual Servers List. There are
pre-defined virtual services already in the table. You may use them by enabling them and assigning the server IP to
use that particular virtual service.

QoS Engine
This option is disabled by default. Enable this
option for better performance and experience with
online games and other interactive applications,
such as VoIP.
This option should be enabled when you have a
slow Internet uplink. It helps to reduce the impact
that large low priority network packets can have
on more urgent ones.
This option is enabled by default when the QoS
Engine option is enabled. This option will allow
your router to automatically determine the uplink
speed of your Internet connection.
This displays the detected uplink speed.
The speed at which data can be transferred from the router to your ISP. This is determined by your ISP. ISP’s often speed as
a download/upload pair. For example, 1.5Mbits/284Kbits. Using this example, you would enter 284. Alternatively you can test
your uplink speed with a service such as www.dslreports.com.
By default, the router automatically determines whether the underlying connection is an xDSL/Frame-relay network or some
other connection type (such as cable modem or Ethernet), and it displays the result as Detected xDSL or Frame Relay Network.
If you have an unusual network connection in which you are actually connected via xDSL but for which you configure either
“Static” or “DHCP” in the Internet settings, setting this option to xDSL or Other Frame Relay Network ensures that the router
will recognize that it needs to shape traffic slightly differently in order to give the best performance. Choosing xDSL or Other
Frame Relay Network causes the measured uplink speed to be reported slightly lower than before on such connections, but
gives much better results.
When Connection Type is set to automatic, the automatically detected connection type is displayed here.
