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.
Before you Begin
• Please congure 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 o 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.

Section 2 - Installation
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 dierence. A solid metal door or aluminum studs may have a negative eect 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 (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
Connect to an Existing Router
Note: It is strongly recommended to replace your existing router with the DIR-825 instead of using both. If your modem is a combo
router, you may want to contact your ISP or manufacturer’s user guide to put the router into Bridge mode, which will ‘turn o’ the
router (NAT) functions.
If you are connecting the DIR-825 router to an existing router to use as a wireless access point and/or switch, you will have to
do the following to the DIR-825 before connecting it 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, 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.

Section 4 - Security
Wireless Security
This section will show you the dierent levels of security you can use to protect your data from intruders. The DIR-825 oers the following
types of security:
• WPA2 (Wi-Fi Protected Access 2) • WPA2-PSK (Pre-Shared Key)
• WPA (Wi-Fi Protected Access) • WPA-PSK (Pre-Shared Key)
What is WPA?
WPA (Wi-Fi Protected Access), is a Wi-Fi standard that was designed to improve the security features of WEP (Wired Equivalent Privacy).
The 2 major improvements over WEP:
• Improved data encryption through the Temporal Key Integrity Protocol (TKIP). TKIP scrambles the keys using a hashing
algorithm and, by adding an integrity-checking feature, ensures that the keys haven’t been tampered with. WPA2 is
based on 802.11i and uses Advanced Encryption Standard (AES) instead of TKIP.
• User authentication, which is generally missing in WEP, through the extensible authentication protocol (EAP). WEP
regulates access to a wireless network based on a computer’s hardware-specic MAC address, which is relatively simple
to be snied out and stolen. EAP is built on a more secure public-key encryption system to ensure that only authorized
network users can access the network.
WPA-PSK/WPA2-PSK uses a passphrase or key to authenticate your wireless connection. The key is an alpha-numeric password between
8 and 63 characters long. The password can include symbols (!?*&_) and spaces. This key must be the exact same key entered on your
wireless router or access point.
WPA/WPA2 incorporates user authentication through the Extensible Authentication Protocol (EAP). EAP is built on a more secure public
key encryption system to ensure that only authorized network users can access the network.

SPI (Stateful Packet Inspection, also known as dynamic packet ltering)
helps to prevent cyber attacks by tracking more state per session. It
validates that the trac passing through the session conforms to the
protocol.
Enable this feature to protect your network from certain kinds of
“spoong” attacks.
If an application has trouble working from behind the router, you can
expose one computer to the Internet and run the application on that
computer.
Note: Placing a computer in the DMZ may expose that computer to a
variety of security risks. Use of this option is only recommended as a last
resort.
Specify the IP address of the computer on the LAN that you want to have
unrestricted Internet communication. If this computer obtains it’s IP
address automatically using DHCP, be sure to make a static reservation
on the Setup > Network Settings page so that the IP address of the
DMZ machine does not change.
PPTP:
