Section 1 - Product Overview
Introduction
TOTAL PERFORMANCE
Combines award winning router features and IEEE 802.11a/g/n wireless technology to provide the best wireless performance.
TOTAL SECURITY
The most complete set of security features including Active Firewall and WPA/WPA2 to protect your network against outside intruders.
TOTAL COVERAGE
Provides greater wireless signal rates even at farther distances for best-in-class Whole Home Coverage.
ULTIMATE PERFORMANCE
The D-Link Xtreme N® Dual Band Gigabit Router (DIR-825) is a 802.11n/802.11a compliant device that delivers real world performance of
up to 14x faster than an 802.11g wireless connection (also faster than a 100Mbps wired Ethernet connection). Create a secure wireless
network to share photos, les, music, video, printers, and network storage throughout your home. Connect the DIR-825 router to a cable
or DSL modem and share your high-speed Internet access with everyone on the network. In addition, this Router includes a Quality
of Service (QoS) engine that keeps digital phone calls (VoIP) and online gaming smooth and responsive, providing a better Internet
experience.
EXTENDED WHOLE HOME COVERAGE
Powered by Wireless N technology, this high performance router provides superior Whole Home Coverage while reducing dead spots.
The router is designed for use in bigger homes and for users who demand higher performance networking. Add a Wireless N notebook
or desktop adapter and stay connected to your network from virtually anywhere in your home.
TOTAL NETWORK SECURITY
The Wireless N router supports all of the latest wireless security features to prevent unauthorized access, be it from over the wireless
network or from the Internet. Support for WPA/WPA2 standards ensure that you’ll be able to use the best possible encryption method,
regardless of your client devices. In addition, this router utilizes dual active rewalls (SPI and NAT) to prevent potential attacks from
across the Internet.
* Maximum wireless signal rate derived from IEEE Standard 802.11a, 802.11g and 802.11n specications. Actual data throughput will vary. Network conditions and environmental
factors, including volume of network trac, building materials and construction, and network overhead, lower actual data throughput rate. Environmental conditions will
adversely aect wireless signal range.
3D-Link DIR-825 User Manual
Section 1 - Product Overview
• Faster Wireless Networking - The DIR-825 provides up to 300Mbps* wireless connection with other 802.11n
wireless clients. This capability allows users to participate in real-time activities online, such as video streaming,

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.
™
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 conguration 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 in one of the LAN ports of the router and connect it to your other router. Do not plug anything
into the Internet (WAN) port of the D-Link router.
8. You may now use the other 3 LAN ports to connect other Ethernet devices and computers. To congure your wireless network,
open a web browser and enter the IP address you assigned to the router. Refer to the Conguration and Wireless Security
sections for more information on setting up your wireless network.
