Section 1 - Product Overview
Introduction
The D-Link DIR-879 is a wireless IEEE 802.11ac compliant device that delivers up to 3x faster speeds than 802.11n while staying
backward compatible with 802.11n/g/b/a devices. This means you can connect the DIR-879 to a cable or DSL modem and
provide high-speed Internet access to multiple computers, game consoles, and media players. You can create a secure wireless
network to share photos, les, music, videos, printers, and network storage. Powered by 802.11ac technology and equipped
with four external antennas, this router provides superior wireless coverage for larger homes and oces, or for users running
bandwidth-intensive applications. The DIR-879 also includes a 4-port 10/100/1000 Gigabit Ethernet switch that connects to
wired devices for uninterrupted video calling and faster le transfers.
D-Link Intelligent QoS Technology helps to increase network eciency by analyzing wired and wireless network trac and
prioritizing it in order of importance. This way, important network trac such as VoIP and video streaming, take priority over
background network trac such as a le downloads and print tasks, ensuring you have optimal network performance.
The DIR-879 supports the latest wireless security features to help prevent unauthorized access, be it from over a wireless
network or the Internet. Support for WPA™ and WPA2™ standards ensure that you will be able to use the best possible
encryption regardless of your client devices. In addition, this router is equipped with a dual-active rewall (SPI and NAT) to
prevent potential attacks over the Internet.
3D-Link DIR-879 User Manual
Section 1 - Product Overview
• Ultimate Fast Wireless Networking - The DIR-879 provides up to 600 Mbps wireless connection in 2.4 GHz
band, and up to 1300 Mbps* wireless connection in 5 GHz with other 802.11ac and 802.11n wireless clients. This
capability allows users to participate in real-time activities online, such as video streaming, online gaming, and
real-time audio. The performance of this 802.11ac wireless router gives you the freedom of wireless networking
at speeds 3x faster than 802.11n.
• Compatible with 802.11ac/n/g/b/a Wireless Devices - The DIR-879 is still fully compatible with the IEEE
802.11a, IEEE 802.11b, 802.11g and 802.11n, so it can connect with existing 802.11a, IEEE 802.11b, 802.11g and
802.11n PCI, USB, and CardBus adapters.
• Advanced Firewall Features - The web-based user interface displays a number of advanced network
management features including:
• Content Filtering - Easily applied content ltering based on MAC address, URL, and/or domain
name.
Features
• Filter Scheduling - These lters can be scheduled to be active on certain days or for a duration of
hours or minutes.
• Secure Multiple/Concurrent Sessions - The DIR-879 can pass through VPN sessions. It supports
multiple and concurrent IPSec and PPTP sessions, so users behind the DIR-879 can securely access
corporate networks.
• User-friendly Setup Wizard - Through its easy-to-use web-based user interface, the DIR-879 lets you control
what information is accessible to those on the wireless network, whether from the Internet or from your
company’s server. Congure your router to your specic settings within minutes.
* Maximum wireless signal rate derived from IEEE Standard 802.11a, 802.11g, 802.11n and 802.11ac 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.

Section 2 - Installation
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, attic, or garage.
Note: This installation section is written for users who are replacing their existing networking equipment or adding a router to
their exisitng setup. If you are setting up Internet service for the rst time, you may need to modify these steps.
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 Internet Service
Provider (ISP) to change connection types (USB to Ethernet).
• If connecting to a DSL modem, make sure to have your DSL service information provided by your Internet Service
Provider handy. This information is likely to include your DSL account's Username and Password. Your ISP may also
supply you with additional WAN conguration settings which might be necessary to establish a connection.
• If you are connecting a considerable amount of networking equipment, it may be a good idea to take the time to
label each cable or take a picture of your existing setup before making any changes.
• We suggest setting up your DIR-879 from a single device and verifying that it is connected to the Internet before
connecting additional devices.
• 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.

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 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 (0.5 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 2.4 GHz 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 2.4
GHz 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
Manual Setup
1. Turn o and unplug your cable or DSL broadband modem. This is required.
2. Position your router close to your modem and a computer. Place the router in an open area of your intended
work area for better wireless coverage.
3. Unplug the Ethernet cable from your modem (or existing router if upgrading) that is connected to your
computer. Plug it into the LAN port labeled 1 on the back of your router. The router is now connected to your
computer.
4. Plug one end of the included blue Ethernet cable that came with your router into the yellow port labeled
INTERNET on the back of the router. Plug the other end of this cable into the Ethernet port on your modem.
5. Reconnect the power adapter to your cable or DSL broadband modem and wait for two minutes.
6. Connect the supplied power adapter into the power port on the back of the router and then plug it into a
power outlet or surge protector. Press the power button and verify that the power LED is lit. Allow 1 minute for
the router to boot up.
7. If you are connecting to a broadband service that uses a dynamic connection (not PPPoE), you may be online
already. Try opening a web browser and connecting to a website. If the Internet LED indicator is lit, indicating a
connection on the Internet/WAN port, then the router should be able to connect to the Internet.
