User Manual Overview
CHAP ER 2. OVERVIEW
General Information
The DIR-820 device is a wireless dual band router with a built-in 3-port switch. It provides a fast
and simple way to create a wireless and wired network at home or in an office.
You can use any Ethernet port of the router as LAN or WAN port. The new-generation firmware
supports assigning several WAN ports for example in order to configure the primary and backup
WAN connection of different ISPs.
You are able to connect the wireless router DIR-820 to a cable or DSL modem or to a private
Ethernet line and use a high-speed Internet connection to successfully fulfill a wide range of
professional tasks. The built-in 3-port switch enables you to connect Ethernet-enabled computers
game consoles and other devices to your network.
Using the DIR-820 device you are able to quickly create a high-speed wireless network at home or
in your office which lets computers and mobile devices access the Internet virtually anywhere
(within the operational range of your wireless network). Simultaneous activity of 2.4GHz band and
5GHz band allows performing a wide range of tasks. The router can operate as a base station for
connecting wireless devices of the standards 802.11a 802.11b 802.11g 802.11n and 802.11ac (at
the wireless connection rate up to 1167Mbps1).
The router supports multiple functions for the wireless interface: several security standards (WEP
WPA/WPA2) MAC address filtering WPS WMM.
Multi-user MIMO technology allows to distribute the router's resources to let multiple wireless
clients use the Wi-Fi network efficiently keeping high rates for HD media streaming lag-free
gaming and fast transfer of large files.
Transmit Beamforming technology allows to flexibly change the antennas' radiation pattern and to
redistribute the signal directly to wireless devices connected to the router.
Smart adjustment of Wi-Fi clients is useful for networks based on several D-Link access points or
routers – when the smart adjustment function is configured on each of them a client always
connects to the access point (router) with the highest signal level.
Support of guest Wi-Fi network allows you to create a separate wireless network with individual
security settings. Devices connected to the guest network will be able to access the Internet but will
be isolated from the devices and resources of the router's LAN.
The wireless router DIR-820 includes a built-in firewall. The advanced security functions minimize
threats of hacker attacks prevent unwanted intrusions to your network and block access to
unwanted websites for users of your LAN.
The SSH protocol support provides more secure remote configuration and management of the
router due to encryption of all transmitted traffic including passwords.
Now the schedules are also implemented; they can be applied to the rules and settings of the
firewall and used to reboot the router at the specified time or every specified time period and to
enable/disable the wireless network and the Wi-Fi filter.
1 Up to 300Mbps for 2.4GHz and up to 867Mbps for 5GHz.

DIR-820 AC1200 Wave 2 MU-MIMO Wi-Fi Router
User Manual Overview
You can configure the settings of the wireless router DIR-820 via the user-friendly web-based
interface (the interface is available in several languages).
The configuration wizard allows you to quickly switch DIR-820 to one of the following modes:
router (for connection to a wired or wireless ISP) access point repeater or client and then
configure all needed setting for operation in the selected mode in several simple steps.
Also DIR-820 supports configuration and management via mobile application for Android and
iPhone smartphones.
You can simply update the firmware: the router itself finds approved firmware on D-Link update
server and notifies when ready to install it.

CHAP ER 3. INS ALLA ION AND CONNEC ION
Before You Begin
Please read this manual prior to installing the device. Make sure that you have all the necessary
information and equipment.
Computer or Mobile evice
Configuration of the wireless dual band router with a built-in 3-port switch DIR-820 (hereinafter
referred to as “the router”) is performed via the built-in web-based interface. The web-based
interface is available from any operating system that supports a web browser.
Also you can use D-Link Assistant application for Android or iPhone mobile devices (smartphones
or tablets).
PC Web Browser
The following web browsers are recommended:
•Apple Safari 8 and later
•Google Chrome 48 and later
•Microsoft Internet Explorer 10 and later
•Microsoft Edge 20.10240 and later
•Mozilla Firefox 44 and later
•Opera 35 and later.
For successful operation JavaScript should be enabled on the web browser. Make sure that
JavaScript has not been disabled by other software (such as virus protection or web user security
packages) running on your computer.
Wired or Wireless NIC (Ethernet or Wi-Fi Adapter)
Any computer that uses the router should be equipped with an Ethernet or Wi-Fi adapter (NIC). If
your computer is not equipped with such a device install an Ethernet or Wi-Fi adapter prior to
using the router.
Wireless Connection
Wireless workstations from your network should be equipped with a wireless 802.11a b g n or ac
NIC (Wi-Fi adapter). In addition you should specify the values of SSID channel number and
security settings defined in the web-based interface of the router for all these wireless workstations.

User Manual Installation and Connection
Connecting to PC
PC with Ethernet Adapter
1. Connect an Ethernet cable between any of LAN ports located on the back panel of the router
and the Ethernet port of your PC.
2. Connect the power cord to the power connector port on the back panel of the router then
plug the power adapter into an electrical outlet or power strip.
Then make sure that your PC is configured to obtain an IP address automatically (as DHCP client).
Obtaining IP Address Automatically (OS indows 7)
1. Click the Start button and proceed to the Control Panel window.
2. Select the Network and Sharing Center section. (If the Control Panel has the category
view (the Category value is selected from the View by drop-down list in the top right
corner of the window) choose the View network status and tasks line under the
