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 1167Mbps
).
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.
