User Manual Overview
CHAP ER 2. OVERVIEW
General Information
The DIR-842 device is a wireless dual band gigabit router with a built-in 4-port switch. It provides a
fast and simple way to create a wireless and wired network at home or in an office.
Also you are able to connect the wireless router DIR-842 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 4-port switch enables you to connect Ethernet-enabled computers
game consoles and other devices to your network.
Using the DIR-842 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/WPA3) MAC address filtering WPS WMM.
In addition the device is equipped with a button for switching the Wi-Fi network off/on. If needed
for example when you leave home you can easily switch the router’s WLAN by pressing the
button and devices connected to the LAN ports of the router will stay online.
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 and maximum rate limitation. 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-842 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.
In addition the router supports IPsec and allows to create secure VPN tunnels.
Built-in Yandex.DNS service protects against malicious and fraudulent web sites and helps to block
access to adult content on children's devices.
You can configure the settings of the wireless router DIR-842 via the user-friendly web-based
interface (the interface is available in several languages).
1 Up to 300Mbps for 2.4GHz and up to 867Mbps for 5GHz.

User Manual Overview
The configuration wizard allows you to quickly switch DIR-842 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-842 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.
