CHAPTER 2. OVERVIEW
General Information
The DIR-842V2 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-842V2 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-842V2 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 1166Mbps1).
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-842V2 includes a built-in firewall. The advanced security functions
minimize threats of hacker attacks, and prevent unwanted intrusions to your network.
The SSH protocol support provides more secure remote configuration and management of the
router due to encryption of all transmitted traffic, including passwords.
In addition, the router supports IPsec and allows to create secure VPN tunnels. Support of the IKEv2
protocol allows to provide simplified message exchange and use asymmetric authentication engine

Now the schedules are also implemented; they can be applied to the rules of various filters and used
to reboot the router at the specified time or every specified time period and to enable/disable the
wireless network.
You can configure the settings of the wireless router DIR-842V2 via the user-friendly web-based
interface (the interface is available in several languages).
The Setup Wizard allows you to quickly switch DIR-842V2 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-842V2 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.

DMZ
A DMZ is a host or network segment located “between” internal (local) and external (global)
networks. In the router, the DMZ implements the capability to transfer a request coming to a port of
the router from the external network to a specified host of the internal network.
On the Functions / Firewall / DMZ page, you can specify the IP address of the DMZ host.
Figure 99. The Functions / Firewall / DMZ page.
To enable the DMZ, move the Enable switch to the right.
Enter the IP address of a host from your network in the IP address field. To choose a device
connected to the router's LAN at the moment, select the relevant value from the drop-down list (the
field will be filled in automatically).
Move the Enable NAT Loopback switch to the right in order to let the users of the router's LAN
access the DMZ host using the external IP address of the router or its DDNS name (if a DDNS service
is configured). Users from the external network access the router using the same address (or DDNS
name).
Click the APPLY button.
Note that when the DMZ is enabled, all traffic coming to a port of the WAN interface of the router is
directed to the same port of the specified IP address. Also note that virtual servers have higher priority
than the DMZ host. In other words, if there has been created a virtual server that directs traffic from
external port 80 to a port of the device from the router's local network, then entering
http://router_WAN_IP in the address bar, users of the external network are directed to the
specified port and IP address configured for the virtual server, but not to port 80 of the device with
the IP address specified on the Functions / Firewall / DMZ page.
To disable the DMZ, move the Enable switch to the left and click the APPLY button.

Wireless Installation Considerations
The DIR-842V2 device 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 noise in your home or office. To maximize your wireless range, follow the guidelines below.
1. Keep the number of walls and ceilings between the DIR-842V2 device and other network
devices to a minimum – each wall or ceiling can reduce your wireless network range by 3- 90
feet (1-30 meters).
2. Be aware of the direct line between network devices. Place your devices so that the signal
travels straight through a wall or ceiling (instead of at an angle) for better reception.
3. Building materials make a difference. A solid metal door or aluminum studs may have a
negative effect on your wireless range. Try to position your router, access points, and
computers so that the signal passes through drywalls or open doorways. Materials and objects
such as glass, steel, metal, walls with insulation, water (fish tanks), mirrors, file cabinets, brick,
and concrete will degrade your wireless signal.
4. Keep your router 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 equipment (wireless devices 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. Note, that the base transmits a signal even if the phone in not in use.
