User Manual Overview
CHA TER 2. OVERVIEW
General Information
The DIR-878 device is a wireless dual band gigabit router with a built-in 4-port switch. It provides a
fast and simple wa to create a wireless and wired network at home or in an office.
You are able to connect the wireless router DIR-878 to a cable or DSL modem or to a private
Ethernet line and use a high-speed Internet connection to successfull fulfill a wide range of
professional tasks. The built-in 4-port switch enables ou to connect Ethernet-enabled computers,
game consoles, and other devices to our network.
Using the DIR-878 device, ou are able to quickl create a high-speed wireless network at home or
in our office, which lets computers and mobile devices access the Internet virtuall an where
(within the operational range of our wireless network). Simultaneous activit 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 1900Mbps1).
The router supports multiple functions for the wireless interface: several securit standards (WEP,
WPA/WPA2), 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 ou leave home, ou can easil switch the router’s WLAN b pressing the
button, and devices connected to the LAN ports of the router will sta online.
Multi-user MIMO technolog allows to distribute the router's resources to let multiple wireless
clients use the Wi-Fi network efficientl , keeping high rates for HD media streaming, lag-free
gaming, and fast transfer of large files.
Transmit Beamforming technolog allows to flexibl change the antennas' radiation pattern and to
redistribute the signal directl 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 alwa s
connects to the access point (router) with the highest signal level.
Support of guest Wi-Fi network allows ou to create a separate wireless network with individual
securit 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-878 includes a built-in firewall. The advanced securit functions minimize
threats of hacker attacks, prevent unwanted intrusions to our network, and block access to
unwanted websites for users of our 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.
The router also supports the Sk DNS web content filtering service, which provides more settings
and opportunities for safer Internet experience for home users of all ages and for professional
activities of corporate users.
1 Up to 600Mbps for 2.4GHz and up to 1300Mbps for 5GHz.

User Manual Overview
You can configure the settings of the wireless router DIR-878 via the user-friendl web-based
interface (the interface is available in two languages – in Russian and in English).
The configuration wizard allows ou to quickl switch DIR-878 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-878 supports configuration and management via mobile application for Android and
iPhone smartphones.
You can simpl update the firmware: the router itself finds approved firmware on D-Link update
server and notifies when read to install it.

2.4GHz band, a Wi-Fi client should support MIMO 3x3 and QAM256 modulation scheme. Actual data throughput will var . Network conditions
and environmental factors, including volume of network traffic, building materials and construction, and network overhead, lower actual data
throughput rate. Environmental factors will adversel affect wireless signal range.
