Overview
CHAP ER 2. OVERVIEW
General Information
The DIR-825 device is a wireless dual band gigabit router with 3G/LTE support. It provides a fast
and simple way to create a wireless and wired network at home or in an office.
The router is equipped with a USB port for connecting a USB modem1 which can be used to
establish connection to the Internet. In addition to the USB port of the router you can connect a
USB storage device which will be used as a network drive.
In order to use the multifunction USB port effectively the router supports simultaneous operation of
several USB devices. For example you can access multimedia content of the connected HDD
storage and at the same time share a USB modem.2
Also you are able to connect the wireless router DIR-825 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-825 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 1167Mbps3).
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.
The EasyMesh function is D-Link implementation of mesh networks designed to quickly connect
several4 devices into one transport network for example when it's required to provide high-quality
Wi-Fi coverage without dead zones in living units of complicated planning or it's needed to create a
large temporary Wi-Fi network for an outdoor event.
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.
1 Not included in the delivery package. D-Link does not guarantee compatibility with all USB modems. For the list of
supported USB modems see the Specifications section page 8.
2 When using a USB hub with external power supply.
3 Up to 300Mbps for 2.4GHz and up to 867Mbps for 5GHz.
4 Up to 6 devices.

User Manual
Overview
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-825 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 upon configuration of an IPsec tunnel.
Built-in Yandex.DNS service protects against malicious and fraudulent web sites and helps to block
access to adult content on children's devices.
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.
The new ad blocking function effectively blocks advertisements which appear during web surfing.
You can configure the settings of the wireless router DIR-825 via the user-friendly web-based
interface (the interface is available in several languages).
The Setup Wizard allows you to quickly switch DIR-825 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-825 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.
