DIR-825/AC Wireless AC1200 Dual Band Gigabit Router
Overview
CHAPTER 2. OVERVIEW
General Information
The DIR-825/AC 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, or a printer.
Also you are able to connect the wireless router DIR-825/AC 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/AC 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 1167Mbps2).
The router supports multiple functions for the wireless interface: several security 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 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.
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.
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-825/AC 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.
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 Up to 300Mbps for 2.4GHz and up to 867Mbps for 5GHz.

DIR-825/AC Wireless AC1200 Dual Band Gigabit Router
Overview
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-825/AC via the user-friendly web-based
interface (the interface is available in two languages – in Russian and in English).
The configuration wizard allows you to quickly switch DIR-825/AC 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/AC supports configuration and management via D-Link Click'n'Connect mobile
application for Android 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.
