Using the DIR-822 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).

Secure Wireless Connection
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.

Advanced Capabilities of Wireless Network
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.

Security
The wireless router DIR-822 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.

Easy configuration and update
You can configure the settings of the wireless router DIR-822 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-822 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-822 supports configuration and management via 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.
