CHAPTER 2. OVERVIEW

General Information

The DIR-853 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-853 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-853 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 1300Mbps2).

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.

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. 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-853 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.

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 450Mbps for 2.4GHz and up to 867Mbps for 5GHz.

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.

The router also supports the SafeDNS/SkyDNS web content filtering services, which provide more

settings and opportunities for safer Internet experience for home users of all ages and for

professional activities of corporate users.

You can configure the settings of the wireless router DIR-853 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-853 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-853 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.

IGMP/ALG/Passthrough

On the Advanced / IGMP/ALG/Passthrough page, you can allow the router to use IGMP and

RTSP, enable the SIP ALG and PPPoE/PPTP/L2TP/IPsec pass through functions.

IGMP is used for managing multicast traffic (transferring data to a group of destinations). This

protocol allows using network resources for some applications, e.g., for streaming video, more

efficiently.

SIP is used for creating, modifying, and terminating communication sessions. This protocol allows

telephone calls via the Internet.

RTSP is used for real-time streaming multimedia data delivery. This protocol allows some

applications to receive streaming audio/video from the Internet.

The PPPoE pass through function allows PPPoE clients of computers from your LAN to connect to

the Internet through connections of the router.

The PPTP pass through, L2TP pass through and IPsec pass through functions allow VPN PPTP,

L2TP and IPsec traffic to pass through the router so that clients from your LAN can establish

relevant connections with remote networks.

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 Firewall / DMZ page, you can specify the IP address of the DMZ host.

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 Firewall / DMZ page.

To disable the DMZ, move the Enable switch to the left and click the APPLY button.

Wireless Installation Considerations

The DIR-853 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-853 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.
