Section 1 - Product Overview
Introduction
The D-Link DIR-853 AC1300 MU-MIMO Wi-Fi Gigabit Router shares your Internet connection over a blazing-fast Gigabit
Wireless AC connection of up to 1300 Mbps (Up to 867 Mbps 5 GHz Wireless AC and up to 400 Mbps 2.4 GHz Wireless N)1, using
advanced AC beamforming technology to signicantly outperform 802.11n and other 802.11ac devices. Equipped with one
Gigabit WAN/Internet port and four Gigabit LAN ports to provide wired speeds of up to 10 times faster than standard 10/100
ports, the DIR-853 creates the best networking experience to date.
Featuring four antennas and a 2x2+2x2 MU-MIMO (Multi-User Multiple In Multiple Out) antenna conguration, the DIR-853
oers better data rates, fewer dead-spots, more coverage, and higher reliability. Operating exclusively in the 5 GHz band, the
DIR-853's 802.11ac wireless connections avoid the crowded 2.4 GHz band, allowing you faster speeds while still maintaining
backwards compatibility with older 802.11n/g/b devices. The DIR-853 prepares your home to become a Connected Home by
bringing Wi-Fi to places your old signal can’t reach. A stronger Wi-Fi signal means you can install more wireless surveillance
cameras, baby monitors, sensors, and alarms in the places where you need them.
The DIR-853's Smart Connect Technology makes connecting to wireless networks easy by eliminating the confusion of multiple

or 2.4 GHz band network would provide them with better range and speed. Smart Connect simplies this by only presenting
a single wireless network for you to connect to. Behind the scenes, when a connection is initiated, the DIR-853's advanced
algorithms determine the best band for your device to connect to, automatically distributing devices to the optimal band,
thereby ensuring a faster, more reliable, and hassle-free experience for all of your users and devices.
The DIR-853 AC1300 MU-MIMO Wi-Fi Gigabit Router provides incredible speeds, smart antenna technology, fast ports, cloud
features, and advanced security features. It also features an innovative design and easy installation options.

Section 3 - Installation
Before you Begin
• Placement of the router is very important. Do not place the router in an enclosed area such as a closet, cabinet,
attic, or garage. This is to allow proper ventilation and prevent overheating.
• Congure the router with the computer that was last connected directly to your Internet connection. Verify that it
is connected to the Internet before connecting additional devices.
• If your ISP provided you with a modem/router combo, you will need to set it to“bridge”mode so the router can
work properly. Please contact your ISP or refer to the user manual for your modem/router device.
• You can only use the Ethernet port on your modem. If you were using the USB connection before using the router,
then you must turn o your modem, disconnect the USB cable and connect an Ethernet cable to the Internet
port on the router, and then turn the modem back on. In some cases, you may need to call your Internet Service
Provider (ISP) to change connection types (USB to Ethernet).
• If connecting to a DSL modem, make sure to have your DSL service information provided by your Internet Service
Provider handy. This information is likely to include your DSL account's Username and Password. Your ISP may also
supply you with additional WAN conguration settings which might be necessary to establish a connection.
• If you are connecting a considerable amount of networking equipment, it may be a good idea to take the time to
label each cable or take a picture of your existing setup before making any changes.
• If you have DSL and are connecting via PPPoE, make sure you disable or uninstall any PPPoE software such as
WinPoET, BroadJump, or EnterNet 300 from your computer or you will not be able to connect to the Internet.
This section will walk you through the installation of the DIR-853.

Section 3 - Installation
Wireless Installation Considerations
The D-Link wireless router lets you access your network using a wireless connection from virtually anywhere within the
operating range of your wireless network. Keep in mind 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 (radio frequency) noise in your home or business. The key to maximizing wireless range is to
follow these basic guidelines:
1. Keep the number of walls and ceilings between the D-Link router and other network devices to a minimum -
each wall or ceiling can reduce your adapter’s range from 3-90 feet (1-30 meters.) Position your devices so that
the number of walls or ceilings is minimized.
2. Be aware of the direct line between network devices. A wall that is 1.5 feet thick (0.5 meters) at a 45-degree
angle appears to be almost 3 feet (1 meter) thick. At a 2-degree angle it looks over 42 feet (14 meters) thick!
Position devices so that the signal will travel straight through a wall or ceiling (instead of at an angle) for better
reception.
3. Building materials make a dierence. A solid metal door or aluminum studs may have a negative eect on
range. Try to position access points, wireless routers, and computers so that the signal passes through drywall or
open doorways. Materials and objects such as glass, steel, metal, walls with insulation, water (sh tanks), mirrors,
le cabinets, brick, and concrete will degrade your wireless signal.
4. Keep your product 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 (wireless products 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. The base transmits a signal even if the
phone is not in use.

Section 3 - Installation
2. Position your DIR-853 near your Internet-connected modem. Place it in an open area for better wireless coverage.
1. The DIR-853 is designed to give you the fastest, most stable network connection possible. In order to maximize
performance, fully extend the antennas into a 105 degree angle to provide optimal wireless coverage. Keep the router
in an open area for better wireless coverage.
3. Turn o and unplug the power and Ethernet cable to your cable or DSL broadband modem. This is required. In some
cases, you may need to turn it o for up to ve minutes.
