Section 1 - Product Overview
Introduction
Now you can monitor and manage your home network right from your laptop, iPhone®, iPad®, or Android™ device. This cloud-
enabled router can be congured to send an email anywhere, anytime, to keep you informed when new devices are connecting
to your network or intruders are detected. With the new graphical user interface, monitor in real-time websites that are being
visited with recent browser history displayed on the mydlink™ Lite app – great for parents on the go. The D-Link Cloud service
can also detect and block cyber criminals from breaking into your wireless network and suspicious activities will be displayed
right on your web browser or in the mydlink™ Lite app.
The D-Link DIR-850L is an IEEE 802.11ac compliant device that delivers up to 3 times faster speeds than 802.11n while staying
backward compatible with 802.11a/g/b devices. Connect the DIR-850L to a cable or DSL modem and share high-speed Internet
access to PCs, game consoles, and media players. Create a secure wireless network to share photos, les, music, videos, printers,
and network storage to your mobile devices. Powered by the 802.11ac technology and equipped with two 2.4 GHz and 5 GHz
dual-band internal antennas, this router provides superior wireless coverage for larger homes and oces, or for users running
bandwidth-intensive applications. The DIR-850L also includes a 4-port 10/100/1000 gigabit switch that connects gigabit-wired
devices for enjoying lag-free HD movie streaming, network gaming, and fast le transfers.
D-Link has created SharePort technology to bring more exibility to your network. With SharePort technology, you can connect
a USB printer and share it throughout your network. You can also share a USB storage device, providing network storage for
everyone to share. On top of that, you can share and access media stored on your USB storage remotely over the Internet with
the free mydlink SharePort app for mobile devices!
With some routers, all wired and wireless trac, including VoIP, video streaming, online gaming, and web browsing are mixed
together into a single data stream. By handling data this way, applications like video streaming could pause or delay. With the
D-Link Intelligent QoS technology, wired and wireless trac are analyzed and separated into multiple data streams.
For peace of mind, the DIR-850L supports the latest wireless security features to help prevent unauthorized access, be it from
over a wireless network or the Internet. Support for WPA™ and WPA2™ standards ensure that you will be able to use the best
possible encryption regardless of your client devices. In addition, this router utilizes dual-active rewalls (SPI and NAT) to
prevent potential attacks from across the Internet for the ideal centerpiece of your home or oce wireless network.

* Maximum wireless signal rate derived from IEEE Standard 802.11a, 802.11g, 802.11n and 802.11ac specications. Actual data throughput will vary. Network conditions and
environmental factors, including volume of network trac, building materials and construction, and network overhead, lower actual data throughput rate. Environmental
conditions will adversely aect wireless signal range.

Section 2 - Installation
Before you Begin
Installation
This section will walk you through the installation process. Placement of the router is very important. Do not place the router
in an enclosed area such as a closet, cabinet, or in the attic or garage.
• Please congure the router with the computer that was last connected directly to your modem.
• 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 ISP to change connection
types (USB to Ethernet).
• 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.

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, 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 (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 (.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 in not in use.

1. Turn o and unplug your cable or DSL broadband modem. This is required.
Hardware Installation
2. Position your router close to your modem and a computer. Place the router in an open area of your intended
work area for better wireless coverage.
3. Unplug the Ethernet cable that is connected to your computer from your modem (or existing router if upgrading).
Plug it into the LAN port labeled 1 on the back of your router. The router is now connected to your computer.

4. Plug one end of the included blue Ethernet cable that came with your router into the yellow port labeled
INTERNET on the back of the router. Plug the other end of this cable into the Ethernet port on your modem.
5. Reconnect the power adapter to your cable or DSL broadband modem and wait for two minutes.
6. Connect the supplied power adapter into the power port on the back of the router and then plug it into a power
outlet or surge protector. Press the power button and verify that the power LED is lit. Allow 1 minute for the
router to boot up.
7. If you are connecting to a broadband service that uses a dynamic connection (not PPPoE), you may be online
already. Try opening a web browser and enter a web site. A solid light indicates a connection on the Internet port
and the router can connect to the Internet. If the LED is orange, the connection is good but the router cannot
connect to the Internet.
