Section 1 - Product Overview
Introduction
Now you can monitor and manage your home network right from your laptop, iPhone®, iPad®, or Android™ device. The cloud-
enabled router can be congured to send an email to keep you informed anywhere, anytime when new devices are connecting
to your network or unwanted access is detected. Monitor in realtime websites that are being visited with recent browser history
displayed on the mydlink™ Lite app – which is great for parents. The D-Link Cloud Service can detect and block unwelcomed
guests who try to get into your wireless network and suspicious activities will be displayed right on your mydlink™ Lite app
or browser.
The D-Link DIR-850L is a 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 provide high-speed Internet
access to multiple computers, game consoles, and media players. Create a secure wireless network to share photos, les, music,
videos, printers, and network storage. Powered by the 802.11ac technology and equipped with six 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 network
gaming and faster 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.
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.
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 Firewalls (SPI and NAT) to prevent potential attacks
from across the Internet for the ideal centerpiece for your wireless network in the home or oce.

Section 1 - Product Overview
• Ultimate Fast Wireless Networking - The DIR-850L provides up to 300Mbps wireless connection in 2.4GHz band,
900Mbps wireless connection in 5GHz with other 802.11ac and draft 802.11n wireless clients. This capability
allows users to participate in real-time activities online, such as video streaming, online gaming, and real-time
audio. The performance of this 802.11ac wireless router gives you the freedom of wireless networking at speeds
3x faster than 802.11n.
• Compatible with 802.11a/g/n Devices - The DIR-850L is still fully compatible with the IEEE 802.11a, 802.11g
and 802.11n, so it can connect with existing 802.11a, 802.11g and 802.11n PCI, USB, and Cardbus adapters.
• Advanced Firewall Features - The Web-based user interface displays a number of advanced network
management features including:
• Content Filtering - Easily applied content ltering based on MAC Address, URL, and/or Domain
Name.
• Filter Scheduling - These lters can be scheduled to be active on certain days or for a duration of
hours or minutes.
• Secure Multiple/Concurrent Sessions - The DIR-850L can pass through VPN sessions. It supports
multiple and concurrent IPSec and PPTP sessions, so users behind the DIR-850L can securely access
corporate networks.
• User-friendly Setup Wizard - Through its easy-to-use Web-based user interface, the DIR-850L lets you control
what information is accessible to those on the wireless network, whether from the Internet or from your company’s
server. Congure your router to your specic settings within minutes.
* Maximum wireless signal rate derived from IEEE Standard 802.11a, 802.11g, 802.11n and draft 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.

Section 2 - 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, 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 2.4GHz 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 2.4GHz 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.

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. If a solid light indicates 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.

By default the wireless security of this router will be disabled. In this
next option the user can enabled or disable wireless security for the
frequency band 2.4GHz. There are two types of encryption that can be
used. WEP or WPA/WPA2.
Wireless Security Mode: WEP
Wired Equivalent Privacy (WEP) is the most basic form of encryption
that can be used for wireless networks. Even though it is known as a
‘weak’ security method, it is better than no security at all. Older wireless
adapter sometimes only supports WEP encryption and thus we still nd
this encryption method used today.
The following parameters will be available for conguration:
WEP Key Length: Here the user can specify to either use a
64Bit or a 128Bit encrypted key.
Authentication: Authentication is a process by which the
router veries the identity of a network
device that is attempting to join the wire-
less network. There are two types authen-
tication for this device when using WEP.
Open System allows all wireless devices
to communicate with the router before
they are required to provide the encryp-
tion key needed to gain access to the
network. Shared Key requires any wire-
less device attempting to communicate
with the router to provide the encryption
key needed to access the network before
they are allowed to communicate with the
router.
WEP Key 1: Enter the WEP key used here. For 64-bit keys you must enter 10 hex digits into each key box. For 128-bit keys you

may also enter any text string into a WEP key box, in which case it will be converted into a hexadecimal key using
the ASCII values of the characters. A maximum of 5 text characters can be entered for 64-bit keys, and a maximum
of 13 characters for 128-bit keys.

Wireless Security Mode: Enable WEP Wireless Security (basic)
Wired Equivalent Privacy (WEP) is the most basic form of encryption
that can be used for wireless networks. Even though it is known as a
‘weak’ security method, it is better than no security at all. Older wireless
adapter sometimes only supports WEP encryption and thus we still nd
this encryption method used today.
The following parameters will be available for conguration:
Authentication: Authentication is a process by which the
router veries the identity of a network
device that is attempting to join the wire-
less network. There are two types authen-

Open System allows all wireless devices
to communicate with the router before
they are required to provide the encryp-

Section 4 - Security
Wireless Security
This section will show you the dierent levels of security you can use to protect your data from intruders. The DIR-850L oers the
following types of security:
• WPA2 (Wi-Fi Protected Access 2) • WPA2-PSK (Pre-Shared Key)
• WPA (Wi-Fi Protected Access) • WPA-PSK (Pre-Shared Key)
What is WPA?
WPA (Wi-Fi Protected Access), is a Wi-Fi standard that was designed to improve the security features of WEP (Wired Equivalent Privacy).
The 2 major improvements over WEP:
• Improved data encryption through the Temporal Key Integrity Protocol (TKIP). TKIP scrambles the keys using a hashing
algorithm and, by adding an integrity-checking feature, ensures that the keys haven’t been tampered with. WPA2 is
based on 802.11i and uses Advanced Encryption Standard (AES) instead of TKIP.
• User authentication, which is generally missing in WEP, through the extensible authentication protocol (EAP). WEP
regulates access to a wireless network based on a computer’s hardware-specic MAC address, which is relatively simple
to be snied out and stolen. EAP is built on a more secure public-key encryption system to ensure that only authorized
network users can access the network.
WPA-PSK/WPA2-PSK uses a passphrase or key to authenticate your wireless connection. The key is an alpha-numeric password between
8 and 63 characters long. The password can include symbols (!?*&_) and spaces. This key must be the exact same key entered on your
wireless router or access point.
WPA/WPA2 incorporates user authentication through the Extensible Authentication Protocol (EAP). EAP is built on a more secure public
key encryption system to ensure that only authorized network users can access the network.

DHCP Server Settings
DHCP stands for Dynamic Host Control Protocol. The DIR-850L has a built-in DHCP server. The DHCP Server will automatically
assign an IP address to the computers on the LAN/private network. Be sure to set your computers to be DHCP clients by setting
their TCP/IP settings to “Obtain an IP Address Automatically.” When you turn your computers on, they will automatically load
the proper TCP/IP settings provided by the DIR-850L. The DHCP Server will automatically allocate an unused IP address from
the IP address pool to the requesting computer. You must specify the starting and ending address of the IP address pool.
Check this box to enable the DHCP server on your router.
Uncheck to disable this function.
Enter the starting and ending IP addresses for the DHCP
server’s IP assignment.
Note: If you statically (manually) assign IP addresses to your
computers or devices, make sure the IP addresses are outside
of this range or you may have an IP conict.
The length of time for the IP address lease. Enter the Lease
time in minutes.
If all the computers on the LAN successfully obtain their
IP addresses from the router’s DHCP server as expected,
this option can remain disabled. However, if one of the
computers on the LAN fails to obtain an IP address from the
router’s DHCP server, it may have an old DHCP client that
incorrectly turns o the broadcast ag of DHCP packets.
Enabling this option will cause the router to always broadcast its responses to all clients, thereby working around the problem, at
the cost of increased broadcast trac on the LAN.
Check this box to allow the DHCP Server to oer NetBIOS conguration settings to the LAN hosts. NetBIOS allow LAN hosts to
discover all other computers within the network, e.g. within Network Neighborhood.
If NetBIOS announcement is switched on, it will cause WINS information to be learned from the WAN side, if available. Turn this

QoS Engine
The QoS Engine option helps improve your network gaming performance by
prioritizing applications. By default the QoS Engine settings are disabled and
application priority is not classied automatically. The QoS section contains a
queuing mechanism, trac shaping and classication. It supports two kinds
of queuing mechanisms. Strict Priority Queue (SPQ) and Weighted Fair Queue
(WFQ). SPQ will process trac based on trac priority. Queue1 has the highest
priority and Queue4 has the lowest priority. WFQ will process trac based on
the queue weight. Users can congure each queue’s weight. The sum of all the queue’s weight must be 100. When surng the Internet, the system will do
trac shaping based on the uplink and downlink speed. The classication rules can be used to classify trac to dierent queues, then SPQ or WFQ will
do QoS based on the queue’s priority or weight.
The following parameters will be available for conguration:
Enable QoS: This option is disabled by default. Enable this option for
better performance and experience with online games and
other interactive applications, such as VoIP.
Uplink Speed: The speed at which data can be transferred from the
router to your ISP. This is determined by your ISP. ISP’s often

Troubleshooting
This chapter provides solutions to problems that can occur during the installation and operation of the DIR-850L. Read the
following descriptions if you are having problems. The examples below are illustrated in Windows® XP. If you have a dierent
operating system, the screenshots on your computer will look similar to the following examples.
1. Why can’t I access the web-based conguration utility?
When entering the IP address of the D-Link router (192.168.0.1 for example), you are not connecting to a website nor do you
have to be connected to the Internet. The device has the utility built-in to a ROM chip in the device itself. Your computer must
be on the same IP subnet to connect to the web-based utility.
• Make sure you have an updated Java-enabled web browser. We recommend the following:
- Microsoft Internet Explorer® 7 and higher
- Mozilla Firefox 3.5 and higher
- Google™ Chrome 8 and higher
- Apple Safari 4 and higher
• Verify physical connectivity by checking for solid link lights on the device. If you do not get a solid link light, try using a
dierent cable or connect to a dierent port on the device if possible. If the computer is turned o, the link light may not be
on.
• Disable any Internet security software running on the computer. Software rewalls such as Zone Alarm, Black Ice, Sygate,
Norton Personal Firewall, and Windows
®
XP rewall may block access to the conguration pages. Check the help les included
with your rewall software for more information on disabling or conguring it.

• Congure your Internet settings:
• Go to Start > Settings > Control Panel. Double-click the Internet Options Icon. From the Security tab, click
the button to restore the settings to their defaults.
• Click the Connection tab and set the dial-up option to Never Dial a Connection. Click the LAN Settings button.
Make sure nothing is checked. Click OK.
• Go to the Advanced tab and click the button to restore these settings to their defaults. Click OK three times.
• Close your web browser (if open) and open it.
• Access the web management. Open your web browser and enter the IP address of your D-Link router in the address bar. This
should open the login page for your web management.
• If you still cannot access the conguration, unplug the power to the router for 10 seconds and plug back in. Wait about 30
seconds and try accessing the conguration. If you have multiple computers, try connecting using a dierent computer.
2. What can I do if I forgot my password?
If you forgot your password, you must reset your router. Unfortunately this process will change all your settings back to the
factory defaults.
To reset the router, locate the reset button (hole) on the rear panel of the unit. With the router powered on, use a paperclip
to hold the button down for 10 seconds. Release the button and the router will go through its reboot process. Wait about 30
seconds to access the router. The default IP address is 192.168.0.1. When logging in, the username is admin and leave the
password box empty.

3. Why can’t I connect to certain sites or send and receive emails when connecting through my router?
If you are having a problem sending or receiving email, or connecting to secure sites such as eBay, banking sites, and Hotmail,
we suggest lowering the MTU in increments of ten (Ex. 1492, 1482, 1472, etc).
To nd the proper MTU Size, you’ll have to do a special ping of the destination you’re trying to go to. A destination could be
another computer, or a URL.
• Click on Start and then click Run.
• Windows® 95, 98, and Me users type in command (Windows® NT, 2000, XP, Vista®, and 7 users type in cmd) and
press Enter (or click OK).
• Once the window opens, you’ll need to do a special ping. Use the following syntax:
ping [url] [-f] [-l] [MTU value]
Example: ping yahoo.com -f -l 1472
141D-Link DIR-850L User Manual
Section 6 - Troubleshooting
You should start at 1472 and work your way down by 10 each time. Once you get a reply, go up by 2 until you get a fragmented
packet. Take that value and add 28 to the value to account for the various TCP/IP headers. For example, lets say that 1452 was the
proper value, the actual MTU size would be 1480, which is the optimum for the network we’re working with (1452+28=1480).
Once you nd your MTU, you can now congure your router with the proper MTU size.
To change the MTU rate on your router follow the steps below:
• Open your browser, enter the IP address of your router (192.168.0.1) and click OK.
• Enter your username (admin) and password (blank by default). Click OK to enter the web conguration page
for the device.
• Click on Setup and then click Manual Congure.
• To change the MTU enter the number in the MTU eld and click Save Settings to save your settings.
• Test your email. If changing the MTU does not resolve the problem, continue changing the MTU in increments
of ten.

Appendix A - Wireless Basics
D-Link wireless products are based on industry standards to provide easy-to-use and compatible high-speed wireless
connectivity within your home, business or public access wireless networks. Strictly adhering to the IEEE standard, the D-Link
wireless family of products will allow you to securely access the data you want, when and where you want it. You will be able
to enjoy the freedom that wireless networking delivers.
A wireless local area network (WLAN) is a cellular computer network that transmits and receives data with radio signals instead of
wires. Wireless LANs are used increasingly in both home and oce environments, and public areas such as airports, coee shops
and universities. Innovative ways to utilize WLAN technology are helping people to work and communicate more eciently.
Increased mobility and the absence of cabling and other xed infrastructure have proven to be benecial for many users.
Wireless users can use the same applications they use on a wired network. Wireless adapter cards used on laptop and desktop
systems support the same protocols as Ethernet adapter cards.
Under many circumstances, it may be desirable for mobile network devices to link to a conventional Ethernet LAN in order to
use servers, printers or an Internet connection supplied through the wired LAN. A Wireless Router is a device used to provide
this link.

What is Wireless?
Wireless or Wi-Fi technology is another way of connecting your computer to the network without using wires. Wi-Fi uses radio
frequency to connect wirelessly, so you have the freedom to connect computers anywhere in your home or oce network.
Why D-Link Wireless?
D-Link is the worldwide leader and award winning designer, developer, and manufacturer of networking products. D-Link
delivers the performance you need at a price you can aord. D-Link has all the products you need to build your network.
How does wireless work?
Wireless works similar to how cordless phone work, through radio signals to transmit data from one point A to point B. But
wireless technology has restrictions as to how you can access the network. You must be within the wireless network range area
to be able to connect your computer. There are two dierent types of wireless networks Wireless Local Area Network (WLAN),
and Wireless Personal Area Network (WPAN).
Wireless Local Area Network (WLAN)
In a wireless local area network, a device called an Access Point (AP) connects computers to the network. The access point has
a small antenna attached to it, which allows it to transmit data back and forth over radio signals. With an indoor access point
as seen in the picture, the signal can travel up to 300 feet. With an outdoor access point the signal can reach out up to 30 miles
to serve places like manufacturing plants, industrial locations, college and high school campuses, airports, golf courses, and
many other outdoor venues.
144D-Link DIR-850L User Manual
Appendix A - Wireless Basics
Wireless Personal Area Network (WPAN)
Bluetooth is the industry standard wireless technology used for WPAN. Bluetooth devices in WPAN operate in a range up to
30 feet away.
Compared to WLAN the speed and wireless operation range are both less than WLAN, but in return it doesn’t use nearly as
much power which makes it ideal for personal devices, such as mobile phones, PDAs, headphones, laptops, speakers, and other
devices that operate on batteries.
Who uses wireless?
Wireless technology as become so popular in recent years that almost everyone is using it, whether it’s for home, oce, business,
D-Link has a wireless solution for it.
Home
• Gives everyone at home broadband access
• Surf the web, check email, instant message, etc.
• Gets rid of the cables around the house
• Simple and easy to use
Small Oce and Home Oce
• Stay on top of everything at home as you would at oce
• Remotely access your oce network from home
• Share Internet connection and printer with multiple computers
• No need to dedicate oce space

Where is wireless used?
Wireless technology is expanding everywhere not just at home or oce. People like the freedom of mobility and it’s becoming
so popular that more and more public facilities now provide wireless access to attract people. The wireless connection in public
places is usually called “hotspots”.
Using a D-Link Cardbus Adapter with your laptop, you can access the hotspot to connect to Internet from remote locations

Wireless network is easy to setup, but if you’re installing it for the rst time it could be quite a task not knowing where to start.
That’s why we’ve put together a few setup steps and tips to help you through the process of setting up a wireless network.
Tips
Here are a few things to keep in mind, when you install a wireless network.
Centralize your router or Access Point
Make sure you place the router/access point in a centralized location within your network for the best performance. Try to
place the router/access point as high as possible in the room, so the signal gets dispersed throughout your home. If you have
a two-story home, you may need a repeater to boost the signal to extend the range.
Eliminate Interference
Place home appliances such as cordless telephones, microwaves, and televisions as far away as possible from the router/access
point. This would signicantly reduce any interference that the appliances might cause since they operate on same frequency.

Appendix A - Wireless Basics
Don’t let you next-door neighbors or intruders connect to your wireless network. Secure your wireless network by turning on
the WPA or WEP security feature on the router. Refer to product manual for detail information on how to set it up.
There are basically two modes of networking:
• Infrastructure – All wireless clients will connect to an access point or wireless router.
• Ad-Hoc – Directly connecting to another computer, for peer-to-peer communication, using wireless network
adapters on each computer, such as two or more DIR-850L wireless network Cardbus adapters.
An Infrastructure network contains an Access Point or wireless router. All the wireless devices, or clients, will connect to the
wireless router or access point.
An Ad-Hoc network contains only clients, such as laptops with wireless cardbus adapters. All the adapters must be in Ad-Hoc
mode to communicate.

Check your IP address
After you install your new D-Link adapter, by default, the TCP/IP settings should be set to obtain an IP address from a DHCP
server (i.e. wireless router) automatically. To verify your IP address, please follow the steps below.
Click on Start > Run. In the run box type cmd and click OK. (Windows® 7/Vista® users type cmd in the Start Search box.)
At the prompt, type ipcong and press Enter.
This will display the IP address, subnet mask, and the
default gateway of your adapter.
If the address is 0.0.0.0, check your adapter installation,
security settings, and the settings on your router.
Some rewall software programs may block a DHCP
request on newly installed adapters.

Appendix B - Networking Basics
Statically Assign an IP address
If you are not using a DHCP capable gateway/router, or you need to assign a static IP address, please follow the steps below:
Step 1
Windows® 7 - Click on Start > Control Panel > Network and Internet > Network and Sharing Center.
Windows Vista® - Click on Start > Control Panel > Network and Internet > Network and Sharing Center > Manage Network
Connections.
Windows® XP - Click on Start > Control Panel > Network Connections.
Windows® 2000 - From the desktop, right-click My Network Places > Properties.
Step 2
Right-click on the Local Area Connection which represents your network adapter and select Properties.
Step 3
Highlight Internet Protocol (TCP/IP) and click Properties.
Step 4
Click Use the following IP address and enter an IP address that is on the same subnet
as your network or the LAN IP address on your router.
Example: If the router´s LAN IP address is 192.168.0.1, make your IP address 192.168.0.X
where X is a number between 2 and 99. Make sure that the number you choose is not
in use on the network. Set the Default Gateway the same as the LAN IP address of your
router (I.E. 192.168.0.1).
Set Primary DNS the same as the LAN IP address of your router (192.168.0.1). The
Secondary DNS is not needed or you may enter a DNS server from your ISP.
Step 5
Click OK twice to save your settings.
