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 Cloud Gigabit Router N600 with SmartBeam™ Technology (DIR-845L) comes equipped with 4 Gigabit ports to
provide speeds up to 10x faster than standard 10/100 ports. It also uses 802.11n technology with multiple intelligent antennas
to maximize the speed and range of your wireless signal to signicantly outperform 802.11g devices.
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-845L 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.

4D-Link DIR-845L User Manual
Section 1 - Product Overview
• Faster Wireless Networking - The DIR-845L provides up to 300Mbps* wireless connection with other 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 802.11n wireless router gives you the freedom of
wireless networking at speeds 14x faster than 802.11g.
• Compatible with 802.11a/g Devices - The DIR-845L is still fully compatible with the IEEE 802.11g and 802.11a
standards, so it can connect with existing 802.11g and 802.11a 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-845L can pass through VPN sessions. It supports
multiple and concurrent IPSec and PPTP sessions, so users behind the DIR-845L can securely access
corporate networks.
• User-friendly Setup Wizard - Through its easy-to-use Web-based user interface, the DIR-845L 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 and 802.11n 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.

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.

Section 2 - Installation
Note: It is strongly recommended to replace your existing router with the DIR-845L instead of using both. If your modem is a combo
router, you may want to contact your ISP or manufacturer’s user guide to put the router into Bridge mode, which will ‘turn o’ the
router (NAT) functions.
If you are connecting the DIR-845L router to an existing router to use as a wireless access point and/or switch, you will have
to do the following to the DIR-845L before connecting it to your network:
• Disable UPnP™
• Disable DHCP
• Change the LAN IP address to an available address on your network. The LAN ports on the router cannot accept
a DHCP address from your other router.
To connect to another router, please follow the steps below:
1. Plug the power into the router. Connect one of your computers to the router (LAN port) using an Ethernet cable. Make sure
your IP address on the computer is 192.168.0.xxx (where xxx is between 2 and 254). Please see the Networking Basics
section for more information. If you need to change the settings, write down your existing settings before making any
changes. In most cases, your computer should be set to receive an IP address automatically in which case you will not have
to do anything to your computer.
2. Open a web browser, enter http://dlinkrouter.local and press Enter. When the login window appears, set the user name
to Admin and leave the password box empty. Click Log In to continue.
3. Click on Advanced and then click Advanced Network. Uncheck the Enable UPnP checkbox. Click Save Settings to continue.
4. Click Setup and then click Network Settings. Uncheck the Enable DHCP Server checkbox. Click Save Settings to continue.
Connect to an Existing Router

5. Under Router Settings, enter an available IP address and the subnet mask of your network. Click Save Settings to save your
settings. Use this new IP address to access the conguration utility of the router in the future. Close the browser and change
your computer’s IP settings back to the original values as in Step 1.
6. Disconnect the Ethernet cable from the router and reconnect your computer to your network.
7. Connect an Ethernet cable in one of the LAN ports of the router and connect it to your other router. Do not plug anything
into the Internet (WAN) port of the D-Link router.
8. You may now use the other 3 LAN ports to connect other Ethernet devices and computers. To congure your wireless network,
open a web browser and enter the IP address you assigned to the router. Refer to the Conguration and Wireless Security
sections for more information on setting up your wireless network.
