Section 1 - Product Overview
Introduction
DIR-456U allows users to access worldwide mobile broadband networks. Once connected, users can transfer data,
stream media, send SMS messages, and make mobile phone calls. Simply insert your UMTS/HSUPA SIM card,
and share your 3.5G Internet connection through a secure 802.11n wireless network or using any of the four 10/100
Ethernet ports.
While accessing your 3.5G Internet connection, you will still have the ability to answer incoming mobile calls and
respond to SMS messages. An RJ-11 jack allows you to attach a standard analog phone for high-quality mobile
calls over a GSM network. Enjoy the comfort and convenience of your favorite ofce phone anywhere you go.
Keep your wireless network safe with WPA/WPA2 wireless encryption. The DIR-456U utilizes dual-active rewalls
(SPI and NAT) to prevent potential attacks across the Internet.
DIR-456U can be installed quickly and easily almost anywhere. This router is great for situations where an impromptu
wireless network must be set up, or wherever conventional network access is unavailable. The DIR-456U can even
be installed in buses, trains, or boats, allowing passengers to check e-mail or chat online while commuting.

Section 2 - Installation
Connect to Your Network
Installation
This section will guide 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 an attic or garage.
Note: Ensure that your DIR-456U Mobile Router is disconnected and powered off before performing the installation steps below.
1. Insert a standard (U)SIM card into the SIM card slot on the back of the router with the gold contacts facing downwards.
2. Insert your Internet/WAN network cable into the INTERNET port on the back of the router.
Note: The 3.5G connection can also be used as a backup WAN. Once a backup is congured, the router will automatically use 3.5G
for the Internet connection if the Ethernet WAN is not available.
3. Insert the Ethernet cable into the LAN Port 1 on the back panel of the DIR-456U Mobile Router, and an available Ethernet port on the
network adapter in the computer you will use to congure the unit.
Note: The DIR-456U Mobile Router LAN Ports are “Auto-MDI/MDIX.” Therefore, patch or crossover Ethernet cables can be used.
4. Connect the power adapter to the socket on the back panel of your DIR-456U Mobile Router. Plug the other end of the power adapter
into a wall outlet or power strip.
a. The Status LED will light up to indicate that power has been supplied to the router.
b. The LEDs on the front panel will ash on and off as the DIR-456U Mobile Router performs initialization and Internet connection
processes.
c. After a few moments, if a connection has been established, the following LEDs will turn solid green: Power, Status, WAN, WLAN,
and LAN Port 1 (or whichever port(s) your Ethernet cable has been connected to).
Caution! Always unplug/power down the router before installing or removing the SIM card. Never insert or remove the SIM card while
the router is in use.

Section 2 - Installation
Connect a Telephone
A standard RJ-11 jack on the back of the router allows you to connect a standard analog telephone for voice calls.
Simply plug the phone cable into the jack labeled FXS.
You can then use your handset to dial out as you typically would with a standard landline.
Your attached phone will also ring for any incoming voice calls.

Section 2 - Installation
Wireless Installation Considerations
The DIR-456U can be accessed using a wireless connection from virtually anywhere within the operating range of your wireless network.
Keep in mind, however, that the quantity, thickness and location of walls, ceilings, or other objects that the wireless signals must pass
through, may limit the range. Ranges vary depending on the types of materials and background RF (radio frequency) noise in your home
or ofce. The key to maximizing the wireless range is to follow these basic guidelines:
1. Minimize the number of walls and ceilings between the D-Link router and other network devices. Each wall or ceiling can
reduce your adapter’s range from 3 to 90 feet (1 to 30 meters).
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. Try to position access points, wireless routers, and computers so that the signal passes through open doorways and
drywall. Materials such as glass, metal, brick, insulation, concrete and water can affect wireless performance. Large
objects such as sh tanks, mirrors, le cabinets, metal doors and aluminum studs may also have a negative effect on
range.
4. If you are using 2.4GHz cordless phones, make sure that the 2.4GHz phone base is as far away from your wireless device
as possible. The base transmits a signal even if the phone in not in use. In some cases, cordless phones, X-10 wireless
devices, and electronic equipment such as ceiling fans, uorescent lights, and home security systems may dramatically
degrade wireless connectivity.

This section will show you how to congure your new D-Link mobile router using the web-based conguration utility.
Web-based Configuration Utility
To access the conguration utility, open a web-browser such
as Internet Explorer and enter the IP address of the router
(192.168.0.1).
Type Admin and then enter the password. By default, the
password is blank.
If you get a Page Cannot be Displayed error, please refer to
the Troubleshooting section for assistance.

The setup wizard guides you through the initial setup of your router.
There are two ways to setup your Internet connection. You can use the
Web-based Internet Connection Setup Wizard or you can manually
congure using the Manual Internet Connection Setup wizard.
Click Internet Connection Setup Wizard to begin.
If you want to enter your settings without running the wizard, click
Manual Internet Connection Setup and skip to page 14.
This wizard will guide you through a step-by-step process to congure
your D-Link router to connect to the Internet.

contact your Internet Service Provider (ISP).
Click Prev to go back to the previous page or click Cancel to close the wizard.
Note: The DIR-456U supports several kinds of WAN interfaces, allowing you to
assign either a WAN or a WWAN(3.5G) connection as the Backup WAN. If the
Primary WAN is down or unavailable, congure the Backup WAN to Enable, and all
the trafc will be routed through Backup WAN. This feature is called WAN Failover.
You can use WAN Failover if you need redundancy to your Internet connection or
any other network.

Choose this option if your Internet connection uses an IP address that does not change. Your ISP generally
will provide you with this information. See page 16 for information about how to congure this type of
connection.
Choose this if your Internet connection automatically provides you with an IP Address. Most cable modems
use this type of connection. See page 17 for information about how to congure this type of connection.
Choose this option if your Internet connection requires a username and password to connect. Most DSL modems
use this style of connection. See page 18 for information about how to congure this type of connection.
Choose this option if your Internet connection requires Point-to-Point Tunneling Protocol (PPTP). See page
19 for information about how to congure this type of connection.
Choose this option if your Internet connection requires Layer 2 Tunneling Protocol (L2TP). See page 21 for
information about how to congure this type of connection.
To congure a Russian PPTP Internet connection, congure as previously described for PPTP connections.
See page 21 for information about how to congure this type of connection.
Some PPPoE connections use a static IP route to the ISP in addition to the global IP settings for the connection.
This requires an added step to dene IP settings for the physical WAN port. To congure a Russian PPPoE
Internet connection, congure as previously described for PPPoE connections and add the physical WAN
IP settings as instructed by your ISP. See page 23 for information about how to congure this type of
connection.
Select this option if you do not need to congure 3G.
