Section 2 - Installation
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.
Connect to Your Network
Note: Ensure that your DIR-455U 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 3.75G
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-455U Mobile Router, and an available Ethernet port on the
network adapter in the computer you will use to congure the unit.
Note: The DIR-455U 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-455U 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-455U 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 PHONE.
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-455U 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.

VPN tunnel with remote VPN
gateways. You can also choose
“Passthrough” to let local PCs
establish VPN tunnel with remote
VPN gateways.
Computers running Microsoft Windows can communicate with other computer by using NetBIOS. Users can
access remote network resources by browsing the My Network Places.
Computers running Microsoft Windows can communicate with other computer by using SSDP. The device will
send SSDP data to the remote IPSec network if this option is enabled.
Since VPN function requires signication processing power for encryption, too many concurrent VPN tunnels
will greatly degrade the performance of the network. This value indicates the maximum number of VPN tunnels
can be established at the same time.

Section 4 - Security
Wireless Security
This section will show you the different levels of security you can use to protect your data from intruders. The
DIR-455U offers 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)
• WEP (Wired Equivalent Privacy)
What is WEP?
WEP stands for Wired Equivalent Privacy. It is based on the IEEE 802.11 standard and uses the RC4 encryption algorithm. WEP provides
security by encrypting data over your wireless network so that it is protected as it is transmitted from one wireless device to another.
To gain access to a WEP network, you must know the key. The key is a string of characters that you create. When using WEP, you must
determine the level of encryption. The type of encryption determines the key length. 128-bit encryption requires a longer key than 64-bit
encryption. Keys are dened by entering in a string in HEX (hexadecimal - using characters 0-9, A-F) or ASCII (American Standard Code for
Information Interchange – alphanumeric characters) format. ASCII format is provided so you can enter a string that is easier to remember.
The ASCII string is converted to HEX for use over the network. Four keys can be dened so that you can change keys easily.

Section 4 - Security
Configure WEP
It is recommended to enable encryption on your wireless router before your wireless network adapters. Please establish wireless connectivity
before enabling encryption. Your wireless signal may degrade when enabling encryption due to the added overhead.
1. Log into the web-based conguration by opening a web browser and entering the IP address of the router (192.168.0.1). Click on
Wireless Settings on the left side.
2. Next to Security Mode, select Enable WEP Security.
3. Next to Authentication, select Open or Shared Key.
4. Select either 64-bit or 128-bit encryption from the drop-down box next
to WEP Encryption.
5. Next to Key Type, select either Hex or ASCII.
Hex (recommended) - Letters A-F and numbers 0-9 are valid.
ASCII - All numbers and letters are valid.
6. Next to Key 1, enter a WEP key that you create. Make sure you enter
this key exactly on all your wireless devices. You may enter up to 4
different keys.
7. Click Save Settings to save your settings. If you are conguring the router with a wireless adapter, you will lose connectivity until you
enable WEP on your adapter and enter the same WEP key as you did on the router.
67D-Link DIR-455U User Manual
Section 4 - Security
What is WPA?
WPA, or 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-specic MAC address, which is relatively simple
to be sniffed 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.

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 ofce environments, and public areas such as airports, coffee shops and universities.
Innovative ways to utilize WLAN technology are helping people to work and communicate more efciently. Increased mobility and the
absence of cabling and other xed infrastructure have proven to be benecial 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 ofce network.
Why D-Link Wireless?
D-Link is the worldwide leader and award winnin g des igner, develo per, an d man ufacturer of networking prod ucts.
D-Link delivers the performance you need at a price you can afford. 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 different 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.
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.
82D-Link DIR-455U User Manual
Appendix A - Wireless Basics
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, ofce, business, D-Link
has a wireless solution for it.
Home
• Gives everyone at home broadband access
• Surf the web, check e-mail, instant message, and etc
• Gets rid of the cables around the house
• Simple and easy to use
Small Ofce and Home Ofce
• Stay on top of everything at home as you would at ofce
• Remotely access your ofce network from home
• Share Internet connection and printer with multiple computers
• No need to dedicate ofce space

Where is wireless used?
Wireless technology is expanding everywhere not just at home or ofce. 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 like Airports,
Hotels, Coffee Shops, Libraries, Restaurants, and Convention Centers.
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 signicantly reduce any interference that the appliances might cause since they operate on same frequency.
Security
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.
84D-Link DIR-455U User Manual

Wireless Modes
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 WNA-2330 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.
