Wireless Installation Considerations
The D-Link wireless adapter 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 adapter 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 difference. A solid metal door or aluminum studs may have a negative effect 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 (fish tanks), mirrors, file
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 4 - Wireless Security
Wireless Security
This section will show you the different levels of security you can use to protect your data from intruders. The
DWA-552 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 defined 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 defined so that you can
change keys easily.
D-Link DWA-552 User Manual
25
Section 4 - Wireless 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 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-specific 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.

• In Ad-Hoc mode, both wireless clients will need to have the same SSID. Please note that it might
be necessary to set up one client to establish a BSS (Basic Service Set) and wait briefly before
setting up other clients. This prevents several clients from trying to establish a BSS at the same
time, which can result in multiple singular BSSs being established, rather than a single BSS with
multiple clients associated to it.
• Check that the Network Connection for the wireless client is configured properly. Select AP
(Infrastructure) when connecting to an access point and select Ad-Hoc mode when connecting
without an access point. Double-click on the WLAN icon in the taskbar > click on Configuration to
change the settings for the wireless adapter.
• If Security is enabled, make sure that the correct encryption keys are entered on both the DWA-552
and the access point. Double-click on the WLAN icon in the taskbar > click Encryption. Check
to see that the key selected is set to the same key as other devices on the network.
7. How can I troubleshoot distance issues using the DWA-552?
• Move the DWA-552 and Access Point or Wireless router into the same room and then test the
wireless connection.
• Change the channel of the Access Point.
• Move devices within the line of sight.

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 office 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 efficiently. Increased
mobility and the absence of cabling and other fixed infrastructure have proven to be beneficial 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 office 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 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.

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, office, business,
D-Link has a wireless solution for it.
Home
• Gives everyone at home broadband access
• Surf the web, check email, instant message, and etc
• Gets rid of the cables around the house
• Simple and easy to use
Small Office and Home Office
•Stay on top of everything at home as you would at office
• Remotely access your office network from home
• Share Internet connection and printer with multiple computers
• No need to dedicate office space

Where is wireless used?
Wireless technology is expanding everywhere not just at home or office. 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 wireless desktop 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 first 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 significantly reduce any interference that the appliances might cause since they operate on same frequency.

Appendix A - Wireless Basics
Security
Don’t let your 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.
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 DWA-552 wireless network wireless desktop 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 desktop 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.
At the prompt, type ipconfig 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
firewall software programs may block a DHCP request
on newly installed adapters.
If you are connecting to a wireless network at a hotspot
(e.g. hotel, coffee shop, airport), please contact an
employee or administrator to verify their wireless network settings.
