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 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-131 offers the following types of security:
• WPA2 (Wi-Fi Protected Access 2) • WPA (Wi-Fi Protected Access)
• WPA2-PSK (Pre-Shared Key)
• WPA-PSK (Pre-Shared Key)
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.

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
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?

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 USB 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, Nanowaves, 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.
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.

Appendix A - Wireless Basics
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. Unfortunately 802.11g/n products such as the DWA-131 do not support ad-hoc
mode.
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 USB Adapters. All the adapters must be in Ad-Hoc
mode to communicate.
* Not supported with the DWA-131.

Check your IP address
After you install your new D-Link wireless adapter and have established a wireless connection, by default, the TCP/IP settings
should be set to obtain an IP address from a DHCP server (i.e. router) automatically. To verify your IP address, please follow the
steps below.
Windows® XP Users
• 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.
Windows® 7/Windows Vista® Users
• Click Start > All Programs > Accessories > Command Prompt. You may need
administrative access to run this application.
• For all additional prompt windows inquiring of running the command prompt
application, select Yes, OK, or Continue.
• At the prompt, type ipconfig and press Enter.
• This will display the IP address, subnet mask, and 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.
