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 similarly to how cordless phones work; through radio signals transmitting data from point A to point B.
However, 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, 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 with a
range of up to 30 feet.
The speed and wireless operation range of Bluetooth are both less than those of 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.

Where is wireless used?
Wireless technology is expanding everywhere not just at home or in the office. People like the freedom of mobility
and its popularity means that more and more public facilities now provide wireless access to attract people. The
wireless connection points in public places are usually called “hotspots”.
Using a D-Link USB Adapter with your laptop, you can access the hotspot to connect to Internet from remote locations
such as 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 and 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 will significantly reduce any interference that appliances operating on the same frequency
might cause.
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 the product manual for detailed information on
how to set it up.

Appendix A - Wireless Basics
There are two basic 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 DWM-140 wireless network USB 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.

Check your IP address
After you install your 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.
(Windows Vista
®
users type
in the
Start Search
box.)
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.
