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 Per\
sonal 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.
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 batteri\
es.
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.

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  Cardbus  Adapter  with  your  laptop,  you  can  access  the  hotspot  to  connect  to  Internet  from 
remote locations like: Airports, Hotels, Coffee Shops, Libraries, Restau\
rants, 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 netwo\
rk.
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.

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.
There are basically two modes of networking: • 
Infrastructure – All wireless clients will connect to an access point or wireless r\
outer.
• 
Ad-Hoc – Directly connecting to another computer, for peer-to-peer communication, using wireless network 
adapters on each computer, such as two or more DIR-615 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.

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.

Statically Assign an IP address
If you are not using a DHCP capable gateway/router, or you need to assign a static IP address, please follow the steps 
below:
Step 1
Windows® XP - Click on Start > Control Panel > Network Connections.
Windows® 000 - From the desktop, right-click My Network Places > Properties.
Step 2
Right-click on the Local Area Connection which represents your D-Link network adapter and select Properties.
Step 3
Highlight Internet Protocol (TCP/IP) and click Properties.
Step 4
Click Use the following IP address and enter an IP address that is on the same subnet as your network or the LAN 
IP address on your router. 
Example:  If  the  router´s  LAN  IP  address  is  19.168.0.1,  make  your  IP  address 
19.168.0.X where X is a number between   and 99. Make sure that the number 
you choose is not in use on the network. Set Default Gateway the same as the LAN 
IP address of your router (19.168.0.1). 
Set Primary DNS the same as the LAN IP address of your router (19 .168.0.1). The 
Secondary DNS is not needed or you may enter a DNS server from your ISP.\
Step 5
Click OK twice to save your settings.
