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, 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.
Security 
  
Don’t  let  you  next-door  neighbors  or  intruders  connect  to  your  wireless  network.  Secure  your  wireless  network  by  turning  on  the WPA  security 
feature on the router. Refer to product manual for detail information on how to set it up.

Appendix A - Wireless Basics
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 DIR-655 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. (Windows Vista® users type cmd 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. 
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® 7 - Click on Start > Control Panel > Network and Internet > Network and Sharing Center.
Windows Vista® - Click on Start > Control Panel > Network and Internet > Network and Sharing Center > Manage Network Connections.
Windows® XP - Click on Start > Control Panel > Network Connections.
Windows® 2000 - 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 192.168.0.1, make your IP address 192.168.0.X where X is a 
number between 2 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 (192.168.0.1). 
Set Primary DNS the same as the LAN IP address of your router (192.168.0.1). 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.

Appendix E - GNU General Public License
TERMS AND CONDITIONS
0. Definitions.
"This License" refers to version 3 of the GNU General Public License.
"Copyright" also means copyright-like laws that apply to other kinds of works, such as semiconductor masks.
"The Program" refers to any copyrightable work licensed under this License.  Each licensee is addressed as "you".  "Licensees" and "recipients" may 
be individuals or organizations.
To "modify" a work means to copy from or adapt all or part of the work in a fashion requiring copyright permission, other than the making of an 
exact copy.  The resulting work is called a "modified version" of the earlier work or a work "based on" the earlier work.
A "covered work" means either the unmodified Program or a work based on the Program.
To "propagate" a work means to do anything with it that, without permission, would make you directly or secondarily liable for infringement under 
applicable copyright law, except executing it on a computer or modifying a private copy.  Propagation includes copying, distribution (with or without 
modification), making available to the public, and in some countries other activities as well.
To "convey" a work means any kind of propagation that enables other parties to make or receive copies.  Mere interaction with a user through a 
computer network, with no transfer of a copy, is not conveying. 
An interactive user interface displays "Appropriate Legal Notices" to the extent that it includes a convenient and prominently visible feature that 
(1) displays an appropriate copyright notice, and (2) tells the user that there is no warranty for the work (except to the extent that warranties are 
provided), that licensees may convey the work under this License, and how to view a copy of this License.  If the interface presents a list of user 
commands or options, such as a menu, a prominent item in the list meets this criterion.
1. Source Code.
The "source code" for a work means the preferred form of the work for making modifications to it.  "Object code" means any non-source form of a 
work.
A "Standard Interface" means an interface that either is an official standard defined by a recognized standards body, or, in the case of interfaces 
specified for a particular programming language, one that is widely used among developers working in that language.  
						

							115D-Link DIR-655 User Manual
Appendix E - GNU General Public License
The "System Libraries" of an executable work include anything, other than the work as a whole, that (a) is included in the normal form of packaging 
a Major Component, but which is not part of that Major Component, and (b) serves only to enable use of the work with that Major Component, 
or to implement a Standard Interface for which an implementation is available to the public in source code form.  A "Major Component", in this 
context, means a major essential component (kernel, window system, and so on) of the specific operating system (if any) on which the executable 
work runs, or a compiler used to produce the work, or an object code interpreter used to run it.
The "Corresponding Source" for a work in object code form means all the source code needed to generate, install, and (for an executable work) 
run the object code and to modify the work, including scripts to control those activities.  However, it does not include the work's System Libraries, 
or general-purpose tools or generally available free programs which are used unmodified in performing those activities but which are not part of 
the work.  For example, Corresponding Source includes interface definition files associated with source files for the work, and the source code for 
shared libraries and dynamically linked subprograms that the work is specifically designed to require, such as by intimate data communication or 
control flow between those subprograms and other parts of the work.
The Corresponding Source need not include anything that users can regenerate automatically from other parts of the Corresponding Source.
The Corresponding Source for a work in source code form is that same work.
2. Basic Permissions.
All rights granted under this License are granted for the term of copyright on the Program, and are irrevocable provided the stated conditions are 
met.  This License explicitly affirms your unlimited permission to run the unmodified Program.  The output from running a covered work is covered 
by this License only if the output, given its content, constitutes a covered work.  This License acknowledges your rights of fair use or other equivalent, 
as provided by copyright law.
  You may make, run and propagate covered works that you do not convey, without conditions so long as your license otherwise remains in force.  
You may convey covered works to others for the sole purpose of having them make modifications exclusively for you, or provide you with facilities 
for running those works, provided that you comply with the terms of this License in conveying all material for which you do not control copyright.  
Those thus making or running the covered works for you must do so exclusively on your behalf, under your direction and control, on terms that 
prohibit them from making any copies of your copyrighted material outside their relationship with you.
Conveying under any other circumstances is permitted solely under the conditions stated below.  Sublicensing is not allowed; section 10 makes it 
unnecessary.

Appendix E - GNU General Public License
3. Protecting Users' Legal Rights From Anti-Circumvention Law.
No covered work shall be deemed part of an effective technological measure under any applicable law fulfilling obligations under article 11 of the 
WIPO copyright treaty adopted on 20 December 1996, or similar laws prohibiting or restricting circumvention of such measures.
When you convey a covered work, you waive any legal power to forbid circumvention of technological measures to the extent such circumvention is 
effected by exercising rights under this License with respect to the covered work, and you disclaim any intention to limit operation or modification 
of the work as a means of enforcing, against the work's users, your or third parties' legal rights to forbid circumvention of technological measures.
4. Conveying Verbatim Copies.
You may convey verbatim copies of the Program's source code as you receive it, in any medium, provided that you conspicuously and appropriately 
publish  on  each  copy  an  appropriate  copyright  notice;  keep  intact  all  notices  stating  that  this  License  and  any  non-permissive  terms  added  in 
accord with section 7 apply to the code; keep intact all notices of the absence of any warranty; and give all recipients a copy of this License along 
with the Program.
You may charge any price or no price for each copy that you convey, and you may offer support or warranty protection for a fee.
5. Conveying Modified Source Versions.
You may convey a work based on the Program, or the modifications to produce it from the Program, in the form of source code under the terms of 
section 4, provided that you also meet all of these conditions:
a) The work must carry prominent notices stating that you modified it, and giving a relevant date.
b) The work must carry prominent notices stating that it is released under this License and any conditions added under section 7.  
This requirement modifies the requirement in section 4 to "keep intact all notices".
c) You must license the entire work, as a whole, under this License to anyone who comes into possession of a copy.  This License 
will therefore apply, along with any applicable section 7 additional terms, to the whole of the work, and all its parts, regardless 
of how they are packaged.  This License gives no permission to license the work in any other way, but it does not invalidate such 
permission if you have separately received it.
d) If the work has interactive user interfaces, each must display Appropriate Legal Notices; however, if the Program has interactive 
interfaces that do not display Appropriate Legal Notices, your work need not make them do so.
