Wireless Installation Considerations
The D-Link wireless router 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 router 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 8 - Troubleshooting
Troubleshooting
This chapter provides solutions to problems that can occur during the installation and operation of the DIR-518L. Read the
following descriptions if you are having problems. The examples below are illustrated in Windows® XP. If you have a different
operating system, the screenshots on your computer will look similar to the following examples.
1. Why can’t I access the web-based configuration utility?
When entering the IP address of the D-Link router (192.168.0.1 for example), you are not connecting to a website nor do you
have to be connected to the Internet. The device has the utility built-in to a ROM chip in the device itself. Your computer must
be on the same IP subnet to connect to the web-based utility.
• Make sure you have an updated Java-enabled web browser. We recommend the following:
Microsoft Internet Explorer® 6.0 and higher
Mozilla Firefox 3.0 and higher
Google™ Chrome 2.0 and higher
Apple Safari 3.0 and higher
• Verify physical connectivity by checking for solid link lights on the device. If you do not get a solid link light, try using a
different cable or connect to a different port on the device if possible. If the computer is turned off, the link light may not be
on.
• Disable any Internet security software running on the computer. Software firewalls such as Zone Alarm, Black Ice, Sygate,
Norton Personal Firewall, and Windows® XP firewall may block access to the configuration pages. Check the help files included
with your firewall software for more information on disabling or configuring it.
D-Link DIR-518L User Manual

Section 8 - Troubleshooting
• Configure your Internet settings:
• Go to Start > Settings > Control Panel. Double-click the Internet Options Icon. From the Security tab, click
the button to restore the settings to their defaults.
• Click the Connection tab and set the dial-up option to Never Dial a Connection. Click the LAN Settings button.
Make sure nothing is checked. Click OK.
• Go to the Advanced tab and click the button to restore these settings to their defaults. Click OK three times.
• Close your web browser (if open) and open it.
• Access the web management. Open your web browser and enter the IP address of your D-Link router in the address bar. This
should open the login page for your web management.
• If you still cannot access the configuration, unplug the power to the router for 10 seconds and plug back in. Wait about 30
seconds and try accessing the configuration. If you have multiple computers, try connecting using a different computer.
2. What can I do if I forgot my password?
If you forgot your password, you must reset your router. Unfortunately this process will change all your settings back to the
factory defaults.
To reset the router, locate the reset button (hole) on the rear panel of the unit. With the router powered on, use a paperclip
to hold the button down for 10 seconds. Release the button and the router will go through its reboot process. Wait about 30
seconds to access the router. The default IP address is 192.168.0.1. When logging in, the username is admin and leave the
password box empty.

Section 8 - Troubleshooting
3. Why can’t I connect to certain sites or send and receive emails when connecting through my router?
If you are having a problem sending or receiving email, or connecting to secure sites such as eBay, banking sites, and Hotmail,
we suggest lowering the MTU in increments of ten (Ex. 1492, 1482, 1472, etc).
To find the proper MTU Size, you’ll have to do a special ping of the destination you’re trying to go to. A destination could be
another computer, or a URL.
• Click on Start and then click Run.
• Windows® 95, 98, and Me users type in command (Windows® NT, 2000, XP, Vista®, and 7 users type in cmd) and
press Enter (or click OK).
• Once the window opens, you’ll need to do a special ping. Use the following syntax:
ping [url] [-f] [-l] [MTU value]
Example: ping yahoo.com -f -l 1472
D-Link DIR-518L User Manual
33
Section 8 - Troubleshooting
You should start at 1472 and work your way down by 10 each time. Once you get a reply, go up by 2 until you get a fragmented
packet. Take that value and add 28 to the value to account for the various TCP/IP headers. For example, lets say that 1452 was the
proper value, the actual MTU size would be 1480, which is the optimum for the network we’re working with (1452+28=1480).
Once you find your MTU, you can now configure your router with the proper MTU size.
To change the MTU rate on your router follow the steps below:
• Open your browser, enter the IP address of your router (192.168.0.1) and click OK.
• Enter your username (admin) and password (blank by default). Click OK to enter the web configuration page
for the device.
• Click on Setup and then click Manual Configure.
• To change the MTU enter the number in the MTU field and click Save Settings to save your settings.
• Test your email. If changing the MTU does not resolve the problem, continue changing the MTU in increments
of ten.

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.

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, etc.
• Gets rid of the cables around the house
• Simple and easy to use
Small Office and Home Office

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 or WEP security feature on the router. Refer to product manual for detail information on how to set it up.

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® 7/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.

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 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 the Default Gateway the same as the LAN IP address of your
router (I.E. 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.

Version 3, 29 June 2007
Copyright (C) 2007 Free Software Foundation, Inc.  Everyone is permitted to copy and distribute verbatim
copies of this license document, but changing it is not allowed.
D-Link DIR-518L User Manual

Appendix D - GPL Code Statement
Preamble
The GNU General Public License is a free, copyleft license for software and other kinds of works.
The licenses for most software and other practical works are designed to take away your freedom to share and change the
works. By contrast, the GNU General Public License is intended to guarantee your freedom to share and change all versions
of a program--to make sure it remains free software for all its users. We, the Free Software Foundation, use the GNU General
Public License for most of our software; it applies also to any other work released this way by its authors. You can apply it to
your programs, too.
When we speak of free software, we are referring to freedom, not price. Our General Public Licenses are designed to make
sure that you have the freedom to distribute copies of free software (and charge for them if you wish), that you receive source
code or can get it if you want it, that you can change the software or use pieces of it in new free programs, and that you know
you can do these things.
To protect your rights, we need to prevent others from denying you these rights or asking you to surrender the rights. Therefore,
you have certain responsibilities if you distribute copies of the software, or if you modify it: responsibilities to respect the
freedom of others.
For example, if you distribute copies of such a program, whether gratis or for a fee, you must pass on to the recipients the
same freedoms that you received. You must make sure that they, too, receive or can get the source code. And you must show
them these terms so they know their rights.
Developers that use the GNU GPL protect your rights with two steps:
(1) assert copyright on the software, and (2) offer you this License giving you legal permission to copy, distribute and/or
modify it.
For the developers’ and authors’ protection, the GPL clearly explains that there is no warranty for this free software. For both
users’ and authors’ sake, the GPL requires that modified versions be marked as changed, so that their problems will not be
attributed erroneously to authors of previous versions.
Some devices are designed to deny users access to install or run modified versions of the software inside them, although
the manufacturer can do so. This is fundamentally incompatible with the aim of protecting users’ freedom to change the
software. The systematic pattern of such abuse occurs in the area of products for individuals to use, which is precisely where it
is most unacceptable. Therefore, we have designed this version of the GPL to prohibit the practice for those products. If such
problems arise substantially in other domains, we stand ready to extend this provision to those domains in future versions of
the GPL, as needed to protect the freedom of users.

Appendix D - GPL Code Statement
Finally, every program is threatened constantly by software patents. States should not allow patents to restrict development
and use of software on general-purpose computers, but in those that do, we wish to avoid the special danger that patents
applied to a free program could make it effectively proprietary. To prevent this, the GPL assures that patents cannot be used
to render the program non-free.
The precise terms and conditions for copying, distribution and modification follow.
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.
D-Link DIR-518L User Manual
43
Appendix D - GPL Code Statement
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.
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.

Appendix D - GPL Code Statement
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.
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.
D-Link DIR-518L User Manual
45
Appendix D - GPL Code Statement
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.
A compilation of a covered work with other separate and independent works, which are not by their nature extensions of
the covered work, and which are not combined with it such as to form a larger program, in or on a volume of a storage or
distribution medium, is called an “aggregate” if the compilation and its resulting copyright are not used to limit the access or
legal rights of the compilation’s users beyond what the individual works permit. Inclusion of a covered work in an aggregate
does not cause this License to apply to the other parts of the aggregate.
D-Link DIR-518L User Manual
46
Appendix D - GPL Code Statement
6. Conveying Non-Source Forms.
You may convey a covered work in object code form under the terms of sections 4 and 5, provided that you also convey the
machine-readable Corresponding Source under the terms of this License, in one of these ways:
a) Convey the object code in, or embodied in, a physical product (including a physical distribution medium),
accompanied by the Corresponding Source fixed on a durable physical medium customarily used for software
interchange.
b) Convey the object code in, or embodied in, a physical product (including a physical distribution medium),
accompanied by a written offer, valid for at least three years and valid for as long as you offer spare parts or
customer support for that product model, to give anyone who possesses the object code either (1) a copy
of the Corresponding Source for all the software in the product that is covered by this License, on a durable
physical medium customarily used for software interchange, for a price no more than your reasonable cost of
physically performing this conveying of source, or (2) access to copy the Corresponding Source from a network
server at no charge.
c) Convey individual copies of the object code with a copy of the written offer to provide the Corresponding
Source. This alternative is allowed only occasionally and noncommercially, and only if you received the object
code with such an offer, in accord with subsection 6b.
d) Convey the object code by offering access from a designated place (gratis or for a charge), and offer equivalent
access to the Corresponding Source in the same way through the same place at no further charge. You need
not require recipients to copy the Corresponding Source along with the object code. If the place to copy the
object code is a network server, the Corresponding Source may be on a different server (operated by you or
a third party) that supports equivalent copying facilities, provided you maintain clear directions next to the
object code saying where to find the Corresponding Source. Regardless of what server hosts the Corresponding
Source, you remain obligated to ensure that it is available for as long as needed to satisfy these requirements.
e) Convey the object code using peer-to-peer transmission, provided you inform other peers where the object
code and Corresponding Source of the work are being offered to the general public at no charge under
subsection 6d.
A separable portion of the object code, whose source code is excluded from the Corresponding Source as a System
Library, need not be included in conveying the object code work.
D-Link DIR-518L User Manual

Appendix D - GPL Code Statement
A “User Product” is either (1) a “consumer product”, which means any tangible personal property which is normally used for
personal, family, or household purposes, or (2) anything designed or sold for incorporation into a dwelling. In determining
whether a product is a consumer product, doubtful cases shall be resolved in favor of coverage. For a particular product
received by a particular user, “normally used” refers to a typical or common use of that class of product, regardless of the status
of the particular user or of the way in which the particular user actually uses, or expects or is expected to use, the product. A
product is a consumer product regardless of whether the product has substantial commercial, industrial or non-consumer
uses, unless such uses represent the only significant mode of use of the product.
“Installation Information” for a User Product means any methods, procedures, authorization keys, or other information required
to install and execute modified versions of a covered work in that User Product from a modified version of its Corresponding
Source. The information must suffice to ensure that the continued functioning of the modified object code is in no case
prevented or interfered with solely because modification has been made.
If you convey an object code work under this section in, or with, or specifically for use in, a User Product, and the conveying
occurs as part of a transaction in which the right of possession and use of the User Product is transferred to the recipient in
perpetuity or for a fixed term (regardless of how the transaction is characterized), the Corresponding Source conveyed under
this section must be accompanied by the Installation Information. But this requirement does not apply if neither you nor any
third party retains the ability to install modified object code on the User Product (for example, the work has been installed in
ROM).
The requirement to provide Installation Information does not include a requirement to continue to provide support service,
warranty, or updates for a work that has been modified or installed by the recipient, or for the User Product in which it has
been modified or installed. Access to a network may be denied when the modification itself materially and adversely affects
the operation of the network or violates the rules and protocols for communication across the network.
Corresponding Source conveyed, and Installation Information provided, in accord with this section must be in a format that is
publicly documented (and with an implementation available to the public in source code form), and must require no special
password or key for unpacking, reading or copying.
D-Link DIR-518L User Manual

Appendix D - GPL Code Statement
7. Additional Terms.
“Additional permissions” are terms that supplement the terms of this License by making exceptions from one or more of its
conditions. Additional permissions that are applicable to the entire Program shall be treated as though they were included in
this License, to the extent that they are valid under applicable law. If additional permissions apply only to part of the Program,
that part may be used separately under those permissions, but the entire Program remains governed by this License without
regard to the additional permissions.
When you convey a copy of a covered work, you may at your option remove any additional permissions from that copy, or
from any part of it. (Additional permissions may be written to require their own removal in certain cases when you modify
the work). You may place additional permissions on material, added by you to a covered work, for which you have or can give
appropriate copyright permission.
Notwithstanding any other provision of this License, for material you add to a covered work, you may (if authorized by the
copyright holders of that material) supplement the terms of this License with terms:
a) Disclaiming warranty or limiting liability differently from the terms of sections 15 and 16 of this License; or
b) Requiring preservation of specified reasonable legal notices or author attributions in that material or in the
Appropriate Legal Notices displayed by works containing it; or
c) Prohibiting misrepresentation of the origin of that material, or requiring that modified versions of such material
be marked in reasonable ways as different from the original version; or
d) Limiting the use for publicity purposes of names of licensors or authors of the material; or
e) Declining to grant rights under trademark law for use of some trade names, trademarks, or service marks; or
f ) Requiring indemnification of licensors and authors of that material by anyone who conveys the material (or
modified versions of it) with contractual assumptions of liability to the recipient, for any liability that these
contractual assumptions directly impose on those licensors and authors.
D-Link DIR-518L User Manual
49
Appendix D - GPL Code Statement
All other non-permissive additional terms are considered “further restrictions” within the meaning of section 10. If the Program
as you received it, or any part of it, contains a notice stating that it is governed by this License along with a term that is a
further restriction, you may remove that term. If a license document contains a further restriction but permits relicensing
or conveying under this License, you may add to a covered work material governed by the terms of that license document,
provided that the further restriction does not survive such relicensing or conveying.
If you add terms to a covered work in accord with this section, you must place, in the relevant source files, a statement of the
additional terms that apply to those files, or a notice indicating where to find the applicable terms.
Additional terms, permissive or non-permissive, may be stated in the form of a separately written license, or stated as
exceptions; the above requirements apply either way.
8. Termination.
You may not propagate or modify a covered work except as expressly provided under this License. Any attempt otherwise to
propagate or modify it is void, and will automatically terminate your rights under this License (including any patent licenses
granted under the third paragraph of section 11).
However, if you cease all violation of this License, then your license from a particular copyright holder is reinstated (a)
provisionally, unless and until the copyright holder explicitly and finally terminates your license, and (b) permanently, if the
copyright holder fails to notify you of the violation by some reasonable means prior to 60 days after the cessation.
Moreover, your license from a particular copyright holder is reinstated permanently if the copyright holder notifies you of the
violation by some reasonable means, this is the first time you have received notice of violation of this License (for any work)
from that copyright holder, and you cure the violation prior to 30 days after your receipt of the notice.
Termination of your rights under this section does not terminate the licenses of parties who have received copies or rights
D-Link DIR-518L User Manual
50
Appendix D - GPL Code Statement
from you under this License. If your rights have been terminated and not permanently reinstated, you do not qualify to
receive new licenses for the same material under section 10.
9. Acceptance Not Required for Having Copies.
You are not required to accept this License in order to receive or run a copy of the Program. Ancillary propagation of a
covered work occurring solely as a consequence of using peer-to-peer transmission to receive a copy likewise does not
require acceptance. However, nothing other than this License grants you permission to propagate or modify any covered
work. These actions infringe copyright if you do not accept this License. Therefore, by modifying or propagating a covered
work, you indicate your acceptance of this License to do so.
10. Automatic Licensing of Downstream Recipients.
Each time you convey a covered work, the recipient automatically receives a license from the original licensors, to run, modify
and propagate that work, subject to this License. You are not responsible for enforcing compliance by third parties with this
License.
An “entity transaction” is a transaction transferring control of an organization, or substantially all assets of one, or subdividing
an organization, or merging organizations. If propagation of a covered work results from an entity transaction, each party
to that transaction who receives a copy of the work also receives whatever licenses to the work the party’s predecessor in
interest had or could give under the previous paragraph, plus a right to possession of the Corresponding Source of the work
from the predecessor in interest, if the predecessor has it or can get it with reasonable efforts.
You may not impose any further restrictions on the exercise of the rights granted or affirmed under this License. For example,
you may not impose a license fee, royalty, or other charge for exercise of rights granted under this License, and you may not
initiate litigation (including a cross-claim or counterclaim in a lawsuit) alleging that any patent claim is infringed by making,
using, selling, offering for sale, or importing the Program or any portion of it.
D-Link DIR-518L User Manual
51
Appendix D - GPL Code Statement
11. Patents.
A “contributor” is a copyright holder who authorizes use under this License of the Program or a work on which the Program is
based. The work thus licensed is called the contributor’s “contributor version”.
A contributor’s “essential patent claims” are all patent claims owned or controlled by the contributor, whether already acquired
or hereafter acquired, that would be infringed by some manner, permitted by this License, of making, using, or selling its
contributor version, but do not include claims that would be infringed only as a consequence of further modification of
the contributor version. For purposes of this definition, “control” includes the right to grant patent sublicenses in a manner
consistent with the requirements of this License.
Each contributor grants you a non-exclusive, worldwide, royalty-free patent license under the contributor’s essential patent
claims, to make, use, sell, offer for sale, import and otherwise run, modify and propagate the contents of its contributor version.
In the following three paragraphs, a “patent license” is any express agreement or commitment, however denominated, not
to enforce a patent (such as an express permission to practice a patent or covenant not to sue for patent infringement). To
“grant” such a patent license to a party means to make such an agreement or commitment not to enforce a patent against the
party.
If you convey a covered work, knowingly relying on a patent license, and the Corresponding Source of the work is not available
for anyone to copy, free of charge and under the terms of this License, through a publicly available network server or other
readily accessible means, then you must either (1) cause the Corresponding Source to be so available, or (2) arrange to deprive
yourself of the benefit of the patent license for this particular work, or (3) arrange, in a manner consistent with the requirements
of this License, to extend the patent license to downstream recipients. “Knowingly relying” means you have actual knowledge
that, but for the patent license, your conveying the covered work in a country, or your recipient’s use of the covered work in a
country, would infringe one or more identifiable patents in that country that you have reason to believe are valid.
If, pursuant to or in connection with a single transaction or arrangement, you convey, or propagate by procuring conveyance
of, a covered work, and grant a patent license to some of the parties receiving the covered work authorizing them to use,
propagate, modify or convey a specific copy of the covered work, then the patent license you grant is automatically extended
to all recipients of the covered work and works based on it.

Appendix D - GPL Code Statement
A patent license is “discriminatory” if it does not include within the scope of its coverage, prohibits the exercise of, or is
conditioned on the non-exercise of one or more of the rights that are specifically granted under this License. You may not
convey a covered work if you are a party to an arrangement with a third party that is in the business of distributing software,
under which you make payment to the third party based on the extent of your activity of conveying the work, and under which
the third party grants, to any of the parties who would receive the covered work from you, a discriminatory patent license (a)
in connection with copies of the covered work conveyed by you (or copies made from those copies), or (b) primarily for and in
connection with specific products or compilations that contain the covered work, unless you entered into that arrangement,
or that patent license was granted, prior to 28 March 2007.
Nothing in this License shall be construed as excluding or limiting any implied license or other defenses to infringement that
may otherwise be available to you under applicable patent law.
12. No Surrender of Others’ Freedom.
If conditions are imposed on you (whether by court order, agreement or otherwise) that contradict the conditions of this
License, they do not excuse you from the conditions of this License. If you cannot convey a covered work so as to satisfy
simultaneously your obligations under this License and any other pertinent obligations, then as a consequence you may not
convey it at all. For example, if you agree to terms that obligate you to collect a royalty for further conveying from those to
whom you convey the Program, the only way you could satisfy both those terms and this License would be to refrain entirely
from conveying the Program.
13. Use with the GNU Affero General Public License.
Notwithstanding any other provision of this License, you have permission to link or combine any covered work with a work
licensed under version 3 of the GNU Affero General Public License into a single combined work, and to convey the resulting
work. The terms of this License will continue to apply to the part which is the covered work, but the special requirements of
the GNU Affero General Public License, section 13, concerning interaction through a network will apply to the combination
as such.

14. Revised Versions of this License.
The Free Software Foundation may publish revised and/or new versions of the GNU General Public License from time to time.
Such new versions will be similar in spirit to the present version, but may differ in detail to address new problems or concerns.
Each version is given a distinguishing version number. If the Program specifies that a certain numbered version of the GNU
General Public License “or any later version” applies to it, you have the option of following the terms and conditions either of
that numbered version or of any later version published by the Free Software Foundation. If the Program does not specify
a version number of the GNU General Public License, you may choose any version ever published by the Free Software
Foundation. If the Program specifies that a proxy can decide which future versions of the GNU General Public License can
be used, that proxy’s public statement of acceptance of a version permanently authorizes you to choose that version for the
Program.
Later license versions may give you additional or different permissions. However, no additional obligations are imposed on
any author or copyright holder as a result of your choosing to follow a later version.
15. Disclaimer of Warranty.
THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN OTHERWISE
STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM“AS IS”WITHOUT WARRANTY OF
ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY
AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS
WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, REPAIR OR
CORRECTION.
16. Limitation of Liability.
IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING WILL ANY COPYRIGHT HOLDER, OR ANY
OTHER PARTY WHO MODIFIES AND/OR CONVEYS THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO
USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES
SUSTAINED BY YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS), EVEN IF
SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.

17. Interpretation of Sections 15 and 16.
If the disclaimer of warranty and limitation of liability provided above cannot be given local legal effect according to their
terms, reviewing courts shall apply local law that most closely approximates an absolute waiver of all civil liability in connection
with the Program, unless a warranty or assumption of liability accompanies a copy of the Program in return for a fee.
