that allows you to configure the wireless router using your web browser on your  
computer.  
Note: For details on configuring your wireless router using the web GUI, refer to Chapter 4:  
Configuring via the web GUI.  
You can set up the wireless router in any of these three operation modes: Router  
(IP Sharing), Repeater, and Access Point (AP). Set up the wireless router in the  
Router (IP Sharing) and Repeater modes via the Quick Internet Setup (QIS), and  
the AP mode via the web GUI.  
Note: To set up the wireless router in the AP mode, use Device Discovery included in the  
support CD to access the web GUI.  
Using the Quick Internet Setup (QIS)

network clients  
Accessing the wireless router  
Setting an IP address for wired or wireless clients  
To access the ASUS Wireless Router, you must have the correct TCP/IP settings  
on your wired or wireless clients. Ensure that the clients’ IP addresses are within  
the same subnet as the ASUS Wireless Router.  
By default, the ASUS Wireless Router integrates the DHCP server function, which  
automatically assigns IP addresses to the clients in your network.  
But in some instances, you may want to manually assign static IP addresses on  
some of the clients or computers in your network rather than automatically getting  
IP addresses from your wireless router.  
Follow the instructions below that correspond to the operating system installed on  
your client or computer.  
Note: In the Router mode, if you want to manually assign an IP address to your client, we  
recommend that you use the following settings:  
IP address: 19ꢀ.168.1.xxx (xxx can be any number between ꢀ and ꢀꢁ4. Ensure that the IP  
address is not used by another device)  
Subnet Mask: ꢀꢁꢁ.ꢀꢁꢁ.ꢀꢁꢁ.0 (same as the ASUS Wireless Router)  
Gateway: 19ꢀ.168.1.1 (IP address of the ASUS Wireless Router)  
DNS: 19ꢀ.168.1.1 (ASUS Wireless Router) or assign a known DNS server in your network

the cable and try again.  
When ADSL Modem “Link”  
light is ON (not blinking), this  
means Internet Access is  
possible.  
Restart your computer.  
Refer to the Quick Start Guide of the  
wireless router and re-configure the settings.  
Check if the WAN LED on the wireless  
router is ON.  
Check the wireless encryption settings.  
Check if the computer can get the IP  
address (via both wired network and  
wireless network).  
Ensure that your web browser is configured  
to use the local LAN, and is not configured  
to use a proxy server.  
If the ADSL “LINK” light blinks  
continuously or stays off,  
Internet access is not possible  
- the Router is unable to  
establish a connection with  
the ADSL network.  
Ensure that all your cables are all properly  
connected .  
Disconnect the power cord from the ADSL  
or cable modem, wait a few minutes, then  
reconnect the cord.  
If the ADSL light continues to blink or stays  
OFF, contact your ADSL service provider.  
Network name or encryption  
keys are forgotten.  
Try setting up the wired connection and  
configuring the wireless encryption again.  
Press the Restore button at the rear panel  
of the wireless router for more than five  
seconds.

ASUS DDNS Service  
RT-N1ꢀ B1 supports the ASUS DDNS service. When exchanging devices at the  
service center, if you have registered the ASUS DDNS service and want to keep  
the original domain name, data transfer is a must. Visit your local service center for  
more information.  
Notes:  
• If there is no activity in the domain - such as reconfiguring the router or accessing the  
registered domain name - within 90 days, the system automatically deletes the registered  
information.  
• If you encounter any problem or difficulty in using your device, contact the service center.  
Frequently Asked Questions (FAQs)  
1. Will the registered information be lost or registered by others?  
If you have not updated the registered information in 90 days, the system  
automatically deletes the registered information and the domain name may be  
registered by others.  
2. I did not register the ASUS DDNS for the router I bought six months ago.  
Can I still register it?  
Yes, you can still register the ASUS DDNS service for your router. The DDNS  
service is embedded in your router, so you can register the ASUS DDNS  
service anytime. Before registering, click Query to check if the hostname has  
been registered or not. If not, the system registers the hostname automatically.  
3. I have registered a domain name before and it has been working well until  
my friends told me that they could not access my domain name.  
Check the following:  
1. The internet is working well.  
ꢀ. The DNS server is working well.  
3. The last time you updated the domain name.  
If there are still problems in accessing your domain name, contact the service  
center.  
4. Can I register two domain names to separately access my http and ftp  
servers?  
No, you cannot. You can only register one domain name for one router. Use  
port mapping to implement security in the network.

RT-N1ꢀ B1  
41  
5. After restarting the router, why is it that I see different WAN IPs in MS  
DOS and in the router configuration page?  
This is normal. The interval time between the ISP DNS server and ASUS  
DDNS results in different WAN IPs in MS DOS and in the router configuration  
page. Different ISPs may have different interval time for IP updating.  
6. Is the ASUS DDNS service free, or is it just a trial version?  
The ASUS DDNS service is a free and embedded service in some ASUS  
routers. Check your ASUS router if it supports the ASUS DDNS service.

GNU GENERAL PUBLIC LICENSE  
Version ꢀ, June 1991  
Copyright (C) 1989, 1991 Free Software Foundation, Inc.  
ꢁ9 Temple Place, Suite 330, Boston, MA 0ꢀ111-1307 USA  
Everyone is permitted to copy and distribute verbatim copies of this license  
document, but changing it is not allowed.  
Preamble  
The licenses for most software are designed to take away your freedom to  
share and change it. By contrast, the GNU General Public License is intended  
to guarantee your freedom to share and change free software--to make sure the  
software is free for all its users. This General Public License applies to most of the  
Free Software Foundation’s software and to any other program whose authors  
commit to using it. (Some other Free Software Foundation software is covered  
by the GNU Library General Public License instead.) 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 this service 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 make restrictions that forbid anyone to deny  
you these rights or to ask you to surrender the rights. These restrictions translate  
to certain responsibilities for you if you distribute copies of the software, or if you  
modify it.  
For example, if you distribute copies of such a program, whether gratis or for a  
fee, you must give the recipients all the rights that you have. 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.  
We protect your rights with two steps: (1) copyright the software, and (ꢀ) offer you  
this license which gives you legal permission to copy, distribute and/or modify the  
software.  
RT-N1ꢀ B1  
Appendices  
46  
Also, for each author’s protection and ours, we want to make certain that everyone  
understands that there is no warranty for this free software. If the software is  
modified by someone else and passed on, we want its recipients to know that what  
they have is not the original, so that any problems introduced by others will not  
reflect on the original authors’ reputations.  
Finally, any free program is threatened constantly by software patents. We wish to  
avoid the danger that redistributors of a free program will individually obtain patent  
licenses, in effect making the program proprietary. To prevent this, we have made it  
clear that any patent must be licensed for everyone’s free use or not licensed at all.  
The precise terms and conditions for copying, distribution and modification follow.  
Terms & conditions for copying, distribution, & modification  
0. This License applies to any program or other work which contains a notice  
placed by the copyright holder saying it may be distributed under the terms of  
this General Public License. The “Program”, below, refers to any such program  
or work, and a “work based on the Program” means either the Program or  
any derivative work under copyright law: that is to say, a work containing  
the Program or a portion of it, either verbatim or with modifications and/or  
translated into another language. (Hereinafter, translation is included without  
limitation in the term “modification”.) Each licensee is addressed as “you”.  
Activities other than copying, distribution and modification are not covered  
by this License; they are outside its scope. The act of running the Program is  
not restricted, and the output from the Program is covered only if its contents  
constitute a work based on the Program (independent of having been made by  
running the Program). Whether that is true depends on what the Program does.  
1. You may copy and distribute 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 and  
disclaimer of warranty; keep intact all the notices that refer to this License and  
to the absence of any warranty; and give any other recipients of the Program a  
copy of this License along with the Program.  
You may charge a fee for the physical act of transferring a copy, and you may  
at your option offer warranty protection in exchange for a fee.  
ꢀ. You may modify your copy or copies of the Program or any portion of it,  
thus forming a work based on the Program, and copy and distribute such  
modifications or work under the terms of Section 1 above, provided that you  
also meet all of these conditions:  
a) You must cause the modified files to carry prominent notices stating that  
you changed the files and the date of any change.  
b) You must cause any work that you distribute or publish, that in whole or in  
part contains or is derived from the Program or any part thereof, to be licensed  
as a whole at no charge to all third parties under the terms of this License.  
c) If the modified program normally reads commands interactively when run,  
Appendices  
RT-N1ꢀ B1  
47  
you must cause it, when started running for such interactive use in the most  
ordinary way, to print or display an announcement including an appropriate  
copyright notice and a notice that there is no warranty (or else, saying that  
you provide a warranty) and that users may redistribute the program under  
these conditions, and telling the user how to view a copy of this License.  
(Exception: if the Program itself is interactive but does not normally print such  
an announcement, your work based on the Program is not required to print an  
announcement.)  
These requirements apply to the modified work as a whole. If identifiable  
sections of that work are not derived from the Program, and can be reasonably  
considered independent and separate works in themselves, then this License,  
and its terms, do not apply to those sections when you distribute them as  
separate works. But when you distribute the same sections as part of a whole  
which is a work based on the Program, the distribution of the whole must be on  
the terms of this License, whose permissions for other licensees extend to the  
entire whole, and thus to each and every part regardless of who wrote it.  
Thus, it is not the intent of this section to claim rights or contest your rights to  
work written entirely by you; rather, the intent is to exercise the right to control  
the distribution of derivative or collective works based on the Program.  
In addition, mere aggregation of another work not based on the Program with  
the Program (or with a work based on the Program) on a volume of a storage  
or distribution medium does not bring the other work under the scope of this  
License.  
3. You may copy and distribute the Program (or a work based on it, under Section  
ꢀ) in object code or executable form under the terms of Sections 1 and ꢀ above  
provided that you also do one of the following:  
a) Accompany it with the complete corresponding machine-readable source  
code, which must be distributed under the terms of Sections 1 and ꢀ above on  
a medium customarily used for software interchange; or,  
b) Accompany it with a written offer, valid for at least three years, to give any  
third party, for a charge no more than your cost of physically performing source  
distribution, a complete machine-readable copy of the corresponding source  
code, to be distributed under the terms of Sections 1 and ꢀ above on a medium  
customarily used for software interchange; or,  
c) Accompany it with the information you received as to the offer to distribute  
corresponding source code. (This alternative is allowed only for noncommercial  
distribution and only if you received the program in object code or executable  
form with such an offer, in accord with Subsection b above.)  
The source code for a work means the preferred form of the work for making  
modifications to it. For an executable work, complete source code means  
all the source code for all modules it contains, plus any associated interface  
definition files, plus the scripts used to control compilation and installation of  
the executable. However, as a special exception, the source code distributed  
need not include anything that is normally distributed (in either source or  
binary form) with the major components (compiler, kernel, and so on) of the  
operating system on which the executable runs, unless that component itself  
RT-N1ꢀ B1  
Appendices  
48  
accompanies the executable.  
If distribution of executable or object code is made by offering access to copy  
from a designated place, then offering equivalent access to copy the source  
code from the same place counts as distribution of the source code, even  
though third parties are not compelled to copy the source along with the object  
code.  
4. You may not copy, modify, sublicense, or distribute the Program except as  
expressly provided under this License. Any attempt otherwise to copy, modify,  
sublicense or distribute the Program is void, and will automatically terminate  
your rights under this License. However, parties who have received copies, or  
rights, from you under this License will not have their licenses terminated so  
long as such parties remain in full compliance.  
ꢁ. You are not required to accept this License, since you have not signed it.  
However, nothing else grants you permission to modify or distribute the  
Program or its derivative works. These actions are prohibited by law if you do  
not accept this License. Therefore, by modifying or distributing the Program (or  
any work based on the Program), you indicate your acceptance of this License  
to do so, and all its terms and conditions for copying, distributing or modifying  
the Program or works based on it.  
6. Each time you redistribute the Program (or any work based on the Program),  
the recipient automatically receives a license from the original licensor to  
copy, distribute or modify the Program subject to these terms and conditions.  
You may not impose any further restrictions on the recipients’ exercise of the  
rights granted herein. You are not responsible for enforcing compliance by third  
parties to this License.  
7. If, as a consequence of a court judgment or allegation of patent infringement  
or for any other reason (not limited to patent issues), 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 distribute so as to satisfy simultaneously your obligations  
under this License and any other pertinent obligations, then as a consequence  
you may not distribute the Program at all. For example, if a patent license  
would not permit royalty-free redistribution of the Program by all those who  
receive copies directly or indirectly through you, then the only way you could  
satisfy both it and this License would be to refrain entirely from distribution of  
the Program.  
If any portion of this section is held invalid or unenforceable under any  
particular circumstance, the balance of the section is intended to apply and the  
section as a whole is intended to apply in other circumstances.  
It is not the purpose of this section to induce you to infringe any patents or  
other property right claims or to contest validity of any such claims; this section  
has the sole purpose of protecting the integrity of the free software distribution  
system, which is implemented by public license practices. Many people have  
Appendices  
RT-N1ꢀ B1  
49  
made generous contributions to the wide range of software distributed through  
that system in reliance on consistent application of that system; it is up to the  
author/donor to decide if he or she is willing to distribute software through any  
other system and a licensee cannot impose that choice.  
This section is intended to make thoroughly clear what is believed to be a  
consequence of the rest of this License.  
8. If the distribution and/or use of the Program is restricted in certain countries  
either by patents or by copyrighted interfaces, the original copyright holder  
who places the Program under this License may add an explicit geographical  
distribution limitation excluding those countries, so that distribution is permitted  
only in or among countries not thus excluded. In such case, this License  
incorporates the limitation as if written in the body of this License.  
9. The Free Software Foundation may publish revised and/or new versions of the  
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  
a version number of this License which applies to it and “any later version”, you  
have the option of following the terms and conditions either of that version or  
of any later version published by the Free Software Foundation. If the Program  
does not specify a version number of this License, you may choose any version  
ever published by the Free Software Foundation.  
10. If you wish to incorporate parts of the Program into other free programs whose  
distribution conditions are different, write to the author to ask for permission.  
For software which is copyrighted by the Free Software Foundation, write to  
the Free Software Foundation; we sometimes make exceptions for this. Our  
decision will be guided by the two goals of preserving the free status of all  
derivatives of our free software and of promoting the sharing and reuse of  
software generally.  
NO WARRANTY  
11 BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, 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.  
RT-N1ꢀ B1  
Appendices  
ꢁ0  
1ꢀ IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED  
TO IN WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER  
PARTY WHO MAY MODIFY AND/OR REDISTRIBUTE 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.
