1. Introduction

ASUS 802.11g Access Point 9

Chapter 1 - Introduction

1. Introduction

1.4 Wireless Performance

This section provides the user with ideas for how to improve the performance
of an ASUS WLAN network.

1.4.1 Site Topography

For optimal performance, place wireless mobile clients and the ASUS AP s

away from transformers, heavy-duty motors, uorescent lights, microwave

ovens, refrigerators, and other industrial equipment. Signal loss can occur

when metal, concrete, walls or oors block transmission. Place the ASUS

APs in open areas or add the ASUS APs as needed to improve coverage.

Microwave ovens operate in the same frequency band as the ASUS AP. If
you use a microwave within range of the ASUS AP you may notice network
performance degradation. But, both your microwave and your the ASUS AP
will continue to function.

1.4.2 Range

Every environment is unique with different obstacles, barriers, materials, etc.

and, therefore, it is difcult to determine the exact range that will be achieved

without testing. However, has developed some guidelines to estimate the
range that users will see when the product is installed in their facility, but

there are no hard and fast specications.

Radio signals may reect off of some obstacles or be absorbed by others

depending on their construction. For example, with two 802.11b radios, you
may achieve up to 1000 in open space outdoors where two devices have a
line of sight, meaning they see each other with no obstacles. However, the
same two units may only achieve up to 300 of range when used indoors.

By default, the ASUS AP will automatically adjust the data rate to maintain
a usable radio connection. A client that is close to the ASUS AP may operate
at higher speeds while a client that is on the fringe of coverage may operate

at lower speeds. You can congure the data rates that the ASUS AP will

use. If you limit the range of data rates available to the ASUS AP, you may
reduce the effective wireless range of the WLAN coverage.

10 ASUS 802.11g Access Point

Chapter 1 - Introduction

1.4.3 Roaming Between ASUS APs

If there are multiple ASUS APs on the network, then a wireless mobile client
may seamlessly roam from one ASUS AP to another.

Each ASUS AP creates its own wireless cell or coverage area. This is
also known as a Basic Service Set (BSS). Any wireless mobile client can

communicate with a particular ASUS AP if it is within the ASUS AP’s

coverage area.

If the cells of multiple ASUS APs overlap, then the wireless mobile client
may switch from one ASUS AP to another as it travels throughout the
facility. During the hand-off from one ASUS AP to another, the wireless
mobile client maintains an uninterrupted connection to the network. This
is known as “roaming.”

Multiple ASUS APs connected to a common Ethernet network form an
Extended Service Set (ESS). All members of an Extended Service Set are

congured with an ID, known as the SSID or ESSID. Wireless mobile clients
must be congured with the same SSID as the ASUS APs on the network. A

client can only roam between ASUS APs that share the same SSID.

1.4.4 Roaming Guidelines

• An ASUS WLAN Card can only roam between APs of the same type.

• All ASUS APs must have the same SSID.

• All computers with ASUS WLAN Cards must have the same SSID as
the Access Points that they will roam.

• If WEP encryption is enabled, then all ASUS APs and client adapters
must use the same encryption level and WEP Key(s) to communicate.

• The ASUS APs’ cells must overlap to ensure that there are no gaps

in coverage and to ensure that the roaming client will always have a
connection available.

• ASUS APs that use the same Channel should be installed as far away
from each other as possible to reduce potential interference.

• It is strongly recommended that you perform a site survey using the utility
provided with the ASUS WLAN Card to determine the best location for
each ASUS AP in the facility.

3. Software
Access Point

Home Gateway

In this mode, use the Ethernet port to connect to the Internet through ADSL or
Cable Modem. In your environment, many users share the same IP to ISP.

In Home Gateway mode, Network Address Translation (NAT) is enabled,
which ensures network security. Each incoming or outgoing request goes
through a translation and authentication process. You can use PPPoE, DHCP
client, or static IP to make a WAN connection. In this mode, UPnP and DDNS
are also supported. These features are useful for home users.

Access Point

In Access Point mode, Ethernet port and wireless devices are set to locate in the
same local area network. Those WAN related functions are not supported here.

In Access Point mode, Network Address Translation (NAT) is disabled, one

64/128-bit versus 40/104-bit

The following section explains low-level (64-bit) and high-level (128-bit)
WEP Encryption schemes:

64-bit WEP Encryption

64-bit WEP and 40-bit WEP are the same encryption methods and can
interoperate in a wireless network. This level of WEP encryption uses a
40-bit (10 Hex character) encryption scheme as a secret key, which is set
by the user, and a 24-bit “Initialization Vector” scheme, which is not under
user control.

Chapter 3 - Software Conguration

Together these two schemes make a 64-bit (40 + 24) encryption scheme.
Some vendors refer to this level of WEP as 40-bit and others refer to this
as 64-bit. ASUS WLAN products use the term 64-bit when referring to this
lower level of encryption.

128-bit WEP Encryption

104-bit WEP and 128-bit WEP are the same encryption methods and can
interoperate on a wireless network. This level of WEP encryption uses a 104­bit (26 Hex character) encryption scheme as a secret key which is set by the
user, and a 24-bit “Initialization Vector”, which is not under user control.

32 ASUS 802.11g Access Point

Chapter 3 - Software Conguration

Together these two schemes make a 128-bit (104 + 24) encryption scheme.
Some vendors refer to this level of WEP as 104-bit and others refer to this
as 128-bit. ASUS WLAN products use the term 128-bit when referring to
this higher level of encryption.

Passphrase

Select “WEP-64bits” or “WEP-128bits” in the Encryption eld, and the

Access Point generates four WEP keys automatically. A combination of up

to 64 letters, numbers, or symbols is required. Alternatively, leave this eld

blank and type in four WEP keys manually.

WEP-64bit key: 10 hexadecimal digits (0~9, a~f, and A~F)
WEP-128bit key: 26 hexadecimal digits (0~9, a~f, and A~F)

Note: The ASUS WLAN family of products uses the same algorithm
to generate WEP keys. It eliminates the need for users to remember
passwords and maintains compatibility between products. But, this
method to generate WEP keys is not as secure as manual assign­ment.

WEP Key

You can set a maximum of four WEP keys. A WEP key is either 10 or 26
hexadecimal digits (0~9, a~f, and A~F) based on whether you select 64-bits
or 128-bits in the WEP pull-down menu. The ASUS 802.11g AP and ALL
of its wireless clients MUST have at least the same default key.

Key Index

The Default Key eld lets you specify which of the four encryption keys to

use to transmit data on your wireless LAN. As long as the ASUS 802.11g AP
or wireless mobile client with which you are communicating has the same
key in the same position, you can use any of the keys as the default key.
If the ASUS 802.11g AP and ALL of its wireless clients use the same four
WEP keys, select “key rotation” to maximize security. Otherwise, choose
one key in common as the default key.

Network Rotation Key Interval

This eld species the time interval (in seconds) after which a WPA group
key is changed. Enter ‘0’ (zero) to indicate that a periodic key-change is

not required.

Problem

My ASUS WLAN Card will not associate with the ASUS AP.

Solution

Follow these steps:

1. Make sure that your WLAN Card and your WLAN Access Point have

the same specications.

2. Try to bring the devices closer together; the ASUS WLAN Card may be
out of range of the ASUS AP.

3. Conrm that the ASUS AP and ASUS WLAN Card have the same

SSID.

4. Conrm that the ASUS AP and ASUS WLAN Card have the same

Encryption settings, if enabled.

5. Conrm that the ASUS AP’s Air and Link LEDs are solid green.

6. Conrm that the authorization table includes the MAC address of the

ASUS WLAN Card if “Authorization Table” is enabled.

7. Conrm that the operational mode is “Access Point” mode.

8. Conrm that the ASUS AP and ASUS WLAN Card have the same

preamble mode.

Problem

The throughput seems slow.

Solution

To achieve maximum throughput, verify that your antennas are well-placed,
not behind metal, and do not have too many obstacles between them. If you
move the client closer to the ASUS AP and throughput increases, you may
want to consider adding a second ASUS AP and implementing roaming.

• Check antenna, connectors and cabling.

• Verify network trafc does not exceed 37% of bandwidth.

• Check to see that the wired network does not exceed ten broadcast
messages per second.

• Verify wired network topology and conguration.

Glossary

Access Point (AP)

A networking device that seamlessly connects wired and wireless networks.
Access Points combined with a distributed system support the creation of
multiple radio cells that enable roaming throughout a facility.

Ad Hoc

A wireless network composed solely of stations within mutual communication
range of each other (no Access Point).

AES(Advance Encryption Standard)

AES is the U.S. government’s next-generation cryptography algorithm,

which will replace DES and 3DES. This encryption key protocol is applied in

802.1i standard to improve WLAN security. AES will require new hardware,

in contrast with TKIP that can be used on existing wireless devices.

Basic Service Area (BSS)

A set of stations controlled by a single coordination function.

Broadband

A type of data transmission in which a single medium (such as cable) carries
several channels of data at once.

Channel

An instance of medium use for the purpose of passing protocol data units
that may be used simultaneously, in the same volume of space, with other
instances of medium use (on other channels) by other instances of the same

5. Appendix

physical layer, with an acceptably low frame error ratio due to mutual
interference.

Client

A client is the desktop or mobile PC that is connected to your network.

COFDM (for 802.11a or 802.11g)

Signal power alone is not enough to maintain 802.11b-like distances in an

802.11a/g environment. To compensate, a new physical-layer encoding

technology was designed that departs from the traditional direct-sequence
technology being deployed today. This technology is called COFDM (coded

OFDM). COFDM was developed specically for indoor wireless use and

offers performance much superior to that of spread-spectrum solutions.
COFDM works by breaking one high-speed data carrier into several

52 ASUS 802.11g Access Point

Chapter 5 - Appendix

lower-speed subcarriers, which are then transmitted in parallel. Each high­speed carrier is 20 MHz wide and is broken up into 52 subchannels, each
approximately 300 KHz wide. COFDM uses 48 of these subchannels for
data, while the remaining four are used for error correction. COFDM delivers

higher data rates and a high degree of multipath reection recovery, thanks

to its encoding scheme and error correction.

Each subchannel in the COFDM implementation is about 300 KHz wide.
At the low end of the speed gradient, BPSK (binary phase shift keying) is
used to encode 125 Kbps of data per channel, resulting in a 6,000-Kbps, or
6 Mbps, data rate. Using quadrature phase shift keying, you can double the
amount of data encoded to 250 Kbps per channel, yielding a 12-Mbps data
rate. And by using 16-level quadrature amplitude modulation encoding 4 bits
per hertz, you can achieve a data rate of 24 Mbps. The 802.11a/g standard

species that all 802.11a/g-compliant products must support these basic data

rates. The standard also lets the vendor extend the modulation scheme beyond
24 Mbps. Remember, the more bits per cycle (hertz) that are encoded, the
more susceptible the signal will be to interference and fading, and ultimately,
the shorter the range, unless power output is increased.

Device Name

Also known as DHCP client ID or network name. Sometimes provided by
an ISP when using DHCP to assign addresses.

DHCP (Dynamic Host Conguration Protocol)

This protocol allows a computer (or many computers on your network) to
be automatically assigned a single IP address from a DHCP server.

DNS Server Address (Domain Name System)

DNS allows Internet host computers to have a domain name and one or
more IP addresses. A DNS server keeps a database of host computers and
their respective domain names and IP addresses, so that when a user enters
a domain name into the Internet browser, the user is sent to the proper IP
address. The DNS server address used by the computers on your home
network is the location of the DNS server your ISP has assigned.

DSL Modem (Digital Subscriber Line)

A DSL modem uses your existing phone lines to transmit data at high
speeds.

Direct-Sequence Spread Spectrum (for 802.11b)

Spread spectrum (broadband) uses a narrowband signal to spread the
transmission over a segment of the radio frequency band or spectrum.

ASUS 802.11g Access Point 53

5. Appendix

Chapter 5 - Appendix

Direct-sequence is a spread spectrum technique where the transmitted signal
is spread over a particular frequency range.

Direct-sequence systems communicate by continuously transmitting a
redundant pattern of bits called a chipping sequence. Each bit of transmitted
data is mapped into chips and rearranged into a pseudorandom spreading
code to form the chipping sequence. The chipping sequence is combined
with a transmitted data stream to produce the output signal.

Wireless mobile clients receiving a direct-sequence transmission use the
spreading code to map the chips within the chipping sequence back into bits
to recreate the original data transmitted by the wireless device. Intercepting

and decoding a direct-sequence transmission requires a predened algorithm

to associate the spreading code used by the transmitting wireless device to
the receiving wireless mobile client.

This algorithm is established by IEEE 802.11b specications. The bit

redundancy within the chipping sequence enables the receiving wireless
mobile client to recreate the original data pattern, even if bits in the chipping
sequence are corrupted by interference. The ratio of chips per bit is called the
spreading ratio. A high spreading ratio increases the resistance of the signal
to interference. A low spreading ratio increases the bandwidth available to
the user. The wireless device uses a constant chip rate of 11Mchips/s for all
data rates, but uses different modulation schemes to encode more bits per chip
at the higher data rates. The wireless device is capable of an 11 Mbps data
transmission rate, but the coverage area is less than a 1 or 2 Mbps wireless
device since coverage area decreases as bandwidth increases.

Encryption

This provides wireless data transmissions with a level of security.

Extended Service Set (ESS)

5. Appendix

A set of one or more interconnected basic service set (BSSs) and integrated

local area networks (LANs) can be congured as an Extended Service

Set.

ESSID (Extended Service Set Identier)

You must have the same ESSID entered into the gateway and each of

its wireless clients. The ESSID is a unique identier for your wireless

network.

Ethernet

The most widely used LAN access method, which is dened by the IEEE

802.3 standard. Ethernet is normally a shared media LAN meaning all devices

54 ASUS 802.11g Access Point

Chapter 5 - Appendix

on the network segment share total bandwidth. Ethernet networks operate
at 10Mbps using CSMA/CD to run over 10-BaseT cables.

Firewall

A rewall determines which information passes in and out of a network.
NAT can create a natural rewall by hiding a local network’s IP addresses

from the Internet. A Firewall prevents anyone outside of your network from

accessing your computer and possibly damaging or viewing your les.

Gateway

A network point that manages all the data trafc of your network, as well

as to the Internet and connects one network to another.

IEEE

The Institute of Electrical and Electronics Engineers. The IEEE sets
standards for networking, including Ethernet LANs. IEEE standards ensure
interoperability between systems of the same type.

IEEE 802.11

IEEE 802.xx is a set of specications for LANs from the Institute of Electrical

and Electronic Engineers (IEEE). Most wired networks conform to 802.3,

the specication for CSMA/CD based Ethernet networks or 802.5, the
specication for token ring networks. 802.11 denes the standard for wireless

LANs encompassing three incompatible (non-interoperable) technologies:
Frequency Hopping Spread Spectrum (FHSS), Direct Sequence Spread

Spectrum (DSSS), and Infrared. 802.11 species a carrier sense media access
control and physical layer specications for 1 and 2 Mbps wireless LANs.

IEEE 802.11a (54Mbits/sec)

Compared with 802.11b: The 802.11b standard was designed to operate

in the 2.4-GHz ISM (Industrial, Scientic and Medical) band using direct-

sequence spread-spectrum technology. The 802.11a standard, on the other
hand, was designed to operate in the more recently allocated 5-GHz UNII
(Unlicensed National Information Infrastructure) band. And unlike 802.11b,
the 802.11a standard departs from the traditional spread-spectrum technology,

instead using a frequency division multiplexing scheme that’s intended to
be friendlier to ofce environments.

The 802.11a standard, which supports data rates of up to 54 Mbps, is the
Fast Ethernet analog to 802.11b, which supports data rates of up to 11 Mbps.
Like Ethernet and Fast Ethernet, 802.11b and 802.11a use an identical
MAC (Media Access Control). However, while Fast Ethernet uses the same

ASUS 802.11g Access Point 55

5. Appendix

physical-layer encoding scheme as Ethernet (only faster), 802.11a uses an
entirely different encoding scheme, called OFDM (orthogonal frequency
division multiplexing).

The 802.11b spectrum is plagued by saturation from wireless phones,
microwave ovens and other emerging wireless technologies, such as
Bluetooth. In contrast, 802.11a spectrum is relatively free of interference.

The 802.11a standard gains some of its performance from the higher
frequencies at which it operates. The laws of information theory tie frequency,
radiated power and distance together in an inverse relationship. Thus, moving
up to the 5-GHz spectrum from 2.4 GHz will lead to shorter distances, given
the same radiated power and encoding scheme.

Compared with 802.11g: 802.11a is a standard for access points and radio
NICs that is ahead of 802.11g in the market by about six months. 802.11a
operates in the 5GHz frequency band with twelve separate non-overlapping
channels. As a result, you can have up to twelve access points set to different
channels in the same area without them interfering with each other. This

makes access point channel assignment much easier and signicantly

increases the throughput the wireless LAN can deliver within a given area.
In addition, RF interference is much less likely because of the less-crowded
5 GHz band.

IEEE 802.11b (11Mbits/sec)

In 1997, the Institute of Electrical and Electronics Engineers (IEEE) adopted
the 802.11 standard for wireless devices operating in the 2.4 GHz frequency
band. This standard includes provisions for three radio technologies: direct
sequence spread spectrum, frequency hopping spread spectrum, and infrared.
Devices that comply with the 802.11 standard operate at a data rate of either
1 or 2 Mbps.

In 1999, the IEEE created the 802.11b standard. 802.11b is essentially

5. Appendix

identical to the 802.11 standard except 802.11b provides for data rates of
up to 11 Mbps for direct sequence spread spectrum devices. Under 802.11b,
direct sequence devices can operate at 11 Mbps, 5.5 Mbps, 2 Mbps, or 1
Mbps. This provides interoperability with existing 802.11 direct sequence
devices that operate only at 2 Mbps.

Direct sequence spread spectrum devices spread a radio signal over a range of

frequencies. The IEEE 802.11b specication allocates the 2.4 GHz frequency

band into 14 overlapping operating Channels. Each Channel corresponds to
a different set of frequencies.

Chapter 5 - Appendix

IEEE 802.11g

802.11g is a proposed (to be nalized) new extension to 802.11b (used in

Chapter 5 - Appendix

majority of wireless LANs today) that broadens 802.11b’s data rates to 54

Mbps within the 2.4 GHz band using OFDM (orthogonal frequency division
multiplexing) technology. 802.11g allows backward compatibility with

802.11b devices but only at 11 Mbps or lower, depending on the range and
presence of obstructions.

• 10mW for the entire 2.4 GHz band (2400 MHz–2483.5 MHz)

• 100mW for frequencies between 2446.5 MHz and 2483.5 MHz

NOTE: Channels 10 through 13 inclusive operate in the band 2446.6
MHz to 2483.5 MHz.

There are few possibilities for outdoor use: On private property or on the
private property of public persons, use is subject to a preliminary authorization
procedure by the Ministry of Defense, with maximum authorized power of
100mW in the 2446.5–2483.5 MHz band. Use outdoors on public property
is not permitted.

In the departments listed below, for the entire 2.4 GHz band:

• Maximum authorized power indoors is 100mW

• Maximum authorized power outdoors is 10mW

Departments in which the use of the 2400–2483.5 MHz band is permitted
with an EIRP of less than 100mW indoors and less than 10mW outdoors:

01 Ain Orientales 36 Indre 66 Pyrénées
02 Aisne 37 Indre et Loire 67 Bas Rhin
03 Allier 41 Loir et Cher 68 Haut Rhin
05 Hautes Alpes 42 Loire 70 Haute Saône
08 Ardennes 45 Loiret 71 Saône et Loire
09 Ariège 50 Manche 75 Paris
11 Aude 55 Meuse 82 Tarn et Garonne
12 Aveyron 58 Nièvre 84 Vaucluse
16 Charente 59 Nord 88 Vosges

25 Doubs 61 Orne 90 Territoire de Belfort
26 Drôme 63 Puy du Dôme 94 Val de Marne
32 Gers 64 Pyrénées Atlantique

This requirement is likely to change over time, allowing you to use your
wireless LAN card in more areas within France. Please check with ART for

Appendix - GNU General Public License

Preamble

The licenses for most software are designed to take away your freedom to
share and change it. By contrast, he 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 ther 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 reedom, 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 chnge 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 restritions
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 ou 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 (2)
offer you this license which gies you legal permission to copy, distribute
and/or modify the software.

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 modied by soeone 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 reect on the original authors’ reputations.

Finally, any free program is threatened constantly by sftware 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

ree use or not licensed at all.

The precise terms and conditions for copying, distribution and modication

follow.

Appendix - GNU General Public License

Term s & con d it io ns for copy in g, dist ri bu ti on , &

modication

0. This License applies to any proram 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
eitherthe 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 modications and/or translated into another language. (Hereinafter,
translation is included without limitaton in the term “modication”.)

Each licensee is addressed as “you”.

Activities other than copying, distribution and modication are not

covered by this License; they are outside its scope. The act of running
the Program is not restricted, and the otput 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 copis 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 o 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 exchang for a fee.

2. 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 modications or work under the terms of Section 1 above, provided

that you also meet all ofthese conditions:

a) You must cause the modied les to carry prominent notices stating

that you changed the les 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 s 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.

68 ASUS 802.11g Access Point

Appendix - GNU General Public License

c) If the modied program normally reads commands interactively

when run, you must cause it, when started unning 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 th 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
announement.)

These requirements apply to the modied work as a whole. If identiable

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, d 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
permissons 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 xercise 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 storageor 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 2) in object code or executable form under the terms of Sections
1 and 2 above provded 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 2 above on a medium customarily used for software interchange;
or,

ASUS 802.11g Access Point 69

Appendix - GNU General Public License

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 bedistributed under the terms of
Sections 1 and 2 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 allowe 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 modicationsto it. For an executable work, complete source code

means all the source code for all modules it contains, plus any associated

interface denition les, plus the scripts used to control compilation and

installation of the executable. However, as a spcial 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 omponent itself 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 te 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
cop, 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 sch parties remain in full
compliance.

70 ASUS 802.11g Access Point

Appendix - GNU General Public License

5. 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 prohibite 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 moding 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 trms
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 judgmentor 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 coditions 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 ould
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.

I 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 sectin 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 licens
practices. Many people have 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 softare through any other system and a licensee
cannot impose that choice.

ASUS 802.11g Access Point 71

Appendix - GNU General Public License

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 restrictd 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 permtted 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 Licens 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

species a version number of his 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
f 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 permision. 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 fre 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 STATEDIN 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. TH 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.

12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR
AGREED TO IN WRTING WILL ANY COPYRIGHT HOLDER, OR
ANY OTHER PARTY WHO MAY MODIFY AND/OR REDISTRIBUTE
THE PROGRA M 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 SE 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 OFTHE POSSIBILITY OF SUCH
DAMAGES.
