Soft AP mode allows you to configure Access Control settings.
Access Control
The AP provides facilities to limit the wireless clients that associate with it and
the data packets that can forward through it. Filters provide network security or
improve performance by eliminating broadcast/multicast packets from the radio
network.
The Access Control List (ACL) contains MAC addresses for wireless
clients allowed to associate with the AP. This provides security by
preventing unauthorized access. The AP also uses a disallowed address
list of destinations. This feature prevents the AP from communicating with
specified destinations. This can include network devices that do not require
communication with the AP or its wireless clients.

5. Troubleshooting
The following troubleshooting guides provide answers to some of the more
common problems, which you may encounter while installing or using WLAN
Adapter products. If you encounter difficulties that are not mentioned in this
section, please contact the Wireless LAN Technical Support.
Verify if the WLAN Adapter is installed correctly.
When the WLAN Adapter setup is complete, you can verify if the driver has
been setup properly. Right click My Computer, select Properties, and click
the Device Manager tab. Then double-click the Network adapters icon; you
should see “802.11g Network Adapter” with an icon of an expansion adapter.
There should not be a “!” or “?” (problem) or “x” (disabled) symbol over this
icon.
There is a yellow exclamation mark or a yellow question mark in
Device Manager in front of my WLAN Adapter.
To resolve the problem, you should update/reinstall the WLAN Adapter driver.
In “Device Manager”, right click 802.11g Network Adapter, select Properties,
and select Driver tab. Click on Update Driver button, then follow the “Update
Device Driver Wizard” to complete the driver installation.

Cannot connect to a Station (WLAN Adapter)
Follow the procedure below to configure your WLAN Adapter.
a. Verify that the “Network Type” is in “Ad Hoc” mode.
b. Verify that the “SSID” of your WLAN Adapter is set to the same “SSID” of
the other station (or another WLAN Adapter).
c. Verify that the “channel” of the WLAN Adapter is “Auto” or set to the
same “channel” of the other station (or another WLAN Adapter).
d. Verify that the “Encryption” type is the same as the other station (or another
WLAN Adapter). If “WEP” encryption is enabled, you must set the same
“WEP” Keys on both stations.
Bad link quality or bad signal strength
There are two possible reasons. First is radio interference, keep the
environment around the WLAN Adapter away from microwave ovens and large
metal objects. Then try to reorient the WLAN Adapter antenna. Second is the
distance, decrease the distance between your WLAN Adapter and the access
point or station (or another WLAN Adapter).
Chapter 4
Troubleshooting
The TCP/IP protocol did not bind to the WLAN PC Adapter.
This will occur when the computer already has six TCP/IP bindings in Windows
98 or ten bindings in Windows Me. These limits are imposed by the Microsoft
operating system.
Solution: If your computer already has the maximum number of TCP/IP
bindings, remove one of the network adapters from the Network configuration
before installing the WLAN Adapter driver.

Glossary
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 specifically 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 lower-speed subcarriers, which are then
transmitted in parallel. Each high-speed 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 reflection
recovery, thanks to its encoding scheme and error correction.
46
ASUS WLAN Adapter
Chapter 6 - Glossary
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 specifies 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.
Default Key
This option allows you to select the default WEP key. This option allows you to
use WEP keys without having to remember or write them down. The WEP keys
generated using the Passphrase is compatible with other WLAN products. The
Passphrase option is not as secure as manual assignment.
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 Configuration 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.

Glossary
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. Direct-sequence is a
spread spectrum technique where the transmitted signal is spread over a particular
frequency range.
ASUS WLAN Adapter
47
Chapter 6 - Glossary
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 directsequence transmission requires a predefined 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 specifications. 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. This option
allows you to specify a 64-bit or a 128-bit WEP key. A 64-bit encryption contains
10 hexadecimal digits or 5 ASCII characters. A 128-bit encryption contains 26
hexadecimal digits or 13 ASCII characters.
64-bit and 40-bit WEP keys use the same encryption method and can interoperate
on wireless networks. This lower level of WEP encryption uses a 40-bit (10
hexadecimal digits assigned by the user) secret key and a 24-bit Initialization
Vector assigned by the device. 104-bit and 128-bit WEP keys use the same
encryption method.
All wireless clients in a network must have identical WEP keys with the access
point to establish connection. Keep a record of the WEP encryption keys.
Chapter 5
Glossary
Extended Service Set (ESS)
A set of one or more interconnected basic service set (BSS) and integrated
local area networks (LANs) can be configured as an Extended Service Set.
ESSID (Extended Service Set Identifier)
You must have the same ESSID entered into the gateway and each of its wireless
clients. The ESSID is a unique identifier for your wireless network.

Ethernet
The most widely used LAN access method, which is defined by the IEEE 802.3
standard. Ethernet is normally a shared media LAN meaning all devices on the
network segment share total bandwidth. Ethernet networks operate at 10Mbps
using CSMA/CD to run over 10-BaseT cables.
Firewall
A firewall determines which information passes in and out of a network. NAT can
create a natural firewall 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 files.
Gateway
A network point that manages all the data traffic 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 specifications for LANs from the Institute of Electrical
and Electronic Engineers (IEEE). Most wired networks conform to 802.3, the
specification for CSMA/CD based Ethernet networks or 802.5, the specification for
token ring networks. 802.11 defines 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 specifies a carrier sense media access control and physical layer
specifications for 1 and 2 Mbps wireless LANs.
IEEE 802.11a (54Mbits/sec)
Chapter 5
Glossary
Compared with 802.11b: The 802.11b standard was designed to operate in
the 2.4-GHz ISM (Industrial, Scientific 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 office 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 physical-layer
encoding scheme as Ethernet (only faster), 802.11a uses an entirely different
encoding scheme, called OFDM (orthogonal frequency division multiplexing).
ASUS WLAN Adapter
49
Chapter 6 - Glossary
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 significantly 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 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 specification allocates the 2.4 GHz frequency band
into 14 overlapping operating Channels. Each Channel corresponds to a different
set of frequencies.
IEEE 802.11g
Chapter 5
Glossary
802.11g is a new extension to 802.11b (used in 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.
Infrastructure
A wireless network centered about an access point. In this environment, the access
point not only provides communication with the wired network but also mediates
wireless network traffic in the immediate neighborhood.

MAC Address (Media Access Control)
A MAC address is the hardware address of a device connected to a network.
NAT (Network Address Translation)
Chapter 5
Glossary
NAT masks a local network’s group of IP addresses from the external network,
allowing a local network of computers to share a single ISP account. This process
allows all of the computers on your home network to use one IP address. This will
enable access to the Internet from any computer on your home network without
having to purchase more IP addresses from your ISP.
NIC (Network Interface Card)

Radio Frequency (RF) Terms: GHz, MHz, Hz
The international unit for measuring frequency is Hertz (Hz), equivalent to the
older unit of cycles per second. One megahertz (MHz) is one million Hertz. One
gigahertz (GHz) is one billion Hertz. The standard US electrical power frequency is
60 Hz, the AM broadcast radio frequency band is 0.55-1.6 MHz, the FM broadcast
radio frequency band is 88-108 MHz, and wireless 802.11 LANs operate at 2.4
GHz.
SSID (Service Set Identifier)
Chapter 5
Glossary
SSID is a group name shared by every member of a wireless network. Only client
PCs with the same SSID are allowed to establish a connection. Enabling the
Response to Broadcast SSID requests option allows the device to broadcast
its SSID in a wireless network. This allows other wireless devices to scan and
establish communication with the device. Unchecking this option hides the SSID to
prevent other wireless devices from recognizing and connecting to the device.
