Troubleshooting
This section provides solutions to problems usually encountered during the installation and
operation of this Wireless LAN USB Adapter. Read the description below to solve your
problems.
ü If you encounter difficulty using / installing the Wireless LAN USB Adapter, this
may be related to various causes:
lOut-of range situation, which prevents the card from establishing a wireless
connection with the network.
lConfiguration mismatch, which prevents the card from establishing a wireless
connection with the (correct) network.
lAbsence of, or conflict of the Wireless LAN USB Adapter driver.
lA problem or conflict with the connector, which prevents the Wireless LAN USB
Adapter from powering on.
lA conflict of the hardware with another device.
ü What does IEEE 802.11 feature support
？
lCSMA/CA plus Acknowledge Protocol
lMulti-Channel Roaming
lAutomatic Rate Selection
lRTS/CTS Feature
lFragmentation
lPower Management
ü Can Wireless products support printer sharing
？
Wireless products perform the same function as LAN products. Therefore, Wireless
products can work with Netware, Windows NT/2000, or other LAN operating systems to
support printer or file sharing.
ü Would the information be intercepted while transmitting on air
？
WLAN features two-fold protection in security. On the hardware side, as with Direct
Sequence Spread Spectrum technology, it has the inherent security feature of
scrambling. On the software side, WLAN series offer the encryption function (WEP) to
enhance security and Access Control. Users can set it up depending upon their needs.
ü What is DSSS
？
What is FHSS
？
And what are their differences
？
Frequency-hopping spread-spectrum (FHSS) uses a narrowband carrier that changes
frequency in a pattern that is known to both transmitter and receiver. Properly
synchronized, the net effect is to maintain a single logical channel. To an unintended
receiver, FHSS appears to be short-duration impulse noise. Direct-sequence spread-
spectrum (DSSS) generates a redundant bit pattern for each bit to be transmitted. This
bit pattern is called a chip (or chipping code). The longer the chip is, the greater the
probability that the original data can be recovered. Even if one or more bits in the chip
are damaged during transmission, statistical techniques embedded in the radio can
recover the original data without-the need for retransmission. To an unintended
receiver, DSSS appears as low power wideband noise and is rejected (ignored) by
most narrowband receivers.

Glossary
A
Ad-Hoc Mode - A client setting that provides independent peer-to-peer connectivity in a
wireless LAN. An alterative setup is where PCs communicate with each other through an
access point. An Ad-hoc integrated wireless LAN is a group of computers, each has a
Wireless LAN adapter, Connected as an independent wireless LAN. Ad hoc wireless LAN is
applicable at a departmental scale for a branch or SOHO operation.
B
Bandwidth - The transmission capacity of a given facility, in terms of how much data the
facility can transmit in a fixed amount of time; expressed in bits per second (bps).
Bit - A binary digit. The value (0 or 1) used in the binary numbering system. Also, the
smallest form of data.
BSSID - A specific Ad hoc LAN is called a Basic Service Set (BSS). Computers in a BSS
must be configured with the same BSS ID.
D
Default Gateway - The routing device used to forward all traffic that is not addressed to a
station within the local subnet.
DHCP server and client - DHCP stands for Dynamic Host Configuration Protocol. This
protocol is designed to automatically load parameters for the TCP/IP network, including the
IP address, host name, domain name, net-mask, default gateway, and name server address.
The machine that provides this service is called the DHCP server, and its client computers
are called DHCP clients. If client computers support DHCP, a TCP/IP configuration is not
needed on each client computer.
Domain - A sub-network comprised of a group of clients and servers under the control of
one security database. Dividing LANs into domains improves performance and security.
Driver - A workstation or server software module that provides an interface between a
network interface card and the upper-layer protocol software running in the computer; it is
designed for a specific NIC, and is installed during the initial installation of a network-
compatible client or server operating system.
DSSS (Direct-Sequencing Spread-Spectrum) - DSSS operate over the radio airwaves in
the unlicensed ISM band (industrial, scientific, medical). DSSS uses a radio transmitter to
spread data packets over a fixed range of frequency band.
Wireless LAN USB Adapter
18
E
Encryption - A security method that applies a specific algorithm to data in order to alter the
data's appearance and prevent other devices from reading the information.
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 10Mbp using CSMA/CD to run
over 10Base T cables.
F
Firmware - Program that is inserted into programmable read-only memory (programmable
read-only memory), thus becoming a permanent part of a computing device.
Fragmentation Threshold Value - Indicates how much of the network resources is devoted
to recovering packet errors. The value should remain at its default setting of 2,432. If you
experience high packet error rates, you can decrease this value but it will likely decrease
overall network performance. Only minor modifications of this value are recommended.
Fragmentation - Breaking a packet into smaller units when transmitting over a network
medium that cannot support the original size of the packet.
I
IEEE - The Institute of Electrical and Electronics Engineers
IEEE 802.11b standard - The IEEE 802.11b Wireless LAN standards subcommittee
formulating standards for the industry. The objective is to enable wireless LAN hardware
from different manufacturers to communicate.
Infrastructure Mode - A client setting providing connectivity to an Access Point. As
compared to Ad-Hoc Mode where PCs communicate directly with each other clients set in
infrastructure Mode all pass data through a central Access Point. The Access Point not only
mediates Wireless network traffic in the immediate neighborhood but also pro-vides
communication with the wired network. An integrated wireless and wireless and wired LAN
is called an Infrastructure configuration. Infrastructure is applicable to enterprise scale for
wireless access to central database, or wireless application for mobile workers.
IP Address - An IP address is a 32-bit number that identifies each sender & receiver of
information that is sent across the Internet. An IP address has two parts: the identifier of a
particular network on the Internet and one identifier of a particular device (which can be a
server or a workstation within that network).
ISM band - The FCC and their counterparts outside of the U.S. have set aside bandwidth
for unlicensed use in the ISM (Industrial, Scientific and Medical) band. Spectrum in the
vicinity of 2.4 GHz, in particular, is being made available worldwide. This presents a truly
revolutionary opportunity to place convenient high-speed wireless capabilities in the hands
of users around the globe.
L
Wireless LAN USB Adapter
19
LAN - A local area network (LAN) is a group of computers and associated devices that
share a common communications line and typically share the resources of a single
processor or server within a small geographic area (for example, within an office building).
M
MAC Address - 12-digit hexadecimal number that identifies a networking product on the
network.
Mbps (Megabits per second) - One million bits per second; unit of measurement for data
transmission.
N
Network - A system that transmits any combination of voice, video and/or data between
users.
Node - A network junction or connection point, typically a computer or work station.
O
Open System - Is when the sender and the recipient do not share a secret key. Each party
generates its own key-pair and asks the receiver to accept the (usually randomly) generated
key. Once accepted, this key is used for a short time only; then a new key is generated and
agreed upon.
P
Packet - A unit of data routed between an origin and a destination in a network.
PCMCIA - Personal Computer Memory Card International Association
Plug and Play - The ability of a computer system to configure expansion boards and other
devices automatically without requiring the user to turn off the system during installation.
R
Roaming - The ability to use a wireless device and be able to move from one access point's
range to another without losing the connection.
RTS/CTS Threshold Value - Should remain at its default setting of 2,347. A preamble is a
signal used to synchronize the transmission timing between two or more systems. A series
of transmission pulses is sent before the data to indicate that “someone is about transmit
data.” This ensures that systems receiving the information correctly when the data
transmission starts.
S
Shared Key - Is when both the sender and recipient share a secret key. Both units use this
key for an extended length of time, sometimes indefinitely. Any eavesdropper that discovers
the key may decipher all packets until the key is changed.
Wireless LAN USB Adapter
20
Signal Strength - The signal level indicates the strength of the signal as received at the
wireless network interface.
SNMP (Simple Network Management Protocol) - A standard network protocol that can be
used to manage networks locally, or worldwide via the Internet.
Spread Spectrum - Spread Spectrum technology is a wideband radio frequency technique
developed by the military for use in reliable, secure, mission-critical communication systems.
It is designed to trade off bandwidth efficiency for reliability, integrity, and security. In other
words, more bandwidth is consumed than in the case of narrowband transmission, but the
trade off produces a signal that is, in effect, louder and thus easier to detect, provided that
the receiver knows the parameters of the spread-spectrum signal being broadcast. If a
receiver is not tuned to the right frequency, a spread –spectrum signal looks like
background noise. There are two main alternatives, Direct Sequence Spread Spectrum
(DSSS) and Frequency Hopping Spread Spectrum (FHSS).
SSID (Service Set Identifier) - Is the unique name shared among all points in a wireless
network. The SSID must be identical for all points in the network. It is case sensitive and
must not exceed 32 characters.
Static IP Address - A permanent IP address that is assigned to a node in an IP or a TCP/IP
network.
Subnet - A subnet is a logical sub-division of a Local Area Network that has been divided
by means of routers or gateways. A subnet may include multiple LAN segments. Each
subnet is identified by the Subnet Mask.
T
TCP/IP (Transmission Control Protocol/Internet Protocol) - The basic communication
language or protocol of the Internet. It can also be used as a communications protocol in a
private network (either an intranet or an extranet). When you are set up with direct access
to the Internet, your computer is provided with a copy of the TCP/IP program just as every
other computer that you may send messages to or get information from also has a copy of
TCP/IP.
W
WEP (Wired Equivalent Privacy) - A data privacy mechanism based on a 40 bit shared key
algorithm, as described in the IEEE 802 .11 standard. The optional cryptographic
confidentiality algorithm specified by IEEE 802.11 used to provide data confidentiality that is
subjectively equivalent to the confidentiality of a wired LAN medium that does not employ
cryptographic techniques to enhance privacy.
Windows workgroup - A Windows workgroup can consist of either wireless or wired
network connections or a combination of the two. Usually a Windows workgroup consists of
members who are related because of a shared function, e.g. members of the same
department. For a Windows workgroup it is not relevant where the workgroup participants
are located, since the members of a Windows workgroup are identified by their workgroup
name only.
