Troubleshooting
Trobleshooting 4-1
This chapter gives tips on how to configure the communication
software. This chapter provides solutions to problems usually
encountered during the installation and operation of the Wireless
Network Access Point. Read the description below to solve your
problems.
4.1 Frequently Asked Questions
Can I run an application from a remote computer over the wireless
network？
This will depend on whether or not the application is designed to be
used over a network. Consult the application’s user guide to determine
if it supports operation over a network.
Can, I play computer games with other members of the cordless
network？
Yes, as long as the game supports multiple plays over a LAN (local
area network).Refer to the game’s user guide for more information.
What is the IEEE 802.11b standard？
The IEEE 802.11b Wireless LAN standards subcommittee, which is
formulating a standard for the industry. The objective is to enable
wireless LAN hardware from different manufactures to communicate.
What IEEE 802.11 feature are supported？
4-2 User Manual
The product supports the following IEEE 802.11 functions:
• CSMA/CA plus Acknowledge protocol
• Multi-Channel Roaming
• Automatic Rate Selection
• RTS/CTS feature
• Fragmentation
• Power Management
•
What is Ad-hoc？
An Ad-hoc integrated wireless LAN is a group of computers, each with
a WLAN adapter, Connected as an independent wireless LAN. Ad hoc
wireless LAN is applicable at a departmental scale for a branch or
SOHO operation.
What is Infrastructure？
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.
What is Roaming？
Roaming is the ability of a portable computer user to communicate
continuously while moving freely throughout an area greater than that
covered by a single Wireless Network Access Point. Before using the
roaming function, the workstation must make sure that it is the same
channel number with the Wireless Network Access Point of dedicated
coverage area.
Troubleshooting 4-3
To achieve true seamless connectivity, the wireless LAN must
incorporate a number of different functions. Each node and Wireless
Network Access Point, for example, must always acknowledge receipt
of each message. Each node must maintain contact with the wireless
network even when not actually transmitting data. Achieving these
functions simultaneously requires a dynamic RF networking technology
that links Wireless Network Access Points and nodes. In such a
system, the user’s end node undertakes a search for the best possible
access to the system. First, it evaluates such factors as signal strength
and quality, as well as the message load currently being carried by
each Wireless Network Access Point and the distance of each Wireless
Network Access Point to the wired backbone. Based on that
information, the node next selects the right Wireless Network Access
Points and registers its address. Communications between end node
and host computer can then transmitted up and down the backbone.
As the user moves on, the end nodes RF transmitter regularly checks
the system to determine whether it is in touch with the original or
Wireless Network Access Point whether it should seek a new one.
When a node no longer receives acknowledgment from its original
Wireless Network Access Point, it undertakes a new search. Upon
finding a new Wireless Network Access Point, it then re-registers, and
the communication process continues.
What is BSS ID？
A specific Ad hoc LAN is called a Basic Service Set (BSS). Computers
in a BSS must be configured with the same BSS ID.
What is ESS ID？
An Infrastructure configuration could also support roaming capability
for mobile workers. More than one BSS can be configured as an
Extended Service Set (ESS).Users within an ESS could Roam freely
between BSSs while served as a continuous connection to the network
wireless stations and Wireless Network Access Points within an ESS
must be configured with the same ESS ID and the same radio channel.
What is ISM band？
4-4 User Manual
The FCC and their counterpart 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.
What is 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).
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, 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.
Would the information be intercepted while transmitting on air？
Troubleshooting 4-5
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.
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.
What is WEP？
WEP is Wired Equivalent Privacy, a data privacy mechanism based on
a 40 bit shared key algorithm, as described in the IEEE 802 .11
standard.

encryption identified by the Access Point are allowed to associate with
it.
Both- With this setting stations communicate with or without data
encryption.
Operational Rate Set
By default the unit adaptively selects the highest possible ate for
transmission. In case of obstacles or interference, the system will step
down. Select the basic rates to be used among the following options 1 -
2 (Mpbs), 1 - 2 - 5.5 - 11 (Mbps). Select the Operational Rate set
among the following options, 82 84 8B 96 (1 – 2 - 5.5 - 11 Mbps) or 82
84 0B 16 (1 - 2 Mbps).
Beacon Period
Set the Beacon Period parameter, which specifies the duration
between the range 20-1000 with a typical value of 100.
DTIM
Set the DTIM period. Determines at which interval the AP will send its
broadcast traffic. Default value is 4 beacons.

WEP 128 keys #1-#4
The default key that will be used. May be edited if WEP type is 128 bits.
ESSID: It is an ASCII string up to 21 characters used to identify a
WLAN that prevents the unintentional merging of two co-located
WLANs. The ESSID value must be the same in all stations and Access
point in the extended WLAN. Select the ESSID to be used.
Channel: There are 14 channels available. The channels differ from
country to country. Select the channel to be used.
Fragmentation threshold: The size at which packets will be
fragmented. Choose a setting within a range of 256 to 2346 bytes.
RTS Threshold: Minimum packet size to require an RTS (Request To
Send). For packets smaller than this threshold, an RTS is not sent and
the packet is transmitted directly to the WLAN. This is the option for the
RTS Threshold activation.
Authentication Type: Select Open System, Shared Key, or Both
Open System: With this setting any station in the WLAN can
associate with an Access Point and receive and transmitted data
(null authentication).
Shared Key: With this setting only stations using a shared key
encryption identified by the Access Point are allowed to associate
with it.
Both: with this setting stations communicate with the Access
Point either with or without data encryption.
Appendix 5-7
Preamble Type (Short/Long): Preamble is the first sub field of PPDU,
which is the appropriate frame format for transmission to PHY (Physical
layer). There are two options, Short Preamble and Long Preamble. The
Short Preamble option improves throughput performance
Rate: By default the unit adoptively selects the highest possible rate for
transmission. Select the basic rates to be used among the following
options 1-2-5.5-11 (Mbps).
Auto Rate Fall Back: When this is enabled the transmission rate is the
optimum rate. In case of obstacles or interference, the system will
automatically fall back.
Regulatory Domain: The value of this field is already set and cannot
be modified.
