1-3 System Configurations
The 11Mbp Wireless Access Point can be configured in a variety of network system
configurations.
Wireless Infrastructure
In a wireless infrastructure, the 11Mbps Access Point acts as a bridge. The Access Point
connects the wireless clients together. The Access Point acts as a center point for all
wireless communications. This would increase efficiency of the communications since
the wireless adapters do not need to be within direct range of each other.
Wireless Infrastructure with Stations Attaching to a Wired
LAN
The 11Mbps Wireless LAN Access Point will provide access to your local LAN. An
integrated wireless and wired LAN is called an Infrastructure configuration. A group of
wireless LAN PC users and an Access Point construct a Basic Service Set (BSS). Each
wireless PC in this BSS can talk to any computer on your network via the Access Point.
Connecting the Wireless LAN Micro Access Point to your
network
Connecting with Cable/DSL mode, the 11Mbps Wireless LAN Access Point provides
you high-speed broadband-sharing gateway.
Point-to-Point/Point-to-Multipoint Connection
The 11Mbps Wireless Access Point provides ideal bridging solution for inter-building
LANs connection. In an inter-building application, the 11Mbps Access Point acts as a
repeater, thus expanding and connecting corporate LANs with reliable and high-speed
connection.

2-4 Hardware Installations
Take the following steps to set up your Access Point.
Site Selection: Before installation, determine the Access Point location. Proper
placement of the Access Point is critical to ensure optimum radio range and performance.
You may use the Site Survey and Access Points Browser utility (The utilities included
with the wireless PC Card) to choose a proper placement for your Access Point.
Typically, the best location to place your Access Point at your site is the center of your
wireless coverage area. Try to place your mobile stations within the line of sight.
Obstructions may impede performance of the Access Point.
Access Point Placement You can place the Access Point on a flat surface such as a table
or cabinet, or mount the unit on a vertical surface like a wall. The integrated antenna of
your Access Point performs best in an open environment with as few obstructions as
possible. In most situations placing the Access Point as pictured below will provide
satisfactory performance results.
Connect the Ethernet Cable The 11Mbps Wireless LAN Access Point supports
10/100M Ethernet connection. Attach your UTP Ethernet cable to the RJ-45 connector on
the Access Point. Then connect the other end of the RJ-45 cable to a hub or a station.
Please be aware that, use the MDI port to connect the Access Point to a hub. Otherwise,
please use the MDI-X port to connect the Access Point to a computer/station.
Connect the Power Cable Connect the power adapter to the power socket on the Access
Point, and plug the other end of the power into an electrical outlet. The Access Point will
be powered on and all five indicators on the top panel will flash in sequence to test the
functionality of the indicators.
NOTE: ONLY use the power adapter supplied with the Access Point. Otherwise, the
product may be damaged.
Chapter 3 Configuring the Access Point
The 11Mbps Wireless LAN Access Point is shipped with default parameters, which will
be suitable for the typical infrastructure wireless LAN. Just simply install the Access
Point, power it on, and it is now ready to work. Nevertheless, you can still adjust
configuration settings depending on how you would like to manage your wireless
network. The 11Mbps Wireless Access Point allows for configuration either via the
configuration utility, known as Access Point Manager, console port connection, or
anywhere through a TCP/IP (Telnet) connection.
3-1 Using the Access Point Manager
Installed on your Windows 95/98/NT/2000 desktop computer, the Windows-based utility
“Access Point Manager” provides a user-friendly interface. The Access Point Manager
enables you to configure all of your Access Points on the network more easily than ever
before. The following gives instructions guiding you through the installations of the
Access Point Manager utility.
1. Insert the Software and Documentation CD into the CD-ROM drive, or the floppy disk
that came with your product kit into the floppy drive on your computer.
2. From the Start menu on the Windows desktop, choose Run.
3. In the Run dialog box, type the path where the utility is located, and click OK. For
floppy installation: A:\setup.
4. Follow the on-screen instructions to install the Access Point Manager.
5. Upon completion, go to Program Files and execute the Access Point Manager utility.
It will begin to browse all the Access Points available on the network.
6. Double click an Access Point icon to access its property dialog box. Enter the
password in the entry field. The default password is “default”.
7. After entering the correct password, a configuration window appears. You will see the
basic information of the Access Point, such as MAC Address, Frequency Domain and
Firmware Version.
MAC Address: It is a hardware identification number that distinguishes the unit from
others. You will see the number on the label located on the bottom of the access point.
Frequency Domain: The regulated operating frequency per country.
Firmware Version: Displays the firmware version that is equipped with your hardware.
Statistics
The statistics tab contains three of the following items for you to monitor the Ethernet
and Wireless network traffic.
Ethernet:
You may monitor the TX/RX on the wired network.
Wireless:
You may monitor the TX/RX of the wireless network.
Wireless Error:
This item offers detailed information on error wireless packets that the AP receives and
transmits.
Receive:
Packet FCS Errors: The number of wireless packets that fail during FCS transmission
(Frame Check Status when accessing the wired network.
No Buffer: The number of wireless packets that the AP ignores due to insufficient
memory.
Received WEP Errors: The number of wireless packets that have WEP encryption errors.
Transmit:
Deferred Transmission: The number of packets that have deferred transmission due to the
fact that the medium is busy.
Retry Limit Exceed: The number of packets that are not sent due to the reason that the
packets exceed the retry limits.
Single Tries: The number of packets that are successfully sent on the first retry.
Multiple Retries: The number of packets that are successfully sent after several retries.
Wrong Source Address: The number of packets that are ignored by the Access Point
because the source client is not in its BSS.
Other reasons: Other reasons that cause errors.
Configuration
The configuration tab contains 5 following items for you to make changes for the Access
Point.
General:
AP name: In this entry field, you may enter any name. This will enable you to manage
your Access Points with more ease if you have multiple Access Point on the network.
IEEE802.11:
Radio mode: You may select the operation mode for your Access Point.
Wireless LAN Access Point (AP): Served as a transparent Media Access Control (MAC)
bridge between wired and wireless network.
Inter-Building with Repeating (PxP): Connect several separated networks with Access
Points. (To be available soon)
Station Adapter – Infrastructure (SAI): Served as a wireless station (infrastructure).
Connected to a PC, it is able to access the network via Access Point.
Station Adapter – Ad-hoc (SAA): Served as a wireless station (Ad-hoc). Connected to a
PC, this station adapter along with other wireless stations can establish a small wireless
network without Access Points.
Station Adapter – 802.11 Ad-Hoc (SAA2): Same to SAA. This Ad-Hoc mode complies
with 802.11 standard.
NOTE: When setting the operation mode to either PxP or SAA, you need to set the
Access Points with the same channel. ESSID however can be ignored. When the SAA2
is selected, you need to set both the ESSID and channel for the Access Point.
ESSID: The ESSID is a unique ID given to the Access Point. Wireless clients associating
to the Access Point must have the same ESSID. The ESSID can have up to 32 characters.
Channel: You may select any of the available channels as an operational channel for
your Access Point.
RTS Threshold: RTS Threshold is a mechanism implemented to prevent the “Hidden
Node” problem. “Hidden Node” is a situation in which two stations are within range of
the same Access Point, but are not within range of each other. Therefore, they are hidden
nodes to each other. When a hidden station starts data transmission with the Access Point,
it might not notice that the other station is already using the wireless medium. When
these two stations send data at the same time, they might collide when arriving
simultaneously at the Access Point. The collision will most certainly result in a loss of
messages for both stations. Thus, the RTS Threshold mechanism will provide the solution
to prevent data collisions. When the RTS is activated, the station and its Access Point
will use a Request to Send/Clear to Send protocol (RTS/CTS). The station will send an
RTS to the Access Point, informing that it is going to transmit the data. Upon receipt, the
Access Point will respond with a CTS message to all station within its range to notify all
other stations to defer transmission. It will also confirm to the requesting station that the
Access Point has reserved the channel for transmission.
Fragmentation Threshold: Fragmentation mechanism is used for improving the
efficiency when there is high traffic within the wireless network. If you transmit large
files in a wireless network, you can enable the Fragmentation Threshold and specify the
packet size.
The mechanism will split the packet into the packet size you set.
TX Rate: When the Access Point is under PXP, SAI, SAA, and SAA2, it provides
various data rate options for you to select. Data rates options include Fully Auto, Fixed
1Mb/s, Fixed 2Mb/s, Auto Select 1M or 2M, Fixed 5.5Mb/s, and Fixed 11Mb/s. In most
networking scenarios, you will see that the factory-set default “Fully Auto” will prove the
most efficient. This setting will allow your 11Mbps Wireless LAN Access Point to
operate at the maximum data rate as possible. When the communications quality drops
below a certain level, the Access Point will automatically switch to a lower data rate.
Transmission at lower data speeds is usually more reliable. However, when the
communications quality improves again, the 11Mbps Wireless LAN Access Point will
gradually increase the data rate again, until it has reached the highest available transmit
rate.
Administration:
You may change the default password by entering the new password. Enter the new
password in the Confirm Change field to make the new setting take affect.
IP Address:
In the IP Address tab, there are two TCP/IP modes for the Wireless Access Point:
Bridge-Only and IP Router.
Bridge-Only To enable remote access to the Wireless Access Point using Telnet or Web
Management, you need to select the Bridge-Only mode and assign an IP address to the
wireless Router. You may either give a fixed IP address to your Wireless Access Point by
choosing the Manual item, or set your wireless Access Point to function as DHCP client
with the DHCP item selected. It will obtain the IP address automatically from your
DHCP server.
IP Router
In the IP Router mode, the Wireless Micro Access Point not only acts the bridge but also
manages the IP routing with Ethernet port and Wireless LAN port. For example, the
Ethernet port of the Wireless Router is connected to your enterprise TCP/IP network (or
WAN with Cable/DSL modem) while all the wireless clients being connected with its
own IP sub-network. The wireless clients can have private IP addresses and access the
Internet by sharing the IP address of Ethernet port with NAT.
For further configuration on the IP Router mode, you need to configure the Ethernet Port
(WAN) and Wireless LAN Port by entering the Setup item.
Ethernet Port (WAN): The values refer to the outside network you connect to whenever
you access the Internet connection. When the IP Router mode is enabled, the Wireless
Access Point will act as a DHCP client and automatically obtain the IP address. You may
also assign a fixed IP address to your Wireless Access Point by choosing the Manual
item. If you wish to activate the IP sharing, check the NAT (IP Sharing) through this
port check box. Moreover, you may have the Wireless Access Point to bridge the nonTCP/IP traffic by checking the “Enable Bridge” check box.
PPPoE Setup
If you wish to have the Wireless Access Point connected to a Cable/DSL modem, you
will need to manage the PPPoE settings. Once the PPPoE is enabled, the Access Point
will get IP configuration through PPPoE regardless of the settings of Manual or DHCP
IP Address. When the IP Router mode is selected, the PPPoE will be enabled at the same
time (default value). Click the Setup button and set the User Name and Password
provided by your ISP. Click Apply to make the changes take effect. The Wireless Access
Point will then automatically obtain an IP address from the PPPoE server and establish a
connection. The wireless clients will be able to access Internet via the Wireless Access
Point. To disconnect the link, click on the Disconnect button. If you want to re-start a
connection, click on the Connect button. With Connect on Demand checked, together
with defined Max. Idle Time, the PPPoE connection will be automatically disconnected
when the Wireless Access Point does not transmit or receive data within the specified idle
time.
Wireless LAN port: These values refer to your internal network settings. Unless you have
specific internal needs, there should be no reason to change these values. The default IP
Address is 192.168.1.1. If you wish to have the Wireless Access Point to act as a DHCP
server of the wireless clients, please enable the Enable DHCP server (wireless LAN)
check box and configure some network parameters such as IP Address Start, IP Address
End, DNS server, etc. For other network parameters such as Netmask, Gateway, DNS
10
server, WINS server, you may either choose to set manually or obtain these parameter via
your DHCP server.
WEP:
The 11Mbps Wireless Access Point allows you to create 4 data encryption keys to secure
your data from being eavesdropped by unauthorized wireless user. To activate and set the
WEP keys, do the following:
From the WEP encryption item, pull down the menu and it will list three options:
Disable – Allows wireless adapters to communicate with Wireless Access Points
without any data encryption.
WEP40 – Requires wireless stations to use data encryption with 64-bit algorithm
when communicating with the Wireless Access Point.
WEP128 - Allows wireless clients to communicate with the Wireless Access Point
with data 128 Bit encryption algorithm.
When WEP40 is selected, type five alphanumeric characters in the range of “a-z”,
“A-Z” and “0-9” (e.g. MyKey) in the WEP Key 1 entry field. Alternatively, you may
enter 10 digit hexadecimal values in the range of “A-F” , “a-f” and “0-9”, preceded
by the characters “0x” values (e.g. 0x11AA22BB33).
When WEP128 is selected, enter 13 alphanumeric characters in the range of “a-z”,
“A-Z” and “0-9” in the WEP Key fields. Alternatively, you may enter 26 digit
hexadecimal values in the range of “A-F”, “a-f” and “0-9”, preceded by the characters
“0x” values (e.g. 0x00112233445566778899AABBCC).
Enter the 4 WEP keys in the Key 1, Key 2, Key 3 and Key 4 entry filed. Select one WEP
key as an active key before enabling use of encryption.
NOTE: The WEP key must be set up exactly the same on the Wireless Access Points as
they are on the wireless client stations. If you use Key 1 on the Wireless Access Point
and the value is (e.g. MyCar), the same must be assigned to Key 1 for all client stations.
Upgrade
This item is used for uploading the newest firmware of the Access Point. You may either
enter the file name in the entry field or browse the file by clicking the Open File button.
For information about the release of the newest firmware, contact your local reseller.

Chapter 4 Troubleshooting
If you have trouble using the 11Mbps Wireless LAN Access Point, the starting point to
troubleshoot the problem with your Access Point is looking at the LED activity of the
Access Point. The following is “LED Error Table” provided to assist you in diagnosing
and solving operational problems.

If you are still unable to solve the problem by checking the LED activity, the error may
be caused from configuration mismatch, which prevents the Access Point from
establishing a wireless connection with the network. You may check the following to
ensure normal operation of the Access Point.
WEP keys: If data encryption is activated, always remember to set WEP keys exactly
the same on the Access Point as are on the wireless stations.
Access Control: Make sure that the MAC address of your Access Point is not included
in the Access Control table of other wireless devices.
Appendix A Tutorial on Network Configuration
The 11Mbps Wireless LAN products support the same network configuration options of
the legacy Ethernet LANs as defined by IEEE 802 standard committee.
The 11Mbps Wireless LAN products can be configured as:
Ad-Hoc for departmental or SOHO LANs
Infrastructure for enterprise LANs
LAN-Interconnection for point-to-point link as a campus backbone.
A-1 Network Topology
Ad-Hoc
An Ad-Hoc wireless LAN is a group of computers, each equipped with one wireless
adapter, connected as an independent wireless LAN. Computers in a specific Ad-Hoc
wireless LAN must be configured at the same radio channel.
19
Ad-Hoc wireless LAN is applicable at a departmental scale for a branch or SOHO
operation.
Infrastructure
The 11Mbps Wireless LAN devices provide access to a wired LAN for wireless
workstations. An integrated wireless and wired LAN is called an Infrastructure
configuration. A group of wireless LAN PC users and an Access Point construct a Basic
Service Set (BSS). Each wireless-equipped PC in this BSS can talk to any computer in
the wired LAN infrastructure via the Access Point.
Infrastructure configuration will extend the accessibility of a wireless station to the wired
LAN. Multiple Access Points will allow roaming and it will increase the transmission
range. The Access Point is also able to forward data within its BSS. The effective
transmission range in an infrastructure LAN is doubled.

Appendix C Glossary
Access Point - An internetworking device that seamlessly connects wired and wireless
networks.
Ad-Hoc - An Ad-Hoc wireless LAN is a group of computers each with wireless adapters,
connected as an independent wireless LAN.
Backbone - The core infrastructure of a network. The portion of the network that
transports information from one central location to another central location where it is
off-loaded onto a local system.
Base Station - In mobile telecommunications, a base station is the central radio
transmitter/receiver that maintains communications with the mobile radio telephone sets
20
within range. In cellular and personal communications applications, each cell or
microcell has its own base station; each base station in turn is interconnected with other
cells’ base.
Bridge - An internetworking function that incorporates the lowest 2 layers of the OSI
network protocol model.
BSS - Stands for “Basic Service Set,” an Access Point and all the wireless clients that
associated with it.
ESS - Stands for “Extended Service Set.” More than one BSS can be configured as an
Extended Service Set. Mobile users can roam between BSS in an ESS.
Ethernet - A popular local area data communications network, originally developed by
Xerox Corp., which accepts transmission from computers and terminals. Ethernet
operates on 10 Mbps baseband transmission over shielded coaxial cable or over shielded
twisted pair telephone wire.
Infrastructure - An integrated wireless and wired LAN is called an Infrastructure
configuration.
PCMCIA - Personal Computer Memory Card International Association, which develops
standards for PC cards, formerly known as PCMCIA cards, are available in three “types”
which are about the same length and width as credit cards, but range in thickness from
3.3 mm (Type I) to 5.0 mm (Type II) to 10.5 mm (Type III). These cards can be used for
many functions, including memory storage, landline modems and wireless modems.
Roaming - A wireless clients around an ESS and get the continuous connection to the
Infrastructure network.
RTS Threshold – Transmitters contending for the medium may not hear each other.
RTS/CTS mechanism can solve this “ Hidden Node Problem”. If the packet size is
smaller than the preset RTS Threshold size, the RTS/CTS mechanism will NOT be
enabled.
Web Management - Network management by using web browser connecting to the
target devices.
