NTRODUCTION

ireless LAN (Local Area Network) systems offer a

number of greater excellences over a traditional wired

system. Wireless LANs (WLANs) are easier to setup and

manage, more flexible and often more cost effective than their

wired equivalence.

By using radio frequency (RF) technology, the need for wired

connections is minimized while WLANs transmit and receive data

over the air. Therefore, WLANs combine data connectivity and

user mobility through simplified configuration, enabling movable

LANs.

AOpen AOI-701U wireless LAN PC adapters allow notebook

users to access shared information without looking for a place to

plug in. It offers mobility and flexibility to the LAN users. In

addition to the easy installation, AOI-701U is compatible with

Window 95, 98, ME, NT, 2000, and XP.

NSTALLATION

Overview

Please follow these to establish your wireless network connection:

1. Install Access Point (AOI-706U) first, if the

infrastructure network is required.

2. Install the Driver CD.

3. Install the USB Wireless LAN Adapter (AOI-702U).

4. Install the network protocol(S) which is required for

networking communication on your network. (Most likely

you will need the TCP/IP protocol.)

Installation for Window 95/98/2000/ME/NT

Installation Procedure:

AOpen Wireless PC Adapter

1. Power on your computer with WINDOWS 95(OSR2)

/98/2000/ME/NT loaded

2. Make sure that there is no USB adapter inserted.

3. Insert the Installation CD. Go “USB” folder, and click on

the SETUP.

4. Click “Next>” to proceed the installation.

5. Click NEXT to confirm the destination that you would like

to save the files.

AOpen Wireless PC Adapter

6. Select a program folder that you would like to install the

program. The default folder is AOpen Wireless

LAN\AOI-702U. Once confirm, please click on NEXT.

7. Click NEXT to confirm all the default settings. The

default Operation Mode is Infrastructure mode, and the

default ESSID is aopen. You may change the default

setting afterwards. Please refer to Chapter 3 for

configurations.

ONFIGURATION

ireless LAN USB adapter (AOI-702U) comes with its own

management software. This utilities application is

provided and configured by you. After successful

installation of the adapter, a new icon, Wireless Configuration

Utility, should appear in your system tray (as figure 1). GREEN

means a good connection with strong signals. YELLOW means a

fair connection. RED means a poor connection or no signals at all.

Double clicking on that Configuration Utility icon, or go to

START -> PROGRAM ->AOPEN WIRELESS LAN

->AOI-702U -> CONFIGURATION UTILITY, you will enter

the Wireless Configuration Utility program. ( as figure 2).

Figure 1 Configuration Utility icon

Figure 2

Wireless Configuration Utility

program

The utility is divided into five tabs: STATUS, STATISTICS,

SITE SURVEY, ENCRYPTION, ADVANCED, AND

VERSION.

STATUS (see figure 2)

It shows the information of the linkage between this

wireless pc adapter and the wireless access point.

Click the CHANGE button to change the set ups, and click the

SUMIT button after the configuration has been changed.

Operation Mode

The Operation Mode setting determines the structure of your

wireless network. The default is Infrastructure mode.

AOpen Wireless PC Adapter

 Ad Hoc: The Ad-Hoc mode is for a simple peer-to peer

network. ( with no Access Point needed)

 Infrastructure: The infrastructure mode allows wireless

users to be able to access to the wired (existed) network by

using an Access Point. With Multiple access points, they

provide roaming, which extend the coverage of the wireless

network.

Channel

It specifies the channel used in wireless communication and should

be set to the same channel with other wireless nodes in the same

wireless network. The default channel is channel 6.

SSID (Service Set Identifier)

SSID is the unique name shared among all nodes in a wireless

network. The SSID must be the same for all the nodes on the

network, and is case sensitive. The default SSID is aopen.

TX Rate: This is the current transfer rate for the network card. It

should set to Fully Automatic to get the optimal performance

State

State is to display the current state of the linkage.

It shows the BSS ID of the associated Access Point which wireless

connects to the adapter. The state is showing “Scanning” when the

adapter is searching for an available access point. Sometimes it is

because the adapter can not detect the SSID for an access point

within the range. An error message may be displayed when the

driver failed to initialize.

Signal Strength

It is active only when the node is in Infrastructure Mode. Here

displays the signal strength of the connection.

AOpen Wireless PC Adapter

Link Quality

This is active only when it is in Infrastructure Mode. Here

displays the quality of the linkage between the adapter and the

Access Point.

Link Quality is a measurement of receiving and transmissions

errors. It will start looking for a better Access Point when the Link

Quality indication poor connection.

MAC Address

This unique 48-bit Media Access Control address is known as the

station identifier.

STATISTICS

It shows the total amount of packets which have been

received or transmitted by the adapter.

Figure 3

STATISTICS tab

Click the RESET button to reset the data.

AOpen Wireless PC Adapter

SITE SURVEY

It shows all the Access Points nearby when the

Infrastructure mode is chose, or all the nearby wireless

adapters when it is in the Ad Hoc mode.

Figure 4

SITE SURVEY tab

Click on RE-SCAN to search more available wireless devices near

by. You may double click on any Access Point(BSSID) to connect

automatically.

AOpen Wireless PC Adapter

ENCRYPTION

Figure 5 ENCRYPTION tab

An additional security measurement may be desired on protecting

your wireless network. This can be achieved by applying WEP

(Wired Equivalent Privacy) encryption. WEP uses a combination

of 64bit and 128bit keys to encrypt every data transmission.

Encryption (WEP)

It can be set to Disable, 64 Bit, and 128 Bit. Once enable the WEP,

you would create an encryption key. All the nodes in the same

wireless network need to present the identical key for the

communication.

Key 1 – Key 4

The Keys can be entered manually in these four fields and restored.

Default Tx Key

You may chose Key 1 to Key 4 as your default key.

Authentication Type

It is only used for WEP only. You may choose between Open

System or Shared Key.

AOpen Wireless PC Adapter

 Shared Key is when both sender and receiver share a secret

key.

 Open System is when both sender and receiver do not

share a secret key. It prevents the eavesdropping if the

secret key is discovered.

ADVANCED

Figure 6 ADVANCED tab

It allows you to set the Preamble Type, Fragmentation Threshold

and RTS/CTS Threshold.

Preamble Type

It should be set to Long for a “noisy” network environment, or

Short for a clear network environment.

Fragmentation Threshold

The lower value of the fragmentation threshold will increase the

AOpen Wireless PC Adapter

devotion to recovering packet errors, however at the same time, it

will also decrease the network performance.

RTS/CTS Threshold

The higher value of RTS/CTS threshold will increase better traffic

coordination of the wireless network.

VERSION

It shows the versions of the driver, firmware, and application

of AOI-702U.
