3.2.2 Configuration
Basic tab
The Basic tab provides general
information on network types and
other configurations.
Network Type. Select the type of
network that you wish to use. Select
Infrastructure mode to establish a
connection with an access point (AP).
In this mode, your system can access
wireless LAN and wired LAN
(Ethernet) via the AP. Select the
Ad-Hoc mode to communicate
directly with other mobile clients within the Wireless LAN adaptor range.
Network Name - Displays the network SSID. The network SSID is a string
used to identify a wireless LAN. Assign different SSIDs to segment the
wireless LAN and increase network security. Set the SSID to a null string
to allow your station to connect to any available access point. A Null string
may not be used in Ad-hoc mode.
Channel. In Infrastructure mode, the wireless USB adaptor automatically
tunes in to the access point channel. In Ad-hoc mode, select a channel
that is allowed for use in your country/region.
Data Rate. Sets the data transmission rate to Fix or Auto. Select Fully Auto to
allow the device to adjust to the most suitable connection. You may also fix
data transfer rates to 54, 48, 36, 24, 18, 12, 11, 9, 6, 5.5, 2 and 1 Mbps.
Operating the device at very high data rates reduces the operating
range.
PS Mode. This field allows control of the Wireless USB adaptor power
saving features. The CAM (Constantly Awake mode) is recommended for
systems running on AC power. Other options include MAX_PSP
(Maximum power savings) and Fast_PSP (Fast power-saving mode)
Others. Click the WEP or Advanced link to open the Encryption or
Advanced property tab sheet.
Diamond Digital A101 Wireless USB Adaptor
3-7
Encryption tab
Wireless data transmissions
between your Wireless LAN
adaptor and the AP are secured
using the Wired Equivalent Privacy
(WEP) encryption. Check the Data
encryption (WEP enabled) option
to assign the WEP keys.
Check the Network Authentication
(Shared Mode) option if you wish to use
a network key to authenticate a
preferred wireless network. Unchecking
this option allows the network to operate on an Open System mode.
Key Format allows you to set a hexadecimal digit or ASCII character WEP key.
Key Length allows you to choose 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.
All wireless clients in a network must have identical WEP keys to
communicate with each other or with an access point.
Two ways to assign WEP keys
Manual Assignment. For a 64-bit encryption, enter 10 hexadecimal digits
(0~9, a~f, A~F) or 5 ASCII characters in each of the four WEP keys. For
128-bit encryption enter 26 hexadecimal digits (0~9, a~f, A~F) or 13 ASCII
characters in each of the four WEP keys.
Automatic Generation. Type a combination of up to 64 letters, numbers,
or symbols in the Passphrase field. The Wireless Settings utility uses an
algorithm to generate four WEP keys based on the typed combination.
3-8
Chapter 3: Software Support
• 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 Initialisation Vector assigned by the
wireless LAN adaptor. 104-bit and 128-bit WEP keys also use the
same encryption method.
• After assigning the WEP keys, click APPLY to save and activate the
encryption. Manually assigned encryptions are more secure than
automatically generated encryptions.
• Use Manual Assignment instead of Automatic Generation if you are
not sure whether other wireless clients use the same algorithm as
that of the Wireless LAN adaptor.
• Keep a record of the WEP encryption keys.
3.2.3 Site Survey
The Site Survey window
displays the available networks
within the wireless LAN adaptor
range and the following network
settings.
BSSID - The IEEE MAC address
of the available wireless networks.
SSID - SSID (Service Set
Identifier) of the network.
CH - Direct sequence channel
used by the network.
RSSI - Received Signal Strength Indicator (RSSI) in dB..
Encryption - shows whether a network has enabled WEP encryption
enabled or disabled.

The communication quality is based on signal level and noise level
measurements. The higher the SNR, the better the connection quality.
Communication Quality. This indicates the communication quality of the
Basic Service Set to which the station is connected.
Signal Level. This line specifies the average signal level of the Basic
Service Set to which the station is connected.
Noise Level. Specifies the average noise level of the Frequency Channel
currently used for connection.
Throughput. The Throughput graph sends a specified number of data
packets to the remote host and calculates the average transmission rate in
megabits per second.
During the test, the Start button toggles to Stop. Click Start button to

enabled, set the same WEP keys for the
device and the AP.
• Check if the MAC address of the device
is added in the AP Authorisation Table.
Confirm this with your LAN
administrator.
• There is poor signal reception. Shorten
the distance between the device and the
access point.
• Check if the device and the AP have the
same Encryption. If WEP encryption is
enabled, set the same WEP keys for the
device and the AP.
• Make sure the network protocol
parameters (IP address, subnet mask,
gateway, and DNS) of your computer
are correctly set.
• Check the proxy settings of the web browser.
• Check if the Network Type of the device

• Check if the device and the other APs and/
or clients have the same Encryption. If
you enable WEP encryption, you must set
the same WEP keys for the device and the
other APs and/or clients.
• Check the TCP/IP settings (IP address,
subnet mask, gateway, and DNS) of your
computer.
• Enable file and printer sharing in each
client computer to allow file sharing.
Do the following to achieve better link
quality and stronger signal:
• Keep the device away from microwave
ovens and large metal objects to avoid
radio interference.
• Shorten the distance between the
device and the AP/station.
This warning mesage appears when you
plug the A101 Wireless USB Adaptor into
a USB 1.1 port.
• For Windows® XP users, you need to
upgrade your OS to Service Pack 1 to
add USB 2.0 support.
