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 A202 adaptor’s 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 A202 automatically tunes in to the
access point channel. In Ad-hoc mode, you need to specify the channel
to use.
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 the data transfer rate to 54, 48, 36, 24, 18, 12, 11, 9, 6, 5.5, 2 and 1
Mbps.
Note: Operating the device at very high data rates reduces the operating
range. When the “Data Rate” is changed, the A202 will survey all available
APs and connect to the AP with the strongest signal.
Others. Click the WEP or Advanced link to open the Encryption or
Advanced property tab sheet.
A202 USB Wireless Key Adaptor
3-7
Encryption tab
Wireless data transmissions
between your A202 and an Access
Point are secured using Wired
Equivalent Privacy (WEP)
encryption. Choose the WEP
enabled option in the Data
encryption drop-down menu 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 in 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.

Chapter 3: Software support
WPA-PSK Encryption (Windows XP only)
This is a high level of security that only allows users with the correct
Wireless Network Key access to the wireless network, and is only
available to systems running Windows XP. To set up your A202
Wireless USB Key Adaptor:
1. Click on the Config button on the left-hand side of the Wireless
Settings window, then click on the Encryption tab at the top of the
window.
2. Set Network Authentication to WPA-PSK
3. Set Data Encryption to TKIP
4. Enter your Wireless Network Key into the text box. The wireless
network key, which is also referred to as the Passphrase Key in
some cases, is assigned within the Gateway/Router’s wireless
settings.
Once these settings have been entered, click the Apply button on
the left-hand side of the window.
A202 USB Wireless Key Adaptor
3-9
•
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 Initialization Vector assigned by the
wireless LAN adapter. 104-bit and 128-bit WEP keys 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 A202.
•
Keep a record of the WEP encryption keys.
3.2.3 Site Survey
The Site Survey window displays
the available networks within the
A202’s range, as well as 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 dBm.
Security - shows whether a network has WEP encryption enabled (On)
or disabled (Off).
Select an available network and click Connect to establish connection.

I cannot connect to an
Access Point (AP).
• Check if the Network Type of the
device is set to Infrastructure mode.
• Check if the device has the same
Service Set Identifier (SSID) as that of
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.
• Check if the MAC address of the device
is included in the AP Authorisation
Table. Ask your LAN administrator
about this.
• There is poor signal reception. Shorten
the distance between the A202 and the
access point.
I can connect to an
Access Point but I
cannot connect to the
Internet.
• Check if the A202 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.
I cannot connect to

• Check if the A202 has the same
Service Set Identifier (SSID) and
Channel as that of the other client.
• There is poor signal reception. Shorten
the distance between the device and

Action
I cannot connect to other
computers linked via an
Access Point or Ad-hoc
network.
• Check if the A202 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 AP/s 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.
I always have poor link
quality and low signal.
Do the following to achieve better link
quality and stronger signal:
• Keep the A202 away from devices that
generate a radio signal (such as
microwave ovens), and also large
metal objects to avoid radio
interference.
• Shorten the distance between the
device and the Access Point.
