should be the same.

11
Parameter Description
Tx Rate There are several options including
Auto/1/2/5.5/11/6/9/12/18/24/36/48/54Mbps for you to select.
When the “Auto” is selected, the device will choose the most
suitable transmission rate automatically. The higher data rate you
designated in the network, the shorter distance is allowed
between the adapter and the wireless stations.
When the adapter works in 11b mode, the maximum data rate is
11Mbps so that there are only “Auto/1/2/5.5/11Mbps” options you
can select.
SSID The SSID (up to 32 printable ASCII characters) is the unique
name identified in a WLAN. The ID prevents the unintentional
merging of two co-located WLANs.
You may specify a SSID for the adapter and then only the device
with the same SSID can interconnect to the adapter.
Any If “Any“ check box is enabled, the adapter will survey and connect
to one of the available wireless stations without checking the
consistency of channel and SSID with the wireless station.
Network Type Ad-Hoc – This mode enables wireless network adapters
interconnecting without through AP or Router. Select this mode if
there is no AP or Router in the network.
Infrastructure – This operation mode requires the presence of an
802.11 Access Point. All communication is done via the Access
Point or Router.
Change/Apply Clcik “Change“ will enable you to setup the parameters of
“General Connection Setting“. In the meantime, the button will
change to “Apply“ for you to confirm your settings.

3.3 WEP and WPA Encryption
WEP is an data encryption algorithm, which protects Wireless LAN data in the network
against eavesdropping. WEP has been found that it has some security problems. The
adapter supports WPA (Wi-Fi Protected Access) that combines IEEE 802.1x and TKIP
(Temporal Key Integrity Protocol) technologies. Client users are required to authorize before
accessing to Aps or AP Routers, and the data transmitted in the network is
encrypted/decrypted by a dynamically changed secret key. This adapter is also built-in AES
engine which ensure the highest degree of security and authenticity for digital information
and it is the most advanced solution defined by IEEE 802.11i for the security in the wireless
network.
3.3.1 WEP Setting
Parameter Description
Key Length You may select the 64-bit, 128-bit or 256-bit to encrypt
transmitted data. Larger key length will provide higher level of
security, but the throughput will be lower.
Default Key ID Select one of the keys (1~4) as the encryption key.
Key Format Hexdecimal – Only “A-F“, “a-f“ and “0-9“ are allowed to be set as
WEP key.
ASCII –Numerical values, characters or signs are allowed to be
the WEP key. It is more recognizable for user.

14
Parameter Description
Key1 ~ Key4 The keys are used to encrypt data transmitted in the wireless
network. Fill the text box by following the rules below.
64-bit – Input 10-digit Hex values or 5-digit ASCII values as the
encryption keys. For example: “0123456aef“ or “Guest“.
128-bit – Input 26-digit Hex values or 13-digit ASCII values as the
encryption keys. For example:
“01234567890123456789abcdef“ or “administrator“.
256-bit – Input 58-digit Hex values or 29-digit ASCII values as the
encryption keys.
Change/Apply Clcik “Change“ will enable you to setup the WEP key. In the
meantime, the button will change to “Apply“ for you to confirm
your settings.
3.3.2 WPA Setting
The adapter can automatically detect the WPA setting of the AP which the adapter intends
to connect to. To connect to the AP, you should setup the same setting with the AP.
There are two kinds of WPA mode: WPA and WPA-PSK. WPA is designed for enterprise
which requires a RADIUS Server and Certificate Server for the authentication. WPA-PSK is
a special mode designed for home and small business users who do not have access to
network authentication servers. In this mode, the user manually enters the starting
password in their access point or gateway, as well as in each wireless stations in the
network. WPA takes over automatically from that point, keeping unauthorized users that
don't have the matching password from joining the network, while encrypting the data
traveling between authorized devices.

15
Parameter Description
Connect Information It is the setting for WPA mode.
Protocol This adapter supports two kind of protocol for authentication
including TLS and PEAP. TLS and PEAP requires a certificate
which is provided by the Certificate Server. PEAP requires a set
of user name and password in addition. To get the certificate and
the personal user name and password, please contact with your
administrator.
TLS – Select a certificate from the “Certificate“ list.
PEAP – Input the “User Name“ and “Password“ and also select a
certificate from the “Certificate“ list.
User Name It is the setting for PEAP protocol.
Password It is the setting for PEAP protocol.
Pre-shared Key It is the setting for WPA-PSK mode. Input a 8 to 63 digits of ASCII
format to be the password for the authentication within the
network.
Certificate All the available certificates for TLS or PEAP will display in the
list. Please select a proper certificate for the wireless
authentication.
