Auth./Encyp.
Authentication You MUST select the option to match the Wireless LAN you
wish to join. The available options are:
• Open - Broadcast signals are not encrypted. This method can
be used only with no encryption or with WEP.
• Shared - Broadcast signals are encrypted using WEP. This
method can only be used with WEP.
• LEAP - Light Extensible Authentication Protocol is a pre-
EAP, Cisco-proprietary protocol. If selected, you have to en-
ter the identity, password and domain name of your
computer.
• WPA - This version of WPA requires a Radius Server on
your LAN to provide the client authentication according to
the 802.1x standard. Data transmissions are encrypted using
the WPA standard.
• WPA-PSK - PSK means "Pre-shared Key". You must enter
this Passphrase value; it is used for both authentication and
encryption.
• WPA2 - This version of WPA2 requires a Radius Server on
your LAN to provide the client authentication according to
the 802.1x standard. Data transmissions are encrypted using
the WPA2 standard.
• WPA2-PSK - This is a further development of WPA-PSK,
and offers even greater security. You must enter this Pass-
phrase value; it is used for both authentication and
encryption.
• WPA None - If selected, you can only set encryption and
WPA-Preshared Key settings.
USB Wireless-G Adapter User Guide
14
Encryption The available options depend on the Authentication method
selected above. The possible options are:
• None - No data encryption is used.
• WEP - If selected, you must enter the WEP data shown
below. This WEP data must match the Access Point or other
Wireless stations.
• AES, TKIP - These options are available with WPA-PSK,
WPA2-PSK, WPA and WPA2. Select the correct option.
Use 802.1x This setting only takes effect when using Open, Shared, WPA or
WPA2 mode. If enabled, click the 802.1x tab to configure the
related settings.
WPA Preshared Key For WPA-PSK and WPA2-PSK modes, you need to enter the
desired value (8~63 characters). Data is encrypted using a 256Bit
key derived from this key. Other Wireless Stations must use the
same key.
WEP Key (1~4) This setting is only available for Open or Shared mode.
There are 2 modes:
• Hex - Only "A~F", "a~f", and "0~9" are allowed to be
entered.
• ASCII - Numerical values, characters or signs are all al-
lowed to be entered.
Using the Windows Utility
15
802.1x
EAP Method There are 5 methods in the drop-down list.
• PEAP - Protect Extensible Authentication Protocol. PEAP
transport securely authentication data by using tunneling be-
tween PEAP clients and an authentication server. PEAP can
authenticate wireless LAN clients using only server-side cer-
tificates, thus simplifying the implementation and
administration of a secure wireless LAN.
• TLS-Smart Card - Transport Layer Security. Provides for
certificate-based and mutual authentication of the client and
the network. It relies on client-side and server-side certifi-
cates to perform authentication and can be used to
dynamically generate user-based and session-based WEP
keys to secure subsequent communications between the
WLAN client and the access point.
• TTLS - Tunneled Transport Layer Security. This security
method provides for certificate-based, mutual authentication
of the client and network through an encrypted channel. Un-
like EAP-TLS, EAP-TTLS requires only server-side
certificates.
• EAP-FAST - Flexible Authentication via Secure Tunneling.
It was developed by Cisco. Instead of using a certificate, mu-
tual authentication is achieved by means of a PAC (Protected
Access Credential) which can be managed dynamically by
the authentication server. The PAC can be provisioned (dis-
tributed one time) to the client either manually or
automatically. Manual provisioning is delivery to the client
via disk or a secured network distribution method. Automatic
provisioning is an in-band, over the air, distribution.
• MD5-Challenge - Message Digest Challenge. Challenge is
an EAP authentication type that provides base-level EAP
support. It provides for only one-way authentication - there is
no mutual authentication of wireless client and the network.
Tunnel Authentica-
tion Select the desired option from the drop-down list.
Session Resumption After reconnecting the signal which broke up, you can enable the
session resumption to reduce the transferring packet to accelerate
the speed.
Authentication ID /
Password Enter the required data into the fields.
Tunnel ID / Password Enter the ID and Password for the tunnel.
Use Client certificate Click the checkbox to enable certificate authority server function.
Use certificate chain When the EAP authentication type such as TLS, TTLS or PEAP
is selected and required a certification to tell the client what
server credentials to accept from the authentication server in
order to verify the server, you have to enable this function and
enter the required data in the related fields.

Enable Tx Burst Tx Burst enables the adapter to deliver better throughput during a
period of time but the function only takes effect when connecting
with the AP which also supports Tx Burst.
Enable TCP
Window Size The TCP Window is the amount of data which a sender can send
on a particular connection before it gets an acknowledgement back
from the receiver that it has gotten some of it. When the router or
AP which the adapter is connecting to has set up the TCP Window,
you can enable the parameter to meet the data size for the router or
AP connection. The larger TCP Window the better performance.

try Region Code There are 8 kinds of Country Region Codes to choose from.
Enable CCX (Cisco
Compatible
eXtensions)
CCX (Cisco Compatible Extensions) is developed by Cisco for the
radio monitoring and fast roaming.
• Turn on CCKM: During normal operation, LEAP-enabled
client devices mutually authenticate with a new access point by
performing a complete LEAP authentication, including com-
munication with the main RADIUS server. When you
configure your wireless LAN for fast re-association, however,
LEAP-enabled client devices roam from one access point to
another without involving the main server. Using Cisco Cen-
tralized Key Management (CCKM), an access point configured
to provide Wireless Domain Services (WDS) takes the place of
the RADIUS server and authenticates the client so quickly that
there is no perceptible delay in voice or other time-sensitive
applications.
• Enable Radio Measurement: When this parameter is enabled,
the Cisco AP can run the radio monitoring through the asso-
ciated CCX-compliant clients to continuously monitor the
WLAN radio environment and discover any new Aps that are
transmitting beacons.

Appendix B
About Wireless LANs
This Appendix provides some background information about using Wireless
LANs (WLANs).
Modes
Wireless LANs can work in either of two (2) modes:
• Ad-hoc
• Infrastructure
Ad-hoc Mode
Ad-hoc mode does not require an Access Point or a wired (Ethernet) LAN. Wireless Sta-
tions (e.g. notebook PCs with wireless cards) communicate directly with each other.
Infrastructure Mode
In Infrastructure Mode, one or more Access Points are used to connect Wireless Stations
(e.g. Notebook PCs with wireless cards) to a wired (Ethernet) LAN. The Wireless Stations
can then access all LAN resources.
Access Points can only function in "Infrastructure" mode,
and can communicate only with Wireless Stations which are
set to "Infrastructure" mode.
BSS/ESS
BSS
A group of Wireless Stations and a single Access Point, all using the same ID (SSID), form a
Basic Service Set (BSS).
Using the same SSID is essential. Devices with different SSIDs are unable to communicate
with each other.
ESS
A group of Wireless Stations, and multiple Access Points, all using the same ID (ESSID), form
an Extended Service Set (ESS).
Different Access Points within an ESS can use different Channels. In fact, to reduce interfe-
rence, it is recommended that adjacent Access Points SHOULD use different channels.
As Wireless Stations are physically moved through the area covered by an ESS, they will
automatically change to the Access Point which has the least interference or best performance.
This capability is called Roaming. (Access Points do not have or require Roaming capabilities.)
B
Appendix B - About Wireless LANs
29
Channels
The Wireless Channel sets the radio frequency used for communication.
• Access Points use a fixed Channel. You can select the Channel used. This allows you to
choose a Channel which provides the least interference and best performance. In the USA
and Canada, 11 channels are available. If using multiple Access Points, it is better if adja-
cent Access Points use different Channels to reduce interference.
• In "Infrastructure" mode, Wireless Stations normally scan all Channels, looking for an
Access Point. If more than one Access Point can be used, the one with the strongest signal
is used. (This can only happen within an ESS.)
• If using "Ad-hoc" mode (no Access Point), all Wireless stations should be set to use the
same Channel. However, most Wireless stations will still scan all Channels to see if there
is an existing "Ad-hoc" group they can join.
WEP & WPA-PSK
Both WEP and WPA-PSK are standards for encrypting data before it is transmitted.
This is desirable because it is impossible to prevent snoopers from receiving any data which is
transmitted by your Wireless Stations. But if the data is encrypted, then it is meaningless
unless the receiver can decrypt it.
WPA-PSK is a later standard than WEP, and is more secure.
WPA2-PSK
This is a later version of WPA (WPA-PSK). The major change is the use of AES (Advanced
Encryption System) for protecting data. AES is very secure, considered to be unbreakable. The
PSK (Pre-shared Key) must be entered on each Wireless station.
If WPA2-PSK is used, the Wireless Stations and the Access Point must have the same
settings for each of the following:
WPA2 PSK
(Pre-shared Key) Enter the same value on every station and the AP. The PSK
must be from 8 to 63 characters in length. The 256Bit key
used for the actual encryption is derived from this key.
Encryption The same encryption method must be used. The most
common encryption method is TKIP. Another widely-
supported method is AES.
USB Wireless-G Adapter User Guide
30
Wireless LAN Configuration
To allow Wireless Stations to use the Access Point, the Wireless Stations and the Access Point
must use the same settings, as follows:
Mode On client Wireless Stations, the mode must be set to "Infrastructure".
(The Access Point is always in "Infrastructure" mode.)
SSID (ESSID) Wireless Stations should use the same SSID (ESSID) as the Access
Point they wish to connect to. Alternatively, the SSID can be set to "any"
or null (blank) to allow connection to any Access Point.
Security The Wireless Stations and the Access Point must use the same settings
for Wireless security (Disabled, WEP, WPA-PSK, WPA2-PSK, WPA,
WPA2)
• If Wireless security remains disabled on the Access Point, all
stations must have wireless security disabled.
• If Wireless security is enabled on the Access Point, each station
must use the same settings.
