Prole Name: Dene easily recognizable prole names to identify the
different networks.
SSID: The SSID (up to 32 printable ASCII characters) is the unique name
identied in a WLAN. The ID prevents the unintentional merging of
two co-located WLANs. If you specify an SSID for the adapter, then
only the device with the same SSID can interconnect to the adapter.
To add a nearby network to the prole list, pull down the menu to view
all the networks that can be selected.
Power Save Mode: The two power-saving functions are available only
when Network Type (see below) is set to “Infrastructure.”
• CAM (Constantly Awake Mode): With this selected, the adapter
will remain in an active mode.
• PSM (Power Save Mode): Enable the adapter in the power-save
mode when it is idle.
Network Type: Select from the drop-down menu.
• Infrastructure: This operation mode requires the presence of an
802.11 access point. All communication is done via the AP or router.
• Ad-Hoc: Select this mode to connect to another wireless station in
the wireless LAN network without using an access point or router.
Tx Power: To lower the transmit power of the adapter to reduce the power
used by the system, select a lower percentage from the drop-down
menu. NOTE: A lower power level will result in lower signal strength
and reduced coverage range.
CONFIGURATION

RTS Threshold: This is the minimum packet size required for an RTS
(request to send). For packets smaller than this threshold, an RTS is
not sent and the packet is transmitted directly to the wireless network.
Select a setting within a range of 0 to 2347 bytes. NOTE: A minor
change is recommended.
Fragment Threshold: This value denes the maximum size of packets;
any packet size larger than the value will be fragmented. If you’ve
decreased this value and experience high packet-error rates, you
can increase it again, but it will likely decrease overall network
performance. Select a setting within a range of 256 to 2346 bytes.
NOTE: A minor change is recommended.
proFile authentiCation and enCryption (seCurity)
Authentication Type: This pull-down menu setting has to be consistent
with the wireless networks that the adapter is intended to connect.
• Open: No authentication is needed within the wireless network.
• Shared: Only wireless devices using a shared key (WEP key
identied) are allowed to connect to each other.
• LEAP: This is a pre-EAP, Cisco-proprietary protocol with many of
the features of EAP protocols. Cisco controls the ability of other
vendors to implement this protocol, so it should be selected for use
only when a limited vendor choice for client, access point and server
products is not a concern. When you’ve set up LEAP authentication,
you need to enter the username and password of your computer.
• WPA: WPA provides a scheme of mutual authentication using either
IEEE 802.1x/Extensible Authentication Protocol (EAP) authentication
13
CONFIGURATION

or pre-shared key (PSK) technology. It provides a high level of
assurance to enterprises, small businesses and home users that
data will remain protected and that only authorized users may access
their networks. For enterprises that have already deployed IEEE
802.1x authentication, WPA offers the advantage of leveraging
existing authentication databases and infrastructure.
• WPA-PSK: This is a special mode designed for home and small
business users who do not have access to network authentication
servers. In this mode, known as Pre-Shared Key, you manually
enter the starting password in your access point or gateway, as
well as in each wireless station in the network. WPA-PSK takes
over automatically from that point, keeping unauthorized users who
don’t have the matching password from joining the network, while
encrypting the data traveling between authorized devices.
• WPA2: Like WPA, WPA2 supports IEEE 802.1x/EAP authentication,
or PSK, technology. It also includes a new advanced encryption
mechanism using the Advanced Encryption Standard (AES). AES is
required for corporate or government users. The difference between
WPA and WPA2 is that WPA2 provides data encryption via AES. In
contrast, WPA uses the Temporal Key Integrity Protocol (TKIP).
• WPA2-PSK: This is also for home and small business use. The
difference between WPA-PSK and WPA2-PSK is that WPA2-PSK
provides data encryption via the AES. In contrast, WPA-PSK uses
the Temporal Key Integrity Protocol (TKIP).
• WPA-NONE: This is dened for Ad Hoc mode and behaves like
WPA-PSK (WPA-PSK is only dened for Infrastructure mode). The
user manually enters the Pre-Shared Key in each wireless station
in the network, and WPA-NONE controls unauthorized users who
don’t have the matching Pre-Shared Key from joining the network.
It also encrypts the data traveling between authorized devices.
802.1x Setting: When Authentication Type is set to “Open,” “Shared,”
“WPA” or “WPA2,” you can also enable IEEE 802.1x Setting to use the
authentication server or certication server to authenticate client users.
NOTE: See the two separate 802.1x Setting sections below for details.
Encryption: Select from the drop-down menu.
• None: Disables the encryption mode.
CONFIGURATION
14

• WEP: Enables the WEP Data Encryption. When the item is selected,
you need to continue setting the WEP Encryption keys.
• TKIP: The Temporal Key Integrity Protocol changes the temporal key
every 10,000 packets (a kind of message transmitted over a network.)
This ensures much greater security than the standard WEP security.
• AES: AES has been developed to ensure the highest degree of
security and authenticity for digital information. It’s the most advanced
solution dened by IEEE 802.11i for security in the wireless network.
NOTE: All devices in the network should use the same encryption
method to ensure the security of communications.
WPA Pre-Shared Key: The WPA-PSK key can be 8 to 64 characters in
length and can be letters or numbers. This same key must be used on
all the wireless stations in the network.
WEP Key (Key#1–4): WEP keys are used to encrypt data transmitted
in the wireless network. There are two types of key length: 64-bit and
128-bit. Assign a default encryption key (Key#1 to Key#4) by clicking
on the corresponding radio button. To ll in each text eld:
• 64-bit: Input 10-digit hex values (in the A-F, a-f and 0-9 range) or
5-digit ASCII characters (a-z and 0-9) as the encryption keys.
For example: “0123456aef“ or “test1.”
• 128-bit: Input 26-digit hex values (in the A-F, a-f and 0-9 range) or
13-digit ASCII characters (“a-z” and “0-9”) as the encryption keys.
For example: “01234567890123456789abcdef“ or “administrator.”
The IEEE 802.1X specication describes a protocol that can be used for
authenticating both clients (802.1x Setting/Certication below) and servers
(802.1x Setting/CA Server below) on a network. The authentication
algorithms and methods are those provided by the Extensible Authentication
Protocol (EAP), a method of authentication that has been in use for a
number of years on networks that provide Point-to-Point Protocol (PPP)
support (as many Internet service providers and enterprises do). EAP
runs before network layer protocols transmit data over the link.
When an AP acting as an authenticator detects a wireless station on the
LAN, it sends an EAP request for the user’s identity to the device. In
turn, the device responds with its identity, and the AP relays this identity
to an authentication server (typically an external RADIUS server).
CONFIGURATION
15

802.1xsetting/CertiFiCation
EAP Method: The EAP authentication protocols supported by this
adapter require that settings be consistent with the wireless access
points or routers that the adapter is intended to connect.
• PEAP & TTLS: These protocols are similar and easier to use than
TLS (below) in that they specify a stand-alone authentication protocol
to be used within an encrypted tunnel. TTLS supports any protocol
within its tunnel, including CHAP, MS-CHAP, MS-CHAPv2, PAP and
EAP-MD5. PEAP species that an EAP-compliant authentication
protocol be used; this adapter supports EAP-MSCHAP v2, EAP-TLS/
Smart Card and Generic Token Card. The client certicate is optional.
• TLS/Smart Card: This is the most secure of the EAP protocols, but
isn’t easy to use: It requires that digital certicates be exchanged in

Use certicate chain: When the Extensible Authentication Protocol
(EAP) authentication type — such as TLS, TTLS or PEAP — is
selected and requires certication to tell the client what credentials to
accept from the authentication server in order to verify the server, you
need to enable this function. Choose the preferred server from the
drop-down menu to issue the certicate. If “Any Trusted CA” is
selected, any CA (certication authority) on the list (which is provided
by the Microsoft Certicate Store) is permitted.

subordinate certication authorities are trusted only if they have a
valid certication path from a trusted root certication authority.
Server Name: Enter the authentication server name.
Server name must match exactly: When selected, the server name
must exactly match the server name found on the certicate.
Domain name must end in specied name: When this is selected,
the server name eld identies a domain. The certicate must use a
server name belonging to this domain or one of its sub-domains (e.g.,
zeelans.com, where the server is blueberry.zeelans.com), but it may
be any name used in the certicate name eld.

to this mode. This mode is also the default setting.
• 802.11 B only: Though the adapter is compatible with both 802.11g
and 802.11b wireless stations, if there are only 802.11b wireless
stations in the network, you can set the adapter to this mode.
Ad Hoc Wireless Mode: When the adapter is set in Ad Hoc (Peer to
Peer) mode, you can designate the wireless connection mode for the
Ad Hoc network.
• Only B: Though the adapter is compatible with both 802.11g and
802.11b wireless stations, if there are only 802.11b wireless stations
in the network, you can set the adapter to this mode.
• B/G Mixed: If you have a mix of 802.11b and 802.11g wireless
stations in your network, it is recommended that the adapter be set
to this mode. This mode is also the default setting.
• Only G: Though the adapter is compatible with both 802.11g and
802.11b wireless stations, if there are only 802.11g wireless stations
in the network, you can set the adapter to this mode.
Wireless Protection: If you have a mix of 802.11b and 802.11g wireless
stations in the network, it’s recommended that you enable the protection
mechanism, which can decrease the rate of data collisions between
802.11b and 802.11g wireless stations. When the protection mode is
enabled, the throughput of the adapter will be a little lower.
• Auto: Depending on the status of the network, this automatically
disables/enables the protection mode.
• On: Always enables the protection mode.
• Off: Always disables the protection mode.
CONFIGURATION

Tx Rate: There are several options in the drop-down menu: “Auto” and a
range of speeds from “1 Mbps” to “54 Mbps.” When “Auto” is selected,
the device automatically chooses the most suitable transmission rate.
The higher the data rate designated in the network, the shorter the
distance allowed between the adapter and the wireless stations.
Enable Tx Burst: This enables the adapter to deliver better throughput
in the same period and environment.
Enable TCP Window Size: The TCP window is the amount of data a
sender can deliver on a particular connection before it gets an
acknowledgment back from the receiver that it has gotten some of it.
When the router or AP 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 the TCP window, the better
the performance.
Fast Roaming at [-70] dBm: To fast roam to a nearby network without
interrupting the wireless connection (such as a multimedia application
or a voice call), you can set this parameter. The adapter will fast roam
when the receive sensitivity (signal strength) is below the value entered.
Show Authentication Status Dialog: Select to display.
Select Your Country Region Code: Channel availability varies from
country to country; for example, USA (FCC) channels are 1-11, while
Europe (ETSI) channels are 1-13.
Enable CCX: Cisco Compatible Extensions, for radio monitoring and
fast roaming.
Turn on CCKM: During normal operation, LEAP-enabled client devices
mutually authenticate with a new AP by performing a complete LEAP
authentication, including communication with the main RADIUS server.
When a wireless LAN is congured for fast re-association, however,
LEAP-enabled client devices roam from one access point to another
without involving the main server. Using Cisco Centralized Key
Management (CCKM), an access point congured 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.
