After the Configuration Utility has been installed, an icon will placed in the system tray when the WLAN USB Adapter
is inserted. Click the icon and the configuration utility will pop up.
The utility was six tabs: Profile, Link Status, Site Survey, Statistics Advance, and About. You should change all your
configuration settings for your WLAN USB Adapter using this utility.
4.1.1 Profile
15
Specific different network profile settings used in various locations, such as your office, your home, the factory, or the
airport. In each profile, you can specify a network type, network name, WEP and security setting parameters required
for that operating location.
4.1.1.1 System Configuration Edit profile Network Type:
The column in Profile list from left to right is “Profile”、”SSID”、”Channel”、”Authentication”、”Encryption”and
“Network Type” .Click ACTIVATE to excuse the profile.
16
SSID: All wireless devices within the ESS or extended wireless LAN use the SSID. This can be any alphanumeric
value of up to 32 characters long. Use this to prevent cross communication between two or more WLAN in one area.
The SSID should be changed in order to provide some minimum security.
Channel: Shows the selected channel that is currently used. (Available channels depends on the country or region
you are located.)
Authentication: Defines authentication type of the wireless networks, including "Open System" and “Share Key”
authentication. The wireless adapter will need to be set to the same authentication type to communicate.
Encryption: Indicates your WEP (Wired Equivalent Privacy) settings. WEP encryption can be used to ensure the
security of your wireless network. If there is no Encryption exists, the column will show Not USE.
Network Type: The network type of the wireless network. An Ad-Hoc wireless LAN is a group of computers each
with wireless adapters, connected as an independent wireless LAN. An integrated wireless and wired LAN is called an
infrastructure configuration.
17
4.1.1.2 Edit Profile
To add a new location profile name or to rename, delete, or select an existing profile, click Edit. The Edit
Configurations screen appears as follows
Power Save Mode:
CAM: (Constant Awake Mode) CAM is the normal mode for desktop machines or other machines where power
consumption is not an issue. It keeps the radio powered up continuously, so there is little latency for responding to
messages.
Max_PSP: Maximum Power Save.
Fast_PSP: Fast Awake.
Network Type
The network type of the wireless network. An Ad-Hoc wireless LAN is a group of computers each with wireless
adapters, connected as an independent wireless LAN. An integrated wireless and wired LAN is called an infrastructure configuration.
Preamble Type
Preamble is the first sub-field of PPDU, which is the appropriate frame format for transmission to PHY (Physical
layer). There are two options, Short Preamble and Long Preamble. The Short Preamble option improves throughput
18
performance.
RTS Threshold: The RTS Threshold sets an upper threshold at which point the device will issue an RTS packet. The
RTS (Request To Send) packet is used for the purpose of avoiding data collisions on the wireless LAN. There are
several trade offs to consider when setting this parameter. Setting this parameter to a small value causes RTS packets
to be sent more often, consuming more of the available bandwidth, therefore reducing the apparent throughput of other
network packets. However, the more often RTS packets are sent, the quicker the system can recover from interference
or collisions. Refer to the IEEE 802.11 Standard for more information on the RTS/CTS mechanism.
Fragment Threshold: Fragment Threshold defines a threshold above, which the wireless packet will be split up, or
fragmented. For a fragmented packet, if transmission of part of it were to be interfered with, only the portion that was
successfully transmitted would need to be resent. Throughput will generally be lower for fragmented packets, since the
fixed packet overhead consumes a higher portion of the RF bandwidth.
19
4.1.1.3 Authentication & Security
Authentication Type: Defines authentication type of the wireless networks, including "Open System" and “Share Key”
authentication. The wireless adapter will need to be set to the same authentication type to communicate.
Open System: With this setting any station in the Wireless LAN can associate with an Access Point to receive and to
transmit data.
Share Key: Is when both the sender and recipient share a secret key. Both units use this key for an extended length of
time, sometimes indefinitely.
Encryption Type: Indicates your WEP (Wired Equivalent Privacy) settings. WEP is disabled by default.
WEP : WEP (Wired Equivalent Privacy) is an optional feature of the IEEE 802.11 standard that is used to ensure the
security of your wireless network.
No Encryption: No any encryption for security.
20
WEP Key:
Key 1 - Key 4: These four fields can be used to manually enter the encryption keys. This may be necessary if you wish
this node to match keys in a different vendor's product.
WEP Key length: The 64 or 128-bits Wired Equivalent Privacy Algorithm. You can decide the network key to be
encoded by ASCII characters or hexadecimal digitals. A key of 10 hexadecimal characters (0-9, A-F) is required if a
64-bit Key Length was selected. A key of 26 hexadecimal characters (0-9, A-F) is required if a 128-bit Key Length
was selected.
4.1.2 Link Status
You can see the below status:Status, Current Channel, Current TX Rate, throughput(Kbit/sec), Link Quality, Signal
Strength.

5. Glossary
Ad-Hoc Mode
An Ad-hoc integrated wireless LAN is a group of computers, each has a Wireless LAN adapter, Connected as an
independent wireless LAN. Ad hoc wireless LAN is applicable at a departmental scale for a branch or SOHO operation.
BSS ID
A specific Ad hoc LAN is called a Basic Service Set (BSS). Computers in a BSS must be configured with the same
BSS ID.
DSSS (Direct-Sequencing Spread-Spectrum)
DSSS operate over the radio airwaves in the unlicensed ISM band (industrial, scientific, medical). DSSS uses a
radio transmitter to spread data packets over a fixed range of frequency band.
Encryption
A security method that applies a specific algorithm to data in order to alter the data appearance and prevent other
devices from reading the information.
Firmware
Program that is inserted into programmable read-only memory (programmable read-only memory), thus becoming a
permanent part of a computing device.
Fragmentation Threshold Value
Indicates how much of the network resources is devoted to recovering packet errors. The value should remain at its
default setting of 2,432. If you experience high packet error rates, you can decrease this value but it will likely decrease
overall network performance. Only minor modifications of this value are recommended.
Fragmentation
Breaking a packet into smaller units when transmitting over a network medium that cannot support the original size
of the packet.
IEEE
The Institute of Electrical and Electronics Engineers
IEEE 802.11b/g standard
26
The IEEE 802.11b/g Wireless LAN standards subcommittee formulating standards for the industry. The objective is
to enable wireless LAN hardware from different manufacturers to communicate.
Infrastructure Mode
A client setting providing connectivity to an Access Point. As compared to Ad-Hoc Mode where PCs communicate
directly with each other clients set in
Infrastructure Mode all pass data through a central Access Point. The Access Point not only mediates Wireless network
traffic in the immediate neighborhood but also pro-vides communication with the wired network. An integrated wireless
and wireless and wired LAN is called an Infrastructure configuration. Infrastructure is applicable to enterprise scale for
wireless access to central database, or wireless application for mobile workers.
Roaming
The ability to use a wireless device and be able to move from one access point range to another without losing the
connection.
RTS/CTS Threshold Value
Should remain at its default setting of 2,347. A preamble is a signal used to synchronize the transmission timing
between two or more systems. A series of transmission pulses is sent before the data to indicate that someone is about
transmit data.?This ensures that systems receiving the information correctly when the data transmission starts.
Shared Key
Is when both the sender and recipient share a secret key. Both units use this key for an extended length of time,
sometimes indefinitely. Any eavesdropper that discovers the key may decipher all packets until the key is changed.
Signal Strength
The signal level indicates the strength of the signal as received at the wireless network interface.
SSID (Service Set Identifier)
Is the unique name shared among all points in a wireless network. The SSID must be identical for all points in the
network. It is case sensitive and must not exceed 32 characters.
WEP (Wired Equivalent Privacy)
A data privacy mechanism based on a 40 bit shared key algorithm, as described in the IEEE 802 .11 standard. The
optional cryptographic confidentiality algorithm specified by IEEE 802.11 used to provide data confidentiality that is
subjectively equivalent to the confidentiality of a wired LAN medium that does not employ cryptographic techniques to
enhance privacy.
WPA
Wi-Fi Protected Access, a specification to improve the security level of wireless networks. It uses 802.1x and EAP to
control network access. Temporal Key Integrity Protocol (TKIP) is used to secure data during transmission.
