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 depend 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.

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 Saving 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 performance.

EP-9321-g/g1
802.11g 54M Wireless LAN PCI Adapter

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.

4.1.1.3 Authentication & Security
Authentication Type: Defines authentication type of the wireless networks. The wireless adapter will need to
be set to the same authentication type to communicate. There are five options to choose as following:
Open System: With this setting any station in the Wireless LAN can associate with an Access Point to
receive and to transmit data. You can choose non-encryption or WEP encryption under Open System setting.
“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. There are four groups of WEP key you can set.

EP-9321-g/g1
802.11g 54M Wireless LAN PCI Adapter
20
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.

EP-9321-g/g1
802.11g 54M Wireless LAN PCI Adapter
21
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. You also can choose non-encryption or WEP encryption under Shared
setting.

EP-9321-g/g1
802.11g 54M Wireless LAN PCI Adapter

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
It’s 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
The IEEE 802.11b/g Wireless LAN standards subcommittee formulates standards for the industry. The
objective is to enable wireless LAN hardware from different manufacturers to communicate.
Infrastructure Mode
A client setting provides 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.

802.11g 54M Wireless LAN PCI Adapter
34
Roaming
The ability to use a wireless device is able to move from one access point range to another without losing the
connection.
RTS/CTS Threshold Value
It 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
It’s 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)
It’s 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.
