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

and radio channel regulated by the country where the user is
World Mode – Enable the country roaming function, the
adapter will follow the setting of the connecting AP
User Select – Disable the country roaming function, users
can select the country where they are located in. The channel
setting differs from country user selected.
Power Consumption Setting Continuous Access Mode (CAM) – The adapter will always
set in active mode.
Maximum Power-Saving Mode – Enable the adapter in the
power saving mode when it is idle.
Fast Power-Saving Mode – Enable the adapter in the power
saving mode when it is idle, but some components of the
adapter is still alive. In this mode, the power consumption is
larger than “Max“ mode.
Fragementation Threshold The value defines the maximum size of packets, any packet
size larger than the value will be fragmented. If you have
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. Minor change is recommended.
RTS / CTS Threshold Minimum packet size required for an RTS/CTS (Request To
Send/Clear to Send). For packets smaller than this threshold,
an RTS/CTS is not sent and the packet is transmitted directly
to the WLAN. Select a setting within a range of 0 to 2347
bytes. Minor change is recommended

An Ad Hoc wireless LAN is a group of computers, each with a WLAN adapter,
connected as an independent wireless LAN. Ad Hoc wireless LAN is
applicable at a departmental scale for a branch or SOHO operation.
A specific Ad Hoc LAN is called a Basic Service Set (BSS). Computers in a
BSS must be configured with the same BSSID.
Dynamic Host Configuration Protocol - a method in which IP addresses are
assigned by server dynamically to clients on the network. DHCP is used for
Addressing and requires a dedicated DHCP server on the network.
Direct Sequence Spread Spectrum
This is the method the wireless cards use to transmit data over the frequency
spectrum. The other method is frequency hopping. Direct sequence spreads
the data over one frequency range (channel) while frequency hopping jumps
from one narrow frequency band to another many times per second.
An Infrastructure configuration could also support roaming capability for mobile
workers. More than one BSS can be configured as an Extended Service Set
(ESS). Users within an ESS could roam freely between BSSs while served as
a continuous connection to the network wireless stations and Access Points
within an ESS must be configured with the same ESSID and the same radio

Users must be wired to the network at all times to gain access.
A gateway is a hardware and software device that connects two dissimilar
systems, such as a LAN and a mainframe. In Internet terminology, a gateway
is another name for a router. Generally a gateway is used as a funnel for all
traffic to the Internet.
Institute of Electrical and Electronics Engineers
An integrated 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.
The FCC and their counterparts outside of the U.S. have set aside bandwidth
for unlicensed use in the so-called ISM (Industrial, Scientific and Medical) band.
Spectrum in the vicinity of 2.4 GHz, in particular, is being made available
worldwide. This presents a truly revolutionary opportunity to place convenient
high-speed wireless capabilities in the hands of users around the globe.
Local Area Network (LAN)
A LAN is a group of computers, each equipped with the appropriate network
adapter card connected by cable/air, that share applications, data, and
peripherals. All connections are made via cable or wireless media, but a LAN
does not use telephone services. It typically spans a single building or campus.
A network is a system of computers that is connected. Data, files, and
messages can be transmitted over this network. Networks may be local or
wide area networks.

card is also referred to CardBus Adapter.
A protocol is a standardized set of rules that specify how a conversation is to
take place, including the format, timing, sequencing and/ or error checking.

the same SSID are able to communicate with each other. This string is
Simple Network Management Protocol (SNMP)
Simple Network Management Protocol is the network management protocol of
TCP/IP. In SNMP, agents-which can be hardware as well as software-monitor
the activity in the various devices on the network and report to the network
console workstation. Control information about each device is maintained in a
structure known as a management information block.
Static IP Addressing
A method of assigning IP addresses to clients on the network. In networks with
Static IP address, the network administrator manually assigns an IP address to
each computer. Once a Static IP address is assigned, a computer uses the
same IP address every time it reboots and logs on to the network, unless it is
Transmission Control Protocol / Internet Protocol (TCP/IP)
TCP/IP is the protocol suite developed by the Advanced Research Projects
Agency (ARPA). It is widely used in corporate Internet works, because of its
superior design for WANs. TCP governs how packet is sequenced for

to the entire suite of related protocols.
