Ø Transmit Rate:
You can choose one of the transmission rates as follows, 54Mbps, 48Mbps,
36Mbps, 24Mbps, 22Mbps, 18Mbps, 12Mbps, 11Mbps, 9Mbps, 6Mbps, 5.5Mbps,
2Mbps, 1Mbps, Fully Automatic and Turbo Mode.
In some specific wireless devices, the transmit rate can define up to 72Mbps for
802.11g, select the Turbo Mode function to enhance the transfer rate of the wireless
connection.
The Fully Automatic and Turbo Mode will automatically detect the suitable linking
transfer rate and auto fall back when the signal is not too strong to transmit data.
Ø Power Saving:
To set your Wireless Cardbus Adapter as power saving mode, select “Off”,
“Normal” or “Maximum”.
Ø Transmit Power:
By selecting the Transmit Power, you can select the Radio Frequency output power
from Minimum, 12.5%, 25%, 50%,100% or Auto.
Ø Preamble Type:
The usage of the preamble is to limit the packet size of the data to transmit. It is
recommended to choose the short preamble when the link quality is bad, it is to
prevent the wasting time of resending a long packet that is lost. The Default is Auto
which access short and long preamble.
Ø Authentication Type:
Open System: with the same WEP key between the stations, the stations don’t
need to be authenticated, and this algorithm was set to default.
Shared Key: with the same WEP key between the stations in this Authentication
algorithm, this type will use packets with encryption by transferring a challenge
text which will be acknowledge by both side of the stations. In order to choose
which authentication algorithm will be used, you must know which one the station
supports this algorithm first.
Ø Country Domain:
This is the channel selection of each country regulatory domain, select the country
where you are using this wireless device, users are responsible for ensuring that the
channel set configuration is in compliance with the regulatory standards of these
countries.
Ø Fragment Threshold:
Fragmentation Threshold is a way of transmitting the packets that will be
fragmented. Choose a setting within a range of 256 to 2432. It is recommended to
fragment the packet when the link quality is bad, it is to prevent the wasting time of
resending a long packet that is lost.
Ø RTS/CTS Threshold:
The RTS/CTS Threshold is a station initiates the process by sending a RTS frame,
the other ends receives the RTS and responds with a CTS frame, the station must
receive a CTS frame before sending the data frame. This is to prevent the collisions
by each station. Choose a setting within a range of 256 to 2432. It is recommended
limiting a long packet to prevent each station waiting too long to transmit a data.
