7.6.2 Wireless Client Mode
Select Wireless Client in the Operation Mode field to display the screen as shown next. This
mode has the device act as wireless client to connect to a wireless network.
"
WPA, WPA2 and IEEE 802.1x wireless security are not available when you
use Wireless Client, Bridge or AP+Repeater mode.
Output Power
Management
Set the output power of the device in this field. If there is a high density of APs
within an area, decrease the output power of the device to reduce interference
with other APs.
The options are
Full , 50% , 25% , 12% and Min .
Data Rate
Management
Use this field to select a maximum data rate for the wireless connection(s). Please
note that this is a total rate to be shared by all of the device’s wireless connections.
Preamble
Type
Preamble is used to signal that data is coming to the receiver.
Short preamble increases performance as less time sending preamble means
more time for sending data. All IEEE 802.11b compliant wireless adapters support
long preamble, but not all support short preamble.
Select
Long preamble if you are unsure what preamble mode the wireless
adapters support, and to provide more reliable communications in busy wireless
networks.
Select
Dynamic to have the device automatically use short preamble when all
wireless clients support it, otherwise the device uses long preamble.
Note: The device and the wireless stations MUST use the same
preamble mode in order to communicate.
Super-G Mode Super-G mode provides higher speed transmissions than regular IEEE 802.11g.
The other device must also support super-G mode in order for the device to use it
for the wireless connection. This is available when you select a Wireless Mode
that includes IEEE 802.11g.
Turbo-G Mode Turbo-G mode provides higher speed transmissions than regular IEEE 802.11g or
super-G mode. The other device must also support turbo-G mode in order for the
device to use it for the wireless connection. This is available when you select a
Wireless Mode that includes IEEE 802.11g.
Turbo-G uses two channels bonded together in order to achieve its higher
transmission rates. This may cause interference with other APs in the area. The
Channel field is automatically fixed at 6 when you use turbo-G mode.
RTS/CTS
Threshold
Enter a value between 0 and 2346. The default is 2346 .
Fragmentation Enter a value between 256 and 2346. The default is 2346 . It is the maximum data
fragment size that can be sent.
