 v2 User’s Guide

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.

Apply

Click Apply to save your changes back to the device.
