Table 28   Wireless: Advanced

Wireless Advanced Setup

RTS/CTS 

Threshold

Enter a value between 0 and 2432. 

Fragmentation 

Threshold

It is the maximum data fragment size that can be sent. Enter a value between 256 and 

2432. 

Preamble

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 Short preamble if you are sure the wireless adapters support it, and to provide 

more efficient communications.

Note: The Prestige and the wireless stations MUST use the same 

preamble mode in order to communicate.

802.11 Mode

Select 802.11b Only to allow only IEEE 802.11b compliant WLAN devices to 

associate with the Prestige.
Select 802.11g Only to allow only IEEE 802.11g compliant WLAN devices to 

associate with the Prestige.
Select Mixed to allow either IEEE802.11b or IEEE802.11g compliant WLAN devices 

to associate with the Prestige. The transmission rate of your Prestige might be 

reduced.
