Wireless MAXg USB Adapter: User Guide

 

Fragmentation Threshold

The maximum size in bytes at which packets are fragmented and transmitted a piece at a 

time instead of all at once. Available values range from 256 to 2346. The default value is 

2346.

IBSS 54g Mode

IBSS 54g Mode is used to set the connection type in an ad hoc network. The following 

options are available:

54g - Auto 

54g - Performance

802.11b Only

 (default)

IBSS 54g Protection Mode

A mechanism of prefixing each 

OFDM

 data frame with a request to send/clear to send 

(RTS/CTS) complimentary code keying (

CCK

) frame sequence. The duration fields of the 

RTS and CTS frames should allow the IEEE 802.11b node to correctly set its network 

allocation vector (NAV) and avoid collisions with the subsequent OFDM frames. As 

required for Wi-Fi®, protection mechanisms are enabled automatically whenever an IEEE 

802.11b 

STA

 joins the BSS. If no IEEE 802.11b 

STA

 joins, then no protection mechanism 

is used and full IEEE 802.11g performance is attained. 

Auto

 (default)

Disabled
