3.4  Advanced Setting 

The 

“Advanced Setting”

 allows user to enable/disable power saving mode, setup the 

fragmentation threshold and RTS/CTS threshold of the adapter.

 

 

 

 

Parameter 

Description  

Power Saving Mode  

 

          Enable auto power 

saving 

Check the check box to enable power saving mode. You may 

control the power consumption of the adapter by adjusting the 

save power level from 1 to 4. The higher power save level 

selected, the lower power used. Note that lower power is supplied 

may slow down the transmission rate of the adapter.  

 

 

Fragementation Threshold  

This  value defines the  maximum size of packets, any packet size 

larger than the value will be fragmented. If you have decreased 

this value and experience high packet error rates, you can 

increase it again, but it will likely decrease overall network 

performance. Select a  setting within a range of 256 to 2305  bytes. 

Minor change is recommended. 

 

 

RTS / CTS Threshold  

Minimum packet size require d for  an RTS /CTS  (Request To 

Send/Clear to Send ). For packets smaller than this threshold, an 

RTS /CTS  is not sent and the packet is trans mitted directly to the 

WLAN. Select a setting within a range of 0 to 2305 bytes. Minor 

change is recommended
