Adapter Setting

Transfer Rate

In most networking scenarios, the factory default Fully Auto setting is the most 

efficient and allows your M-302 to operate at the highest possible transfer (data) 

rate.
If you want to select a specific transfer rate, select one that the AP or peer wireless 

device supports.

Note: Super G

The Super G technology works with IEEE 802.11 a/b/g 
products. It doubles IEEE 802.11g performance by bonding 
two 54Mbps channels and allowing larger frames to be sent. 

Your M-302 can transmit at up to 108 Mbps when connected 
to an AP or wireless router with the Super G feature enabled.

Preamble Type

Preamble is used to signal that data is coming to the receiver. Select the preamble 

type that the AP uses.
Short Preamble increases performance as less time sending preamble means 

more time for sending data. All IEEE 802.11b/g compliant wireless adapters 

support Long Preamble, but not all support short preamble. 
Select Auto to have the M-302 automatically use short preamble when all access 

point or wireless stations support it; otherwise the M-302 uses long preamble. 

Note: The M-302 and the access point or wireless stations MUST 

use the same preamble mode in order to communicate.

Power Saving 

Mode

Select Maximum Power Saving or Fast Power Saving to save power (especially 

for notebook computers). This forces the M-302 to go to sleep mode when it is not 

transmitting data.
When you select Continuous Access Mode, the M-302 will never go to sleep 

mode.

Save

Click Save to save the changes back to the M-302.
