LABEL DESCRIPTION

Adapter Setting

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

efficient and allows your AG-220 to operate at the highest possible transmission

(data) rate.

If you want to select a specific transmission rate, select one that the AP or peer

wireless device supports.

Note: With USB 1.0/1.1, the AG-220 can only transmit at up to

11Mbps.

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 AG-220 automatically use short preamble when all access

point or wireless stations support it; otherwise the AG-220 uses long preamble.

Note: The AG-220 and the access point or wireless stations MUST

use the same preamble mode in order to communicate.

Power Saving

Mode

Select Maximum Power Save or Fast Power Save to save power (especially for

notebook computers). This forces the AG-220 to go to sleep mode when it is not

transmitting data.

When you select Continuous Access Mode, the AG-220 will never go to sleep

mode.
