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.
