The following table describes the labels in this screen.
Preamble Type Preamble is used to signal that data is coming to the receiver. Select the preamble
type that the AP uses.
Short and Long refer to the length of the
synchronization field in a packet.
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 ZyXEL Device automatically use short preamble when all
access point or wireless stations support it; otherwise the ZyXEL Device uses long
preamble.
Note: The ZyXEL Device and the access point MUST use the same
preamble mode in order to communicate.
