LABEL DESCRIPTION
Adapter Setting
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 NWD-170N automatically use short preamble when the
access point supports it; otherwise the NWD-170N uses long preamble.
Note: The NWD-170N and the access point MUST use the same
preamble mode in order to communicate.
