DTIM Interval
The DTIM Interval sets the Wake-up interval for clients in power-saving mode.
Beacon Interval
A beacon is a packet of information that is sent from a connected device to all other devices
where it announces its availability and readiness. A beacon interval is a period of time (sent with
the beacon) before sending the beacon again. The beacon interval may be adjusted in millisec-
onds (ms).
Preamble Type
Preambles are a sequence of binary bits that help the receivers synchronize and ready for receipt
of a data transmission. Some older wireless systems like 802.11b implementation use shorter
preambles. If you are having difficulty connecting to an older 802.11b device, try using a short
preamble. You can select short preamble on if the 54g mode is set to
802.11b Only in the 54g
Mode field.
