DTIM Interval Delivery Traffic Indication Message (DTIM), also known as
Beacon Rate. The entry range is a value between 1 and
65535. A DTIM is a countdown informing clients of the next
window for listening to broadcast and multicast messages.
When the AP has buffered broadcast or multicast messages for
associated clients, it sends the next DTIM with a DTIM Interval
value. AP Clients hear the beacons and awaken to receive the
broadcast and multicast messages. The default is 1.
Beacon Interval The amount of time between beacon transmissions. Each
beacon transmission identifies the presence of an access point.
By default, radio NICs passively scan all RF channels and listen
for beacons coming from access points to find a suitable access
point.
Before a station enters power save mode, the station needs
the beacon interval to know when to wake up to receive the
beacon (and learn whether there are buffered frames at the
access point).
The entered value is represented in ms. Default is 100.
Acceptable entry range is 1 to 0xffff (65535)
Xpress
TM
Technology
Xpress Technology is compliant with draft specifications of two
planned wireless industry standards.
54g
TM
Mode Set the mode to 54g Auto for
the widest compatibility. Select the mode to
54g Performance for the fastest performance
among 54g certified equipment. Set
the mode to 54g LRS if you are experiencing
difficulty with legacy 802.11b equipment.
54g Protection In Auto mode the router will use
RTS/CTS to improve 802.11g performance in
mixed 802.11g/802.11b networks. Turn
protection off to maximize 802.11g throughput
under most conditions.
Preamble Type Short preamble is intended for application where maximum
throughput is desired but it doesn’t cooperate with the legacy.
Long preamble interoperates with the current 1 and 2 Mbit/s
DSSS specification as described in IEEE Std 802.11-1999
Transmit Power The router will set different power output (by percentage)
according to this selection.
