functions. These settings should only be adjusted by an expert administrator since
incorrect settings can reduce wireless performance. For changes to take effect, you must
click Apply.
Wireless 2.4 GHz/Wireless 5 GHz:
Beacon Interval – Sets the time interval between beacon transmissions in milliseconds.
The Wireless Router uses these transmissions to synchronize the wireless network and its
client devices. For compliance with most client devices, the Beacon Interval should remain
set at the default of 100ms. The allowable setting range is from 20 to 1024ms.
DTIM Interval – Sets the DTIM (Delivery Traffic Indication Message) Interval. The DTIM
Interval informs the wireless client devices of the next available window for listening to
broadcast and multicast messages. When the Wireless Router sends a DTIM beacon, the
client devices hear the beacon and then listen for the messages. For compliance with most
client devices, the DTIM Interval should be left at 1 ms. The allowable setting range is
from 1 to 255 ms.
RTS Threshold – Sets the packet size limit. When the threshold is passed, the ready to
send/clear to send (RTS/CTS) function is invoked. The default setting is 2347 bytes. The
allowable setting range is from 1 to 2347 bytes.
