Accounting Enable
Select this option to track and measure the resources a particular user has consumed, such as
system time, amount of data transmitted and received, and so on. If you enable RADIUS
accounting, it is enabled for the primary and secondary RADIUS servers.
Interim Interval
The interval between transmitting accounting updates to the RADIUS server. The valid range is
30 to 3600 seconds and the default is 300 seconds.
Advanced wireless settings
The Advanced wireless settings page includes additional parameters concerning the wireless
network.
This page includes the following settings:
Beacon Interval
The Beacon Interval value indicates the frequency interval of the beacon. A beacon is a packet
broadcast by the router to synchronize the wireless network.
DTIM Interval
The DTIM Interval indicates the interval of the Delivery Traffic Indication Message (DTIM). A
DTIM field is a countdown field informing clients of the next window for listening to broadcast
and multicast messages. When the router has buffered broadcast or multicast messages for
associated clients, it sends the next DTIM with a DTIM Interval value. Its clients hear the
beacons and awaken to receive the broadcast and multicast messages. The DTIM value is
decremented every time a beacon is sent at the beacon interval.
RTS Threshold
Sets the packet size threshold at which a Request to Send (RTS) signal must be sent to a
receiving station prior to the sending station starting communications. The router sends RTS
frames to a receiving station to negotiate the sending of a data frame. After receiving an RTS
frame, the station sends a CTS (clear to send) frame to notify the sending station that it can start
sending data.
