Radio Configuration
Frag. Threshold
This setting determines the size at which packets are fragmented (sent as several
pieces instead of as one block). Enter a setting ranging from 256 to 2338 bytes.
Use a low setting in areas where communication is poor or where there is a great
deal of radio interference.
RTS Threshold
This setting determines the packet size at which the access point issues a request
to send (RTS) before sending the packet. A low RTS Threshold setting can be
useful in areas where many client devices are associating with the access point, or
in areas where the clients are far apart and can detect only the access point and
not each other. Enter a setting ranging from 0 to 2339 bytes.
Max. RTS Retries
The maximum number of times the access point issues an RTS before stopping
the attempt to send the packet through the radio. Enter a value from 1 to 128.
Max. Data Retries
The maximum number of attempts the access point makes to send a packet before
giving up and dropping the packet.
Beacon Period
The amount of time between
beacons in Kilomicroseconds. One K
µ
sec equals
1,024 microseconds.
Data Beacon Rate (DTIM)
This setting, always a multiple of the beacon period, determines how often the
beacon contains a delivery traffic indication message (DTIM). The DTIM tells
power-save client devices that a packet is waiting for them.
If the beacon period is set at 100, its default setting, and the data beacon rate is
set at 1, its default setting, then the access point sends a beacon containing a
DTIM every 100 K
µ
secs. One K
µ
sec equals 1,024 microseconds.
