Access point parameters

Beacon interval Sets the time interval between beacons in
milliseconds. This defaults to 100ms – longer
intervals reduce the amount of idle load on the
radio interface, but may increase the time taken
to join a network or roam.
The beacon interval can be changed with the
command
set beacon_interval <
n
>
DTIM interval The number of beacons to count between
DTIMs. The default value is 5 – larger values
will reduce network load, but at the cost of
reduced performance, particularly where clients
are using power saving.
The DTIM interval can be changed using the
command
set dtim_interval <
n
>
TX power Allows the AP power level to be fine-tuned. In
a large installation, using multiple APs, it may
be helpful to reduce the power level to prevent
distant APs from interfering – the default
setting uses the highest power level, which
minimizes the effect of interference and
maximizes range.
The tx power level may be trimmed by entering
the command
set tx_power <
level
