interval
This sets the interval to perform background scans. A scan is started each time the interval times out, or if the
idle interval is not timed out when the idle interval is complete. The interval timer is started when the scan is
started, so a idle period timeout will “shift” all subsequent scan intervals. The interval value is specified in
seconds. This command has a corresponding get command, and its default value is 300.

beacon interval
This command will set the AP’s beacon interval value, in milliseconds. This value determines the number of
milliseconds between beacon transmissions. For the multiple VAP case, the beacons are transmitted evenly
within this interval. Thus, if 4 VAPs are created and the beacon interval is 200 milliseconds, a beacon will be
transmitted from the radio portion every 50 milliseconds, from each VAP in a round-robin fashion. The default
value of the interval is 100 milliseconds. This command has a corresponding get command.

blockdfschan 1|0
This command will disable the selection of dfs channels when the 802.11h channel switch processing is
selecting a new channel. Typically, when a radar is detected on a channel, a new channel is picked randomly
from the list. DFS channels are normally included in the list, so if there are several radars in the area another hit
is possible. Setting this selection to 0 disables the use of DFS channels in the selection process, while a value of
1 enables DFS channels. The default value is 1.. This limits the number of available channels. This command
does not have a corresponding get command.

1|0
This command enables (1) or disables (0) Atheros Super A/G bursting support in the driver. Passing a value of 1
to the driver enables SuperG bursting. Passing a value of 0 to the driver disables Super A/G bursting. This is
nor normally used when using 802.11n devices. This command has a corresponding get command, and its
default value is 0.

This command sets manual channel bandwidth. The values indicate which channel bandwidth to use. Note that
this command only applies to legacy rates – HT rates are controlled with the corresponding 11n commands.
