Chapter 22 Dynamic Channel Selection
In this example, if the NWA attempts to broadcast on channels 1, 2, or 3 it is
met with cross-channel interference from the other AP that shares the channel.
This can result in noticeably slower data transfer rates, the dropping of the
connection altogether, or even lost data packets.
However, if the NWA broadcasts on the otherwise empty channel 4 then there will
be minimal interference and a clearer connection to the network.
To alleviate this problem of having to manually change channels every time
interference crops up, you would normally need to scan the area quite often to see
which channels are currently unused then set your device to use one of them. But
with Dynamic Channel Selection, the NWA does this automatically.

DESCRIPTION
Select this to either Enable or Disable dynamic channel
selection.
Enter a number of minutes. This regulates how often the NWA
surveys the other APs within its broadcast radius. If the
channel on which it is currently broadcasting suddenly comes
into use by another AP, the NWA will then dynamically select
the next available empty channel.
Select the NWA's sensitivity level toward other channels.
Options are High, Medium, and Low.
