DESCRIPTION
Select this to turn on dynamic channel selection for the APs that the
NXC manages.
Enter a number of minutes. This regulates how often the NXC 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
NXC will then dynamically select the next available clean channel or a
channel with lower interference.
Select the AP's sensitivity level toward other channels. Options are
High, Medium, and Low.
Generally, as long as the area in which your AP is located has minimal
interference from other devices you can set the DCS Sensitivity
Level to Low. This means that the AP has a very broad tolerance.
If you are not sure about the number and location of any other
devices in the region, set the level to Medium. The AP's tolerance for
interference is relatively narrow.
On the other hand, if you know there are numerous other devices in
the region, you should set the level to High to keep the interference
to a minimum. In this case, the NXC's tolerance for interference is
quite strict.
Note: Generally speaking, the higher the sensitivity level, the
more frequently the AP switches channels. As a
consequence, anyone connected to the AP will experience
more frequent disconnects and reconnects unless you
select Enable DCS Client Aware.
