for DFS
This field is available when you select 802.11a in the 802.11 Mode
field.
DFS (dynamic frequency selection) allows an AP to detect other devices
in the same channel. If there is another device using the same channel,
the AP changes to a different channel, so that it can avoid interference
with radar systems or other wireless networks.
Select this option to disable DFS on the NWA when 802.11 Mode is set
to 802.11a.
