802.11 Mode This makes sure that only compliant WLAN devices can associate
with the NWA.
Select 802.11b Only to allow only IEEE 802.11b compliant
WLAN devices to associate with the NWA.
Select 802.11g Only to allow only IEEE 802.11g compliant
WLAN devices to associate with the NWA.
Select 802.11b/g to allow both IEEE802.11b and IEEE802.11g
compliant WLAN devices to associate with the NWA. The
transmission rate of your NWA might be reduced.
Select 802.11a to allow only IEEE 802.11a compliant WLAN
devices to associate with the NWA.
Super Mode Select this to improve data throughput on the WLAN by enabling

Disable channel
switching for DFS This field displays only when you select 802.11a in the 802.11
Radio Mode field. Select this if you do not want to use DFS
(Dynamic Frequency Selection).
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.
Choose Channel ID Set the operating frequency/channel depending on your
particular region.
To manually set the NWA to use a channel, select a channel from
the drop-down list box. Click
MAINTENANCE and then the
Channel Usage tab to open the Channel Usage screen to make
sure the channel is not already used by another AP or
independent peer-to-peer wireless network.
To have the NWA automatically select a channel, click Auto
Selection instead.
Disable DCS to unlock This appears if the DCS feature is enabled.
Click this to disable DCS and select a channel ID manually.
DCS is Disabled by default
If the NWA is configured in Controller AP mode, it is
recommended that you enable Dynamic Channel Selection
(
DCS ). This allows the NWA to select channels with less
intereference for Managed APs.
