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.
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 Scan instead.
Disable DCS to
unlock This appears if the DCS feature is enabled.
Click this to disable DCS and select a channel ID manually.
Note: DCS is Disabled by default
Operating Channel This field displays only when you select 802.11a in the 802.11
Radio Mode field.
This is the channel currently being used by your AP.
RTS/CTS
Threshold Use RTS/CTS to reduce data collisions on the wireless network if you
have wireless clients that are associated with the same AP but out of
range of one another. When enabled, a wireless client sends an RTS
(Request To Send) and then waits for a CTS (Clear To Send) before
it transmits. This stops wireless clients from transmitting packets at
the same time (and causing data collisions).
A wireless client sends an RTS for all packets larger than the number
(of bytes) that you enter here. Set the RTS/CTS equal to or higher
than the fragmentation threshold to turn RTS/CTS off.
Fragmentation
Threshold The threshold (number of bytes) for the fragmentation boundary for
directed messages. It is the maximum data fragment size that can
be sent. Enter an even number between
256 and 2346 .
