DESCRIPTION
Select which WLAN adapter you want to configure.
It is recommended that you configure the first WLAN adapter for AP
functions and use the second WLAN adapter for bridge functions.
Select Access Point from the drop-down list.
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.
Select this to improve data throughput on the WLAN by enabling fast
frame and packet bursting.
This field displays only when you select 802.11a in the 802.11 Mode
field. Select this if you do not want to use DFS (Dynamic Frequency
Selection).
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.
Click this button to have the NWA automatically scan for and select the
channel with the least interference.
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.
