LABEL DESCRIPTION
WLAN Interface 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.
In addition, it is recommended that you set the WLAN interfaces into
different 802.11 modes. For example, set
WLAN1 to 802.11b/g
(2.4 GHz) and set WLAN2 to 802.11a (5 GHz).
Operating Mode Select Access Point from the drop-down list.
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.
If you are configuring both WLAN interfaces, it is recommended that
you set the WLAN interfaces into different 802.11 modes. For
example, set
WLAN1 to 802.11b/g (2.4 GHz) and set WLAN2 to
802.11a (5 GHz).
Super Mode Select this to improve data throughput on the WLAN by enabling fast
frame and packet bursting.
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.
