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

This field displays only when you select 802.11a in the 802.11

switching for DFS

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

Set the operating frequency/channel depending on your particular

ID

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.
