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.

Select 802.11n/g to allow both IEEE802.11n and IEEE802.11g 
compliant WLAN devices to associate with the NWA. The transmission 
rate of your NWA might be reduced.

Select 802.11n/a to allow both IEEE802.11n and IEEE802.11a 
compliant WLAN devices to associate with the NWA. The transmission 
rate of your NWA might be reduced.

The options in this field depend on the 802.11 modes that your device 
supports:

• NWA-3166 supports 802.11b/g, 802.11a, 802.11n/g and 

802.11n/a.

• NWA-3160 supports 802.11b only, 802.11g only, 802.11b/g 

and 802.11a.

• NWA-3163 supports 802.11b only, 802.11g only and 802.11b/

g.

Channel Width 

This field displays only when you select  802.11n/g or 802.11n/a in 
the 802.11 Radio Mode field. 

A standard 20MHz channel offers transfer speeds of up to 150Mbps 
whereas a 40MHz channel uses two standard channels and offers 
speeds of up to 300Mbps. However, not all devices support 40MHz 
channels.

Select the channel bandwidth you want to use for your wireless 
network.

It is recommended that you select 20/40 (20/40 MHz). This allows 
the NWA to adjust the channel bandwidth depending on network 
conditions.

Select 20 MHz if you want to lessen radio interference with other 
wireless devices in your neighborhood.
