Operating Mode

Select MBSSID in this field to display the screen as shown

802.11 Mode

Select 802.11b Only to allow only IEEE 802.11b compliant WLAN devices to 

associate with the ZyXEL Device.
Select 802.11g Only to allow only IEEE 802.11g compliant WLAN devices to 

associate with the ZyXEL Device.
Select 802.11b+g to allow both IEEE802.11b and IEEE802.11g compliant 

WLAN devices to associate with the ZyXEL Device. The transmission rate of 

your ZyXEL Device might be reduced.
Select 802.11a (NWA-3160 only) to allow only IEEE 802.11a compliant WLAN 

devices to associate with the ZyXEL Device.

Super Mode

Select this to improve data throughput on the WLAN by enabling fast frame 

and packet bursting.

Choose Channel ID

Set the operating frequency/channel depending on your particular region. To 

manually set the ZyXEL Device to use a channel, select a channel from the 

drop-down list box. 
NWA-3160 and NWA-3163 only: 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 ZyXEL Device automatically select a channel, click 

Scan instead. 

Scan

Click this button to have the ZyXEL Device automatically select the wireless 

channel with the lowest interference.

RTS/CTS Threshold

The threshold (number of bytes) for enabling RTS/CTS handshake. Data with 

a frame size larger than this value will perform the RTS/CTS handshake. 

Setting this attribute to be larger than the maximum MSDU (MAC service data 

unit) size turns off the RTS/CTS handshake. Setting this attribute to its lowest 

value (256) turns on the RTS/CTS handshake. Enter a value between 256 

and 2346.

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.

Output Power

Set the output power of the ZyXEL Device in this field. If there is a high 

density of APs in an area, decrease the output power to reduce interference 

with other APs. Select one of the following 100%(Full Power), 50%, 25%, 

12.5% or Minimum. See the product specifications for more information on 

your ZyXEL Device’s output power.

Select SSID Profile

An SSID profile is the set of parameters relating to one of the ZyXEL Device’s 

BSSs. The SSID (Service Set IDentifier) identifies the Service Set with which 

a wireless station is associated. Wireless stations associating with the access 

point (AP) must have the same SSID. 

Index

Select the check box to activate an SSID profile.
