NWA1000 Series User’s Guide

Wireless Mode

If you are in the Wireless LAN > Wireless Settings or Wireless LAN > Wireless 
Settings- 2.4G screen, you can select from the following:

•

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. 

•

802.11b/g/n to allow IEEE802.11b, IEEE802.11g and IEEE802.11n compliant WLAN 

devices to associate with the NWA. The transmission rate of the NWA might be 

reduced. 

•

802.11n to allow only IEEE802.11n compliant WLAN devices to associate with the 

NWA. 

If you are in the Wireless LAN > Wireless Settings- 5G screen, you can select from 
the following:

•

802.11a/n to allow IEEE802.11a and IEEE802.11n compliant WLAN devices to 

associate with the NWA. 

•

802.11a to allow only IEEE802.11a compliant WLAN devices to associate with the 

NWA. 

•

802.11n to allow only IEEE802.11n compliant WLAN devices to associate with the 

NWA. 

•

802.11a/n/ac to allow IEEE802.11a, IEEE802.11n and IEEE802.11ac compliant 

WLAN devices to associate with the NWA. The transmission rate of the NWA might be 

reduced. 

Channel

Select the operating frequency/channel depending on your particular region from the 
drop-down list box. 

Channel Width 

This field displays only when you select 802.11n, 802.11a/n, 802.11b/g/n or 
802.11a/n/ac in the Wireless 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.

Select 20MHz if you want to lessen radio interference with other wireless devices in your 
neighborhood or the wireless clients do not support channel bonding.

Select SSID 
Profile

The SSID (Service Set IDentifier) identifies the Service Set with which a wireless station is 
associated. Wireless stations associating to the access point (AP) must have the same 
SSID. You can have up to eight SSIDs active at the same time.

Note: If you are configuring the NWA from a computer connected to the wireless LAN and 

you change the NWA’s SSID or security settings, you will lose your wireless 
connection when you press Apply to confirm. You must then change the wireless 
settings of your computer to match the NWA’s new settings.

#

This is the index number of each SSID profile.

Active

Select the check box to enable an SSID profile. Otherwise, clear the check box.

Profile

Select an SSID Profile from the drop-down list box.

Advanced Settings

Beacon Interval

When a wirelessly network device sends a beacon, it includes with it a beacon interval. 
This specifies the time period before the device sends the beacon again. The interval tells 
receiving devices on the network how long they can wait in lowpower mode before waking 
up to handle the beacon. A high value helps save current consumption of the access point.

DTIM Interval

Delivery Traffic Indication Message (DTIM) is the time period after which broadcast and 
multicast packets are transmitted to mobile clients in the Active Power Management 
mode. A high DTIM value can cause clients to lose connectivity with the network. 

Output Power 

Set the output power of the NWA in this field. If there is a high density of APs in an area, 
decrease the output power of the NWA to reduce interference with other APs. Select one 
of the following Full (Full Power), 50%, 25% or 12.5%. See the product specifications 
for more information on your NWA’s output power.
