DESCRIPTION

Basic Settings

 

 

 

Wireless LAN

Select the check box to turn on the wireless LAN on the NWA1121-NI.

Interface

 

 

 

Operation Mode

Select MBSSID from the drop-down list.

 

 

Wireless Mode

Select 802.11b/g to allow both IEEE802.11b and IEEE802.11g compliant WLAN devices

 

to associate with the NWA1121-NI. The transmission rate of your NWA1121-NI might be

 

reduced.

 

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

 

WLAN devices to associate with the NWA1121-NI. The transmission rate of the NWA1121-

 

NI might be reduced.

 

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

 

NWA1121-NI.

 

 

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 or 802.11b/g/n 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

The SSID (Service Set IDentifier) identifies the Service Set with which a wireless station is

Profile

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 NWA1121-NI from a computer connected to the wireless

 

LAN and you change the NWA1121-NI’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 NWA1121-NI’s new settings.

 

 

#

This is the index number of each SSID profile.

 

 

Activve

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 NWA1121-NI in this field. If there is a high density of APs in

 

an area, decrease the output power of the NWA1121-NI 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 NWA1121-NI’s output power.
