DESCRIPTION

 

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.

 

 

It is recommended that you select 20/40MHz. This allows the NWA1121-NI to adjust the

 

 

channel bandwidth depending on network conditions.

 

 

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.

 

 

 

Universal Repeater Settings

The Universal repeater function allows the NWA1121-NI in root AP or repeater mode to set up a wireless connection between it and another NWA1121-NI in root AP or repeater mode.

Note: Universal repeater security is independent of the security settings between the NWA1121-NI and any wireless clients.

Local MAC

Local MAC Address is the MAC address of your NWA1121-NI.

Address

 

 

 

Universal

Select the SSID profile you want to use for universal repeater connections with an AP or

Repeater SSID

repeater or regular wireless connections with wireless clients.

Profile

 

 

Note: You can only configure None, WPA-PSKor WPA2-PSKsecurity mode for the SSID

 

used by a universal repeater connection.

 

 

Root MAC

Specify the peer device’s MAC address. The peer device can be a NWA1121-NI in either

Address

root AP mode or repeater mode.

 

 

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.
