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.

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

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 NWA 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 NWA in root AP or repeater mode to set up a wireless connection

between it and another NWA in root AP or repeater mode.

Note: Universal repeater security is independent of the security settings between the NWA and any wireless

clients.

Local MAC

Address

Local MAC Address

is the MAC address of your NWA.

Universal

Repeater SSID

Profile

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

repeater or regular wireless connections with wireless clients.

Note: You can only configure

None

,

WPA-PSK

or

WPA2-PSK

security mode for the SSID

used by a universal repeater connection.

Root MAC

Address

Specify the peer device’s MAC address. The peer device can be a NWA in either 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.
