	Chapter 6 Wireless LAN
Table 14 Wireless LAN > Wireless Settings: MBSSID (continued)
LABEL	DESCRIPTION
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	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 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.

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 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.
