Description

Mode	The Mode defines the Physical Layer (PHY) standard being used by the radio.
	Select one of these modes:
	• IEEE 802.11b
	• IEEE 802.11g (the default). This mode allows both 802.11b and 802.11g cli-
	ents to connect to the access point. To enable 802.11g clients only and
	deny acces to 802.11b clients, select a Basic rate that is not supported by
	802.11b, such as 6Mbps. Basic rate options appear at the bottom of the
	Radio tab.
Super G	Enabling Super G provides better performance by increasing radio throughput
	for a radio mode. Keep in mind that with Super G enabled the access point
	transmissions will consume more bandwidth.
	• To enable Super G click Enabled.
	• To disable Super G click Disabled.
Channel	The Channel defines the portion of the radio spectrum that the radio uses for
	transmitting and receiving. The range of channels and the default channel are
	determined by the Mode of the radio interface.
	For most Modes, the default is Auto. Auto is the recommended mode because
	it automatically detects the best channel choices based on signal strength, traf-
	fic loads, and so on.
Beacon Interval	The Beacon Interval value is set in milliseconds. Enter a value within the range
	20–2000.
	Beacon frames are transmitted by an access point at regular intervals to
	announce the existence of the wireless network. The default behaviour is to
	send a beacon frame once every 100 milliseconds (or 10 per second).
DTIM Period	Specify a DTIM period within the range 1–255.
	The Delivery Traffic Information Map (DTIM) message is an element included
	in some Beacon frames. It indicates which clients, currently sleeping in low-
	power mode, have data buffered on the access point awaiting pickup.
	The DTIM period you specify here indicates how often the clients served by
	this access point will check for buffered data still on the access point awaiting
	pickup.
	The measurement is the count of beacons. For example, if you set the DTIM
	period to 1, clients will check for buffered data on the access point at every
	beacon. If you set this to 10, clients will check at every 10th beacon.
