Description
Specify whether you want the radio on or off by clicking On or Off.
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 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, traffic loads, and so on.
Beacon frames are transmitted by an access point at regular
intervals to announce the existence of the wireless network. The
default behavior is to send a beacon frame once every 100
milliseconds (or 10 per second).
The Beacon Interval value is set in milliseconds. Enter a value
from 20 to 2000.
The Delivery Traffic Information Map (DTIM) message is an
element included in some
client stations, 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 should check for buffered data still
on the AP awaiting pickup.
Specify a DTIM period within the given range (1 - 255).
The measurement is in beacons. For example, if you set this to
"1" clients will check for buffered data on the AP at every beacon.
If you set this to "2", clients will check on every other beacon. If
you set this to 10, clients will check on every 10th beacon.
