DESCRIPTION
Select Access Point from the drop-down list.
Select 802.11b Only to allow only IEEE 802.11b compliant WLAN
devices to associate with the NWA.
Select 802.11g Only to allow only IEEE 802.11g compliant WLAN
devices to associate with the NWA.
Select 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.
Select this to improve data throughput on the WLAN by enabling fast
frame and packet bursting.
Set the operating frequency/channel depending on your particular
region.
To manually set the NWA to use a channel, select a channel from the
drop-down list box. Click MAINTENANCE and then the Channel
Usage tab to open the Channel Usage screen to make sure the
channel is not already used by another AP or independent peer-to-
peer wireless network.
To have the NWA automatically select a channel, click Auto
Selection instead.
Use RTS/CTS to reduce data collisions on the wireless network if you
have wireless clients that are associated with the same AP but out of
range of one another. When enabled, a wireless client sends an RTS
(Request To Send) and then waits for a CTS (Clear To Send) before it
transmits. This stops wireless clients from transmitting packets at the
same time (and causing data collisions).
A wireless client sends an RTS for all packets larger than the number
(of bytes) that you enter here. Set the RTS/CTS equal to or higher
than the fragmentation threshold to turn RTS/CTS off.
The threshold (number of bytes) for the fragmentation boundary for
directed messages. It is the maximum data fragment size that can be
sent. Enter an even number between 256 and 2346.
When a wirelessly networked 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 low-power mode before waking up
to handle the beacon. This value can be set from 30ms to 1000ms. A
high value helps save current consumption of the access point.
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. This value can be
set from 1 to 100.
