RTS/CTS Threshold

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.

 

 

 

 

 

 

Fragmentation

The threshold (number of bytes) for the fragmentation boundary

 

 

Threshold

for directed messages. It is the maximum data fragment size that

 

 

 

can be sent. Enter an even number between 256 and 2346.

 

 

 

 

 

 

Beacon Interval

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.

 

 

 

 

 

 

DTIM

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.

 

 

 

 

 

 

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

 

 

 

100%(Full Power), 50%, 25%, 12.5% or Minimum. See the

 

 

 

product specifications for more information on your NWA’s output

 

 

 

power.

 

 

 

Note: Reducing the output power also reduces the NWA’s

 

 

 

effective broadcast radius.

 

 

 

 

 

 

Rates Configuration

This section controls the data rates permitted for clients.

 

 

 

For each Rate, select an option from the Configuration list. The

 

 

 

options are:

 

 

 

Basic (1~11 Mbps only): Clients can always connect to the

 

 

 

access point at this speed.

 

 

 

Optional: Clients can connect to the access point at this

 

 

 

speed, when permitted to do so by the AP.

 

 

 

Disabled: Clients cannot connect to the access point at this

 

 

 

speed.
