The fragmentation involves more overhead both because of the extra work 
of dividing up and reassembling of frames that it requires, and because it 
increases message traffic on the network. However, the fragmentation can 
help improve network performance and reliability if properly configured.
Sending smaller frames (by using lower fragmentation threshold) might help 
with some interference problems; for example, with microwave ovens.
By default, the fragmentation is off. We recommend not using fragmentation 
unless you suspect the radio interference. The additional headers applied to 
each fragment increase the overhead on the network and can greatly reduce 
the throughput.
RTS Threshold—The Request to Send (RTS) Threshold value. The valid 
integer range must be from 0 to 2347. The default is 2347 octets.
The RTS threshold indicates the number of octets in an MPDU, below which 
an RTS/CTS handshake is not performed.
Changing the RTS threshold can help control the traffic flow through the 
WAP device, especially one with a lot of clients. If you specify a low 
threshold value, the RTS packets are sent more frequently, which consumes 
more bandwidth and reduces the throughput of the packet. However, 
sending more RTS packets can help the network recover from interference 
or collisions that might occur on a busy network, or on a network 
experiencing electromagnetic interference.
Maximum Associated Clients—The maximum number of stations allowed 
to access the WAP device at any one time. You can enter an integer between 
0 and 200. The default is 200 stations.
Transmit Power—A percentage value for the transmit power level for the 
WAP device.
The default value of 100 percent can be more cost-efficient than a lower 
percentage because it gives the WAP device a maximum broadcast range 
and reduces the number of access points needed.
To increase the capacity of the network, place the WAP devices closer 
together and reduce the value of the transmit power. This setting helps 
reduce overlap and interference among the access points. A lower transmit 
power setting can also keep your network more secure because the weaker 
wireless signals are less likely to propagate outside of the physical location 
of your network.
