Description
Specify a number between 256 and 2,346 to set the frame size threshold in bytes.
Fragmentation
Threshold
The fragmentation threshold is a way of limiting the size of packets (frames) transmitted over the net-
work. If a packet exceeds the fragmentation threshold set here, the fragmentation function will be acti-
vated and the packet will be sent as multiple 802.11 frames.
If the packet being transmitted is equal to or less than the threshold, fragmentation will not be used.
Setting the threshold to the largest value (2,346 bytes) effectively disables fragmentation.
Fragmentation involves more overhead both because of the extra work of dividing up and reassem-
bling of frames it requires, and because it increases message traffic on the network. However,
fragmentation can help improve network performance and reliability if properly configured.
Sending smaller frames (by using lower fragmentation threshold) may help with some interference
problems; for example, with microwave ovens.
By default, fragmentation is off. We recommend not using fragmentation unless you suspect radio
interference. The additional headers applied to each fragment increase the overhead on the network
and can greatly reduce throughput.
Specify an RTS Threshold value between 0 and 2347.
RTS Threshold
The RTS threshold specifies the packet size of a request to send (RTS) transmission. This helps con-
trol traffic flow through the access point, especially one with a lot of clients.
If you specify a low threshold value, RTS packets will be sent more frequently. This will consume more
bandwidth and reduce the throughput of the packet.
On the other hand, sending more RTS packets can help the network recover from interference or colli-
sions which might occur on a busy network, or on a network experiencing electromagnetic interference.
Specify the maximum number of stations allowed to access this AP at any one time.

Stations
You can enter a value between 0 and 2007.
