you set this to 2, clients check on every other beacon. If you set this to
10, clients check on every 10th beacon.
Fragmentation Threshold
Specify a number between 256 and 2,346 to set the frame size
threshold in bytes.
The fragmentation threshold is a way of limiting the size of packets
(frames) transmitted over the network. If a packet exceeds the
fragmentation threshold set here, the fragmentation function is
activated and the packet is sent as multiple 802.11 frames.
If the packet being transmitted is equal to or less than the threshold,
fragmentation is not 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 reassembling 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. Allied Telesyn recommends 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.
RTS Threshold
Specify an RTS threshold value between 0 and 2347.
The RTS threshold specifies the packet size of a request to send
(RTS) transmission. This helps control 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 collisions which might occur on a busy
network, or on a network experiencing electromagnetic interference.
Maximum Stations
Specify the maximum number of stations allowed to access this
access point at any one time.
You can enter a value between 0 and 2007.
