Maximum associated stations
This the maximum number of wireless clients that can be associated at any one time.
Fragmentation threshold
Fragmentation Threshold is the maximum length of the frame, beyond which payload must be broken up (fragmented)
into two or more frames. Collisions occur more often for long frames because sending them occupies the channel for a
longer period of time, increasing the chance that another station will transmit and cause collision. Reducing
Fragmentation Threshold results in shorter frames that "busy" the channel for shorter periods, reducing packet error
rate and resulting retransmissions. However, shorter frames also increase overhead, degrading maximum possible
throughput, so adjusting this parameter means striking a good balance between error rate and throughput.
RTS threshold
RTS Threshold is the frame size above which an RTS/CTS handshake will be performed before attempting to transmit.
RTS/CTS asks for permission to transmit to reduce collisions, but adds considerable overhead. Disabling RTS/CTS
can reduce overhead and latency in WLANs where all stations are close together, but can increase collisions and
degrade performance in WLANs where stations are far apart and unable to sense each other to avoid collisions (aka
Hidden Nodes). If you are experiencing excessive collisions, you can try turning RTS/CTS on or (if already on) reduce
RTS/CTS Threshold on the affected stations.
Beacon period
In wireless networking, a beacon is a packet sent by a connected device to inform other devices of its presence and
readiness.
When a wirelessly networked device sends a beacon, it includes with it a beacon interval, which specifies the period of
time before it will send 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. Network managers can adjust the beacon interval, usually
measured in milliseconds (ms) or its equivalent, kilo microseconds (Kmsec).
DTIM interval
Delivery Traffic Indication Message. A DTIM is a signal sent as part of a beacon by an access point to a client device in
