6-2.6 Low Throughput
Symptoms
Client computers are experiencing delays when transmitting. One or more of following statistics on
the wireless status page are excessively high: Tx multiple retry frames, Tx single retry frames,
Tx deferred transmissions
Causes
• Too many client stations are using the network, or one or more clients is monopolizing the
bandwidth with excessively large transfers.
• Signal quality to one or more stations is poor or being subject to interference (interference caused
by cordless phone or microwave oven for example). This can cause excessive retransmissions of
data and collisions. Both create overhead that will slow down overall throughput.
• Antenna installation not optimized for adequate coverage area.
• One or more CAP units are sharing the same operating frequency. This can cause excessive
retransmissions to occur, especially if the units are close together.
• The CAP is sharing the same operating frequency with third-party wireless device nearby. This
can cause excessive retransmissions to occur, especially if the units are close together.
