Analyzing Retries
The AP keeps statistics of packets with multiple retries. Use these statistics to 
identify severe occurrences of retries. Retries occur when the transmitting station 
fails to receive an acknowledgment for a transmitted packet. This lack of 
acknowledgment can result from:
Two or more stations transmitting simultaneously and causing collisions
The receiving station moving out of range
The receiving station being powered off.
Any one of these incidents causes both devices to suspend transmitting and retry 
later. Too many retries can indicate a system problem.
To view retry severity, do the following:
Select Statistics from the Main Menu.
Select Retry Histogram. The display indicates the packets that experience retries 
(up to 15 retries).
Press any key to return to the Main Menu.
