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:
•
•
•
Any one of these results causes both devices to backoff and retry later at
random times. Too many retries can indicate a system problem.
To view retry severity:
1. Select Show Misc Statistics from the Main Menu.
2. Select Retry Histogram to display:
The display indicates the packets that experience retries (up to 15 retries).
3. Press any key to return to the Main Menu.
