3.9.2 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 results causes both devices to suspend transmitting and
retries. 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 packets that experience up to 15
retries.
