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 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:

  2. Select Retry Histogram. The display indicates the packets that experience retries (up to 15 retries).
