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:

1Select Statistics from the Main Menu.

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

3Press any key to return to the Main Menu.
