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
I
The receiving station moving out of range
I
The receiving station being powered off.
I
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:
1 Select Statistics from the Main Menu.
2 Select Retry Histogram. The display indicates the packets that experience retries
(up to 15 retries).
3 Press any key to return to the Main Menu.
