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:
1
Select
Statistics
from the Main Menu.
2
Select
Retry Histogram
. The display indicates the packets that experience retries
(up to 15 retries).
