Per-IAP Statistics
This is a status only window that provides detailed statistics for the selected IAP.
For a summary of statistics for all IAPs, see “IAP Statistics Summary” on
page 137. Use the Display Percentages checkbox at the upper left to select the
output format — check this option to express each statistic as a percentage of the
total at the top of the column, or leave it blank to display raw numbers.
A quick way to display the statistics for a particular IAP is by clicking the Array
graphic at the bottom left of the WMI window. Click the desired IAP, and the
selected statistics will be displayed. See “User Interface” on page 84.
Receive Error statistics include:
 Total Retries: the count of packets that were sent more than once before
being received correctly.
 CRC error: the count of packets that were corrupted on the air and were
dropped. Some level of CRC errors are expected in wireless networks.
Note that all IAPs operate in a mode where they are listening to
everything all the time, which means they will see many CRC errors.
 Fragment Errors: the count of packets that were incomplete.
 Encryption Errors: the count of packets that had encryption problems.
 Duplicates: the count of packets that were received more than once. The
duplicate packets are dropped.
