7.4.1.1 Retry Histogram
Refer to the Retry Histrogram screen for an overview of the retries transmitted by an AP-5131 radio
and whether those retries contained any data packets. Use this information in combination with the
error fields within a Radio Stats screen to assess overall radio performance.
To display a Retry Histogram screen for an AP-5131 radio:
1. Select Status and Statistics -> Radio Stats -> Radio1(802.11b/g) Stats -> Retry
Histogram from the AP-5131 menu tree.
A Radio Histogram screen is available for each AP-5131 radio (regardless of single or dual-
radio model).
The table’s first column shows 0 under Retries . The value under the Packets column
directly to the right shows the number of packets transmitted by this AP-5131 radio that
required 0 retries (delivered on the first attempt). As you go down the table you can see the
number of packets requiring 1 retry, 2 retries etc. Use this information to assess whether an
abundance of retries warrants reconfiguring the AP-5131 radio to achieve better
performance.
