5 Refer to the Errors field to reference retry information as well as data transmissions the target access
point 802.11a/n or 802.11 b/g radio either gave up on could not decrypt.

6 Click the Clear Radio Stats button to reset each of the data collection counters to zero in order to
begin new data collections.

Retry Histogram
Refer to the Retry Histogram screen for an overview of the retries transmitted by an Access Point 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 Access Point radio:
1 Select Status and Statistics > Radio Stats > Radio1(802.11b/g/n) Stats > Retry Histogram from the access
point menu tree.
A Radio Histogram screen is available for each Access Point radio.

Displays the average RF signal strength in dBm for all
MUs associated with the radio. The number in black
represents the average signal for the last 30 seconds and
the number in blue represents the average signal for the
last hour. If the signal is low, consider mapping the MU to
a different WLAN, if a better functional grouping of MUs
can be determined.
Displays the average RF noise for all MUs associated with
the access point radio. The number in black represents
MU noise for the last 30 seconds and the number in blue
represents MU noise for the last hour. If MU noise is
excessive, consider moving the MU closer to the access
point, or in area with less conflicting network traffic.
Displays the average Signal to Noise Ratio (SNR) for all
MUs associated with the access point radio. The Signal to
Noise Ratio is an indication of overall RF performance on
your wireless network.
Displays the average number of retries for all MUs
associated with the access point 802.11a/n or 802.11b/g/n
radio. The number in black represents retries for the last
30 seconds and the number in blue represents retries for
the last hour.
Displays the percentage of packets the AP gave up on for
all MUs associated with the access point 802.11a/n or
802.11b/g/n radio. The number in black represents this
statistic for the last 30 seconds and the number in blue
represents this statistic for the last hour.
Displays the percentage of undecryptable packets for all
MUs associated with the 802.11a/n or 802.11b/g/n radio.
The number in black represents packets for the last 30
seconds and the number in blue represents packets for the
last hour.
