142 The Statistics Menu
This mode is an all-purpose tool for maintaining performance and security on a
WLAN that uses APs, showing you:
• Wireless stations that are connected to an AP
• Non-wired stations that they communicate with
• Levels of signal strength, quality, data transfer rates, and non-data transfer rates
on each station on the access point
• AP traffic totals
For example, you can immediately see if there is a station connected to the wrong AP,
or if an unauthorized AP has been installed. AP statistics will display whether a
station has a problem with quality or range of connection based on the number of
reassociations and retransmissions, or whether a station is misconfigured based on
station poll totals.
There are two Access Point Statistics tabs. The Cumulative tab shows running totals
of statistics collected since the mode was started; the Latest/Min/Max tab shows the
most recent, the minimum, and the maximum values for access point statistics.
The following table describes each statistic shown in List and Graph view.
Note that some columns are turned off by default; right click on the
column heading to set which statistics you want to display.
• Access Point—The MAC address of the Access Point for this row of statistics.
• Station—The MAC address or alias of the station communicating with the AP.
To switch between showing aliases and MAC addresses, press the Setup button
to the left of the display.
The following statistics are available on the Cumulative tab.
• Type—The type of device connected to the AP: a wireless station, a station
(unwired), or another Access Point.
• Avg Strength (%)—The average strength of the signal, expressed as a percentage
of the optimum strength.
• Avg Quality (%)—The average signal-to-noise ratio of the signal, expressed as a
percentage of the optimum.
• Avg Data Rate—The average rate of data packets on the wireless network.
• Avg Rate—The average rate of all packets (data+control+management+beacon)
on the wireless network.
• Packets—The total number of packets seen.
• Data pkts (Directed)—The total number of data packets seen.
