Viewing Statistics for Your Client Adapter
Viewing Statistics for Your Client Adapter
ACU enables you to view statistics that indicate how data is being received and transmitted by your client
adapter.
To view your client adapter’s statistics, open ACU; then click the Statistics icon or select Statistics from
the Commands drop-down menu. The Statistics screen appears (see Figure 7-4).
Note The name of the current profile appears in parentheses at the top of the screen.
Note The receive and transmit statistics are host statistics. That is, they show packets and errors received or
sent by the Windows device. Link status tests from the access point or site survey tool are performed at
the firmware level; therefore, they have no effect on the statistics shown in the Statistics screen.
Current Beacons Received
(5-GHz client adapters)
The percentage of beacon packets received versus those expected to be
received. The higher the value and the more green the bar graph is, the
clearer the signal.
Example: The access point sends out 10 beacons per second, so you
would expect the client adapter to receive 50 beacon packets
in 5 seconds. If it receives only 40 packets, the percentage of
beacons received would be 80%.
Range: 0 to 100%
Note This setting appears only for 5-GHz client adapters.
Overall Link Quality The client adapter’s ability to communicate with the access point,
which is determined by the combined result of the adapter’s signal
strength and signal quality.
Value: Not Associated, Poor, Fair, Good, or Excellent
Note This setting appears for 2.4-GHz client adapters (but only if you
selected signal strength to be displayed as a percentage) and for
5-GHz client adapters. See the Signal Strength Display Units
parameter in Table 7-2 for information.
Signal to Noise Ratio
(2.4-GHz client adapters)
The difference between the signal strength and the current noise level.
The higher the value, the better the client adapter’s ability to
communicate with the access point.
Range: 0 to 90 dB
Note This setting appears only for 2.4-GHz client adapters and only
if you selected signal strength to be displayed in dBm. See the
Signal Strength Display Units parameter in Table 7-2 for
information.
