Statistic Description
Signal Strength The signal strength for all received packets. The higher the value
and the more green the bar graph is, the stronger the signal.
The histogram below the bar graph provides a visual
interpretation of the current signal strength. Differences in signal
strength are indicated by the following colors: green (strongest),
yellow (middle of the range), and red (weakest).
Range: 0 to 100% or –95 to –45 dBm
Signal Quality
(2.4-GHz client adapters)
The signal quality for all received packets. The higher the value
and the more green the bar graph is, the better the quality of the
signal.
The histogram below the bar graph provides a visual
interpretation of the current signal quality. Differences in signal
quality are indicated by the following colors: green (highest
quality), yellow (average), and red (lowest quality).
Range: 0 to 100%
Note This setting appears only for 2.4-GHz client adapters and
only if you selected signal strength to be displayed as a
percentage. See the “Specifying Signal Strength Units”
section on page F-3 for information.
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 (or for
2.4-GHz client adapters using firmware version less than
4.05) and only if you selected signal strength to be
displayed as a percentage. See the “Specifying Signal
Strength Units” section on page F-3 for information.
