Signal Quality
The signal quality for all received packets. The higher the value
and the more green the bar graph is, the clearer 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 if you selected signal strength to
be displayed as a percentage. See the
Strength Display Units” section on page F-3
for
information.
Noise Level
The level of background radio frequency energy in the 2.4-GHz
band. The lower the value and the more green the bar graph is, the
less background noise present.
The histogram below the bar graph provides a visual
interpretation of the current level of background noise.
Differences in background noise level are indicated by the
following colors: green (low noise), yellow (middle of the range),
and red (high noise).
Range:
–100 to –45 dBm
Note
This setting appears only if you selected signal strength to
be displayed in dBm. See the
Display Units” section on page F-3
for information.
Link Speed
The rate at which your client adapter is transmitting packets to or
from its associated access point.
Value:
1, 2, 5.5, or 11 Mbps
Quality
The client adapter’s ability to communicate with the access point.
Value:
Not Associated, Poor, Fair, Good, Excellent
Note
This setting appears only if you selected signal strength to
be displayed as a percentage. See the
Strength Display Units” section on page F-3
for
information.
Signal to Noise (S-N) Ratio
The difference between the signal strength and the 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 if you selected signal strength to
be displayed in dBm. See the
Display Units” section on page F-3
for information.
