Client Adapter Status (continued)
Description
The signal quality for all received packets. The higher the value and the
more green the bar graph is, the clearer the signal.
Range: 0 to 100%
Note
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.
Range: –100 to –45 dBm
Note
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
Range: 0 to 100%
Note
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:
Note
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

Viewing the Current Status of Your Client Adapter
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 Signal Strength Display Units parameter in
for information.

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%.
This setting appears only for 5-GHz client adapters.
Not Associated, Poor, Fair, Good, Excellent
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.
This setting appears only for 2.4-GHz client adapters and only
if you selected signal strength to be displayed in dBm. See the
