Chapter 7 Performing Diagnostics
Running an RF Link Test
Step 6
If you did not set the link test to run continuously, the test ends after the specified number of packets is
sent, and the Stop button changes back to the Start button. To stop the link test at any time, click Stop,
OK, or Cancel.
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, 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.
