Displays the client's number of dropped packets while transmitting to its
connected access point.
Displays the total number of client transmit retries with its connected access
point.
Displays the degree of errors encountered by the client during data
transmission. The higher the error rate, the less reliable the connection or
data transfer is between the client and its connected access point.
Displays the number of receive actions during data transmission with the
client's connected access point.
Displays the number of probes sent. A probe is a program or other device
inserted at a key juncture in a for network for the purpose of monitoring or
collecting data about network activity.
Displays the power save using the Power Save Poll (PSP) mode. Power Save
Poll is a protocol, which helps to reduce the amount of time a radio needs to
powered. PSP allows the WiFi adapter to notify the access point when the
radio is powered down. The access point holds any network packet to be sent
to this radio.
area displays the following information:
Displays information on the RF quality of the selected wireless client. The RF
quality index is the overall effectiveness of the RF environment as a
percentage of the connect rate in both directions as well as the retry rate and
the error rate. The RF quality index value can be interpreted as:
• 0 – 20 (Very low utilization)
• 20 – 40 (Low utilization)
• 40 – 60 (Moderate utilization)
• 60 and above (High utilization)
Displays the average number of retries per packet. A high number indicates
possible network or hardware problems.
Displays the connected client's signal to noise ratio. A high SNR could
warrant a different access point connection to improve performance.
Displays the power of the radio signals in dBm.
Displays the disturbing influences on the signal.
Displays the number of received bit rates altered due to noise, interference,
and distortion. It's a unitless performance measure.
Displays the average call quality using the Mean Opinion Score (MOS) call
quality scale. The MOS scale rates call quality on a scale of 1-5, with higher
scores being better. If the MOS score is lower than 3.5, it's likely users will
not be satisfied with the voice quality.
