Monitoring the Wireless Network
The Information section describes this radio and shows the number of stations
currently associated to it. You should check the Current Channel listing; if the radio
is configured with a manual channel but currently uses a different channel, the
channel number is listed in red.
On the Details screen, statistics for wireless traffic are broken down into received
and transmitted traffic.
You can view the average status of the wireless medium or all stations connected to
this radio under RF Status:
■ Avg Station Signal (dBm)—average signal level detected for all stations associ-
ated to the radio
■ Avg Station Noise (dBm)—average background noise in the wireless cell
■ Avg Station SNR (dBm)—average SNR for all stations associated to the radio
View the Errors section to monitor for congestion. Statistics include:
■ Avg Number of Retries—average number of retries the radio must make to
successfully transmit a packet
A high value (over 10 or 20 percent) may indicate excessive congestion or
interference from another wireless device.
■ % Gave Up Pkts—number of packets that the Wireless Edge Services zl Module
never successfully transmitted to a station associated to this radio
■ % of Undecipherable Pkts—percentage of packets received by this radio that
could not be deciphered
A high percentage might indicate that someone is attempting to guess a static
WEP key or WPA/WPA2 PSK.
The Details screen also allows you to simultaneously compare statistics for the last 30
seconds and the last hour.
