Monitoring the Wireless Network
You can use the RF Status section to monitor the quality of radio media on a network-
wide level, and you can use the Errors section to look for problems with congestion
or interference. You can then examine these statistics for radios or for WLANs to
pinpoint the source of a problem.
The RF Status includes these statistics:
■ Avg Station Signal (dBm)—average signal level detected for all stations associ-
ated to the Wireless Edge Services zl Module
■ Avg Station Noise (dBm)—average background noise for all stations associated
to the module
■ Avg Station SNR (dBm)—average SNR for all stations associated to the module
In the Errors section, the Web browser interface reports the total number of error
packets for this Wireless Edge Services zl Module:
■ Avg Number of Retries—average number of attempts to transmit a packet to a
station
■ % Gave Up Pkts—number of packets that the Wireless Edge Services zl Module
never successfully transmitted to a station
■ % of Undecipherable Pkts—percentage of packets received that could not be
deciphered
A high percentage might indicate that someone is attempting to guess a static
WEP key or WPA/WPA2 PSK.
