Wireless Network Management
Monitoring the Wireless Network
The RF Status section displays statistics dealing with the status of the radio
medium. The statistics apply to all radios mapped to the WLAN:
■ Avg Station Signal (dBm)—average signal level detected for all stations
associated to the WLAN
■ Avg Station Noise (dBm)—average background noise for all stations asso-
ciated to the WLAN
■ Avg Station SNR (dBm)—average SNR for all stations associated to the
WLAN
In the Errors section, the Web browser interface reports the total number of
error packets in the entire WLAN:
■ Avg Number of Retries—average number of attempts radios must make to
successfully transmit a packet to stations in this WLAN
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 xl
Module never successfully transmitted to a station associated to this
WLAN
■ % of Undecipherable Pkts—percentage of packets in this WLAN 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 statistics in black apply to the last 30 seconds, giving you a snapshot of
current performance. The statistics in blue show activity in the WLAN over
the last hour.

The Wireless Edge Services xl Module can create a graph of statistics for a
WLAN, which displays how the statistics change over time.
To view this graph, follow these steps:
