4.2 Diagnostic Information Available
4.2.1 Connectivity
The Connectivity webpage at an Access Point lists all units for which a transmission was received.
The table shows the averaged receive signal strength and last received radio data rate for each
Client or Access Point by their MAC Address. The unit listed at an Access Point may not even be
in the same system. This can provide an idea of how busy the radio band is.
The connectivity page above shows the stations it is receiving valid status from. These sending
units identity is shown as their corresponding MAC addresses. The graph is a representation of
the RSSI and indicates the value of this RSSI on each channel once they are received. The
background noise and last transmission rate to the unit is also listed in the graph beside each bar
in the graph.
