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.
The bargraph is colored. Red for too weak or too strong signal (>-50dBm), orange when the
signal is within fade margin, and green when signal is above fade margin.
Background noise level is also graphed.
Note that in the above Connectivity screen for an Access Point, the STATUS section for the
Client is "adjustable contention window". If the Access Point is V1.18 or later, you can check
if there are pre-V1.18 units in the system - these units will not have "adjustable contention
window". If this is the case, a compatible contention window size is set, and performance
will not be optimal. Upgrade the firmware on pre-V1.18 units to improve overall
performance.
4.2.2 Monitor Communications
The “Monitor Communications” function buffers the last 30 transmissions since the last enquiry
was made. If there have not been 30 transmissions since the last enquiry, the 805U-E will wait 4
seconds for further transmissions to occur before completing the webpage. Use of this feature
together with the Connectivity webpage will reveal the variability of communications over a
link.
