The bar graph 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.
