If there are two different connections defined in NM with the same
ssid and encryption but each with different BSSID values (i.e. because
there are two APs
in different parts of a building for example), how does NM determine
which of the two to associate with on initial connection?

Is there a way to get NM to always choose the one with the strongest
signal at the time of making the initial connection?

What is the internal NM decision if one then moves from from near the
first AP to the other one so that the signal that was weak initially
then later becomes the stronger signal?

Thanks
