Random rare connection instability

[Sprinterfreak]

Sometimes I have some units stubbornly refuse to connect to the WiFi.
In this case I can powercycel them, do what I want, they won't stay connected.

I have multiple access points throughout the property. Today I discovered during a rolling firmware update for my AP's, that the ESP's trying really hard to connect back to an AP where they where connected previously, even if the signal is very weak and the AP is not allowed to accept very low connection rates due to weak signal. The ESP's do not attempt to connect to the AP right next to them, then. This is also known as sticky client phenomena.

Is there anything in the WifiManager which can tweak this poor roaming behavior?
