.3142 seems to be solid in my simpler, 'at home' setup; basically only
one strong access point.  [Running with NetworkManager.....]

Testing in a more complex, multi-network, multi-access point 'at work'
setup provides less joy.

Here is the setup:

Here is log info:

Would it be useful to try this without NetworkManager?
