and finally, 

1. it seems as though I can always reconnect reliably by doing 

      sudo /etc/init.d/dbus restart

2. I have two access points on this network with the same SSID.
   Sometimes it will connect to the one that's further away, so the
   reception is weak.  That happens under Windows, too, FWIW.
