WPA_CLI: Difficulty switching from 1connection to another

As requested here is a log of a case of it not connecting to a network after
a connection is established.  In fact this is trying to connect to the very
same network that it was connected to just before.  Sorry couldn't get all
the console msgs but you can see that the connection is authenticated.

Please note: I've added the time to the console msgs, and yes I see that
sometimes it get written twice, not sure why at this moment, but that is not
my concern just now.


Steps:

   1.  wpa_supplicant loads a config file with not ap_scan var and valid
   network variable settings for a network called FeatherSecure.

   2.  through wpa_cli I send a ap_scan=2 command. (because it is
   hidden).

   3. through wpa_cli I send a scan command.

   4.  through wpa_cli I send select_network "FeatherSecure" command.

     I wait for the connection to be established

   5. Then through wpa_cli I send a disconnect command.

   6. through wpa_cli I send another ap_scan=2 command.

   7. through wpa_cli I send another scan command.

   8. through wpa_cli I send another select_network "FeatherSecure"
   command

   9. At this point it just sits there.



console msgs:

Hope this helps you determine what I'm not doing or what is missing.
