It didn't have wpa_cli on it.

One suggestion:  Allow setting log-level based on the config file.

But, I managed to hack around to start it with -ddd, and still no useful output
I could find, so maybe it was compiled w/out debugging.

Resolution was to just not open the wifi config window in Android.  Then it does not
constantly scan, and also it does not loose connectivity anymore.  I still don't know
root cause of why it lost connectivity, but could easily be bug in it's wifi driver/firmware,
which appeared to be broadcom.
