   _Which_ "the security settings"?

   A vague description of what does _not_ happen is less useful than a
clear description of what _does_ happen.

   "unable" is not a useful problem description.  It does not say what
you did.  It does not say what happened when you did it.  As usual,
showing actual actions (commands) with their actual results (error
messages, LED indicators, ...) can be more helpful than vague
descriptions or interpretations.

   You're ahead of me.  I can't figure out what you've done so far.
