Modified comments a bit.

Added a print statement to identify which wireless interface was being
set up by the configuration daemon at any one time.

Added some code to turn down the wireless interface before trying to
set it up.  This is to fix problems with the older Atheros chipsets that
like to hard reset themselves if you try to frob them too fast.

Upped the delay between iwconfig commands to five (5) seconds between
attempts for the same reason.
