I did test this and saw that the networks.cfg file was written again.
It appeared that NM was rewriting the config whenever it associated with
an AP.  sjored notes that NM 0.6 behaves this way, but I'm not sure it's
an issue we are trying to address here.  I think the rationale for the
reset button is the following:

    "From the sugar control panel we need to be able to 'reset' or
remove the stored network configuration file. This is important to do
whenever someone makes a change to their AP settings, changes the
password, and it might also help us debug some of the problems we are
seeing with intermittent AP connections. " ( kimquirk, trac #7480 )

The scope of this fix is pretty small.  Just make sure that stored
passwords are reset, and clear out cruft from the networks.cfg file.  Am
I missing anything?  I don't think pushing a fix into NM 0.6 is a good
use of our time, so I'm not sure what else we can do.
