I think I have worked out the cause of the problem,
and managed to cure it.

My WiFi interface on this Fedora-16 machine is wlan0.
For some reason that I do not understand
NM created files ifcfg-dd-wrt and ifcfg-linksys (in addition to ifcfg-wlan0)
in /etc/sysconfig/network-scripts/ 

These (dd-wrt and linksys) are the ESSIDs of two routers
that I use in different places, in fact in different countries,
though I only go occasionally from one to the other.

After moving these files from this directory
the problem seems to have gone away.
NM is still re-writing /etc/resolv.conf ,
but at least it is now giving the correct version.

However, I don't understand why NM wrote these two ifcfg files,
or why they appear to over-rule ifcfg-wlan0.
