It get weirder... This morning I fired up on wireless; all seeming to
work ok until I go to print via the printer on my other machine. I
notice that it's timing out, so I try pinging the printer machine by
it's host name and find that it's screwed up as well. The printer
machine is (name is gg2xp) and this machines fixed IP for
the wired nic is (gg-laptop) - here is the result from the

~$ ping gg2xp
PING gg2xp ( 56(84) bytes of data.
>From gg-laptop.local ( icmp_seq=1 Destination Host Unreachable
>From gg-laptop.local ( icmp_seq=2 Destination Host Unreachable

Notice that the ping initially identifies gg2xp as, but
then says that it's pinging from gg-laptop.local (huh?) but can't reach
the host. So I look at my hosts file & all looks correct (gg2xp is
properly entered as & try pinging the IP directly only to
find that I can't even ping by IP.

So I look, and sure enough, the /etc/resolv.conf file is screwed up
again - it has the wireless router in it this time (on,
which allows me to surf the internet & ping google.com for example, but
doesn't get me to my wired lan which is on 192.168.2.xxx. So, now I
guess that I've got to go in and set/reset routes to the wired router.

This is bizarre. I'm thinking of taking Erik's advise & purge NM and
configure everything manually... and I very much agree with his
statement that helper apps shouldn't interfere with manual settings in
traditional config files.
