thanks, but, this doesn't really seem to accomplish anything other than
clearing up some clutter.  now that i've deleted those connections, the
two that remain are:

ifupdown (eth0), and
ifupdown (br0)

whether i use eth0 or br0 doesn't matter, i can still access my LAN but
no WAN sites...

it seems to me either i can use /etc/network/interfaces or NM.  i think
i would rather just stick with /etc/network/interfaces  so i don't even
understand why NM is running in the first place; it sounds to me like if
/etc/network/interfaces exists then NM shouldn't be running.

i tried 'service network-manager stop' and then NM icon got a red X on
it, but still no internet access (i can still access LAN resources).

also i tried:

$ sudo service networking restart
restart: Unknown instance:
$


$ cat /etc/NetworkManager/nm-system-settings.conf
# This file is installed into /etc/NetworkManager, and is loaded by
# NetworkManager by default.  To override, specify: '--config file'
# during NM startup.  This can be done by appending to DAEMON_OPTS in
# the file:
#
# /etc/default/NetworkManager
#
