In this situation NetworkManager is doing _nothing_  Your interfaces
are controlled by the standard startup scripts.

In order for NetworkManager to take control of your interfaces you
must comment them out (or remove them completely).

My 'interfaces' file is two lines:
--
auto lo
iface lo inet loopback
--

And I switch happily between wired (eth0) and many wireless networks
(eth1) using the network manager applet.

Also, don't confuse the network-manager applet (nm-applet -- you'll
have to run it manually once -- this shows up in the notification area
only) with the "Network Monitor" applet (this behaves as a normal
applet)
