NetworkManager has functionality to enable/disable the wireless, it's
just not exposed from the user interface yet. I believe Simon has been
looking into this. In the mean-time, you can disable wireless by
dbus-send --system \
and NetworkManager won't try to use either of the 802.11bg or the mesh
interfaces until the next reboot.
