nm-applet sometimes autostarts, sometimes not

[flrtx]

When I boot my computer, sometimes (but not always) I don't have a network applet in the top right corner. I then have to start nm-applet in a terminal (annoying) and then leave the terminal open the whole time (annoying).
nm-applet is in my autostart list.
What can I do to fix this?
