Lubuntu nm-applet wifi icon missing [duplicate]

I have a Lubuntu (now 14.04) installation. Recently, I logged in to find that the Wi-Fi icon had disappeared, and there was some sort of a keyboard icon in it's place. I have restarted multiple times, but it doesn't fix it. I can't find the same applet in the panel settings, and resetting the panel didn't help. When I try to manually start nm-applet, it starts, but prints a bunch of warnings to the console:

nm-applet-Message: using fallback from indicator to GtkStatusIcon

It then starts, using ugly icons for the Wi-Fi connectivity symbol.

What do I need to do to make it start correctly? Once it starts, why isn't it using the right icons?

To fix the Network Manager not showing up on the panel issue, from the Lubuntu menu select Preferences > Default applications for LXSession, then click on the Autostart tab and under "Manual autostarted applications" type "nm-applet", then click the "+ Add" button on the left:

Now log out, log back in and you should see the Network Manager icon on the panel: http://www.webupd8.org/2014/04/fix-lubuntu-1404-network-manager.html
