I have a problem with NetworkManger, or to be specific with the nm-applet. When I choose the WiFi network I want to connect to nothing happens. The terminal window I opened nm-applet shows some warnings and errors, but I don't think that they have something to do with the actual problem:

nm-applet (nm-applet:1442): 
nm-applet-WARNING **: Error connecting to ModemManager: Error calling StartServiceByName for org.freedesktop.ModemManager1: 
GDBus.Error:org.freedesktop.systemd1.Load Failed: Unit dbus-org.freedesktop.ModemManager1.service failed to load: No such file or directory. 
** Message: Remote error from secret service: org.freedesktop.DBus.Error.ServiceUnknown: The name org.freedesktop.secrets was not provided by any .service files 

I know that one error occurs because I don't have installed the notification tool that is needed for the GNOME notifications.

NetworkManager's service is running. My wifi on-board card is an Intel Pro/Wireless 5100 AGN (it uses the iwlwifi driver). My distribution is Arch Linux and I'm using the awesome WM.

Yep, modem manager is fine and unrelated to your topic. Try attach something useful from /var/log/messages, you will see more information from NetworkManager – warl0ck Dec 9 '13 at 15:30
