Get networkmanager and nm-applet working with wireless on Gentoo

Well, more than 1 year working with install_and_use distro (Fedora) makes my brain slow. It takes me about 1/2 day to get it works.

1. Check your USE flag to make sure it has these things:

         bluetooth avahi connection-sharing dhclient autoipd dhcpcd dhclient gnutls nss resolvconf

If you are using the same USE flag with me: ( -* ) , just set it when emerge:

          USE="bluetooth avahi connection-sharing dhclient autoipd dhcpcd dhclient gnutls nss resolvconf" emerge -Nav networkmanager

2.  Install nm-applet(with USE="-doc -debug bluetooth).

3. On this directory, edit all configuration files:

           /etc/dbus-1/system.d

replace every line that contain user="root" with group="plugdev"

4. Add your user and root to group plugdev, add yourself to group netdev
5. Restart dbus, and volla, enjoy wireless networking.

*If you dont add root to group plugdev as step 4, sure you will the error:
