Ubuntu 12.04 Using Gnome Shell NM Applet Issues
I think it may be a bug:

This is the scenario:

I installed a barebones Ubuntu 12.04 using GNOME-SHELL on a usbstick(work related project). All worked fine from the laptop that I did the installation from. It grabbed an ip address automatically assigning the nic (eth0) and the wireless interface (wlan0) correctly. The nm-applet worked fine when you clicked the upper right hand corner in which you could edit the profile(eth0) and or (wlan0) respectively.

So in testing I decided to test this usbstick on several other laptops and desktop to see how things went(Thinkpads,EliteBooks and etc). All worked fine except that Ubuntu is randomly reassigning the interfaces eth1,eth2,wlan1,wlan2 and not consitently keeping them eth0, eth1 like our previous build using Ubuntu 10.04. I can see what is happeneing. When I look at the /etc/NetworkManager/NetworkManager.conf:

Code:
[main]
plugins=ifupdown,keyfile
dns=dnsmasq

[ifupdown]
managed=false

Network Manager is not managing what is in /etc/network/interefaces:

Code:
# The loopback network interface
auto lo
iface lo inet loopback

# The primary network interface
auto eth0
iface eth0 inet dhcp

because the nic interfaces are changing random to something else eth1,eth2,wlan1,wlan2 on the other machines that I am using for testing thus disabling the nm-applet icon from appearing in right hand corner on the panel. Ubuntu is randomly assigning them which can be seen under /etc/udev/rules.d/70-persistent-net.rules:

Code:

In addition to that randomly reassignment of the nic interfacing, ip address are not being assigned to the nics because they do not reside in /etc/network/interaces as seen in the above.
