Sometimes I miss the Network Connection icon on my top-right panel.This is annoying if you get in this trouble too.Here is an easy way I just found to fix this problem.

Open up a terminal window (Applications->Accessories->Terminal) to run commands.

First,navigate to /etc/NetworkManager/ directory by this command:

cd /etc/NetworkManager/

Then,edit nm-system-settings.conf file:

sudo gedit nm-system-settings.conf

change “managed=false” into “managed=true” and save the file.

Finally,restart the network:

/etc/init.d/networking restart

Done.

Here’s something I noticed about my setup…

I have a default guest account into which the laptop automatically signs in on startup… If the guest user is signed in, I don’t get a network icon. Once I sign the other guy out, mine turns up.

I followed the instructions
But this is what I am getting after I enter the command to restart:

* Reconfiguring network interfaces… ifdown: failed to open statefile /var/run/network/ifstate: Permission denied
WARNING: ifup -a is disabled in favour of NetworkManager.
Set ifupdown:managed=false in /etc/NetworkManager/nm-system-settings.conf.

What is wrong ?
