Ibex Network Manager applet removed

John Rose,

I'm also experiencing a similar problem to yours at the moment.

Try running this command in a terminal as a temporary fix:
sudo /etc/init.d/NetworkManager start

If that works, then for some reason the NetworkManager service is not starting. If you're an experienced Linux user you may have old stuff in /etc/network/interfaces file. Reading bug reports, this file seems to cause problems if you have network devices defined in it. I assume you want to be able to manage everything about your network from NetworkManager. So what I did was remove everything from this file. It made no difference to me, but has solved some people's issues.

If you still have issues get back to me, and we'll try and find out some more.

Andrew,

I've removed the static eth0 definition in /etc/network/interfaces and tried sudo /etc/init.d/NetworkManager start. No change. I then tried sudo /etc/init.d/networking interfaces with no return of icon and displayed result of:
  * Reconfiguring network interfaces...
  Ignoring unknown interface eth0=eth0.
Still able to use my eth0 interface though.

That sounds quite strange. Could you double check that both the NetworkManager service and NetworkManager applet are running, by running two commands:

ps aux | grep NetworkManager
ps aux | grep nm-applet

After running Update Manager which installed some kernel stuff, Network
Manager applet now shows in Notification Area. However, it's not sshowing
Wireless Networks as Hardy used to do.

Result of first ps command:

I had the same problems, here is my output from the above commands, note I am currently connected to the network using eth0:

root 6348 0.0 0.4 14752 2516 ? Ssl 14:37 0:00 /usr/sbin/NetworkManager
root 6370 0.0 0.5 6772 2928 ? S 14:37 0:00 /usr/sbin/nm-system-settings --config /etc/NetworkManager/nm-system-settings.conf
root 7942 0.0 0.1 2252 936 ? S 14:51 0:00 /sbin/dhclient -d -sf /usr/lib/NetworkManager/nm-dhcp-client.action -pf /var/run/dhclient-eth0.pid -lf /var/run/dhclient-eth0.lease -cf /var/run/nm-dhclient-eth0.conf eth0
username 8740 0.0 0.1 3240 820 pts/0 S+ 15:01 0:00 grep NetworkManager

and

kirb 8750 0.0 0.1 3236 804 pts/0 S+ 15:01 0:00 grep nm-applet

So I opened another terminal and ran "nm-applet", the applet showed up in the top panel and connected me to my wireless network. Now it is acting like it did under hardy.

here is the new ps output, now I'm connected on my wifi eth1:

root 6348 0.0 0.5 14752 2624 ? Ssl 14:37 0:01 /usr/sbin/NetworkManager
root 6370 0.0 0.5 6772 2928 ? S 14:37 0:00 /usr/sbin/nm-system-settings --config /etc/NetworkManager/nm-system-settings.conf
root 8799 0.0 0.1 2252 948 ? S 15:01 0:00 /sbin/dhclient -d -sf /usr/lib/NetworkManager/nm-dhcp-client.action -pf /var/run/dhclient-eth1.pid -lf /var/run/dhclient-eth1.lease -cf /var/run/nm-dhclient-eth1.conf eth1
kirb 9374 0.0 0.1 3240 816 pts/0 S+ 15:10 0:00 grep NetworkManager

I'm not sure how to correct this permanently though. Potentially add it to on of the startup scripts. But this is a temp work around.

Mosser,

Didn't work. Running nm-applet in another terminal gave:
** (nm-applet:26189): WARNING **: <WARN> applet_dbus_manager_start_service(): Could not acquire the NetworkManagerUserSettings service as it is already taken. Return: 3

(nm-applet:26189): GLib-GObject-CRITICAL **: g_object_unref: assertion `G_IS_OBJECT (object)' failed

this looks like a form posting I saw, here:https://bugs.launchpad.net/ubuntu/+source/network-manager-applet/+bug/249404, and to a lesser extent here: http://ge.ubuntuforums.com/showthread.php?s=a7d56faa33632911f5f8d5e4bfde1329&t=956187 on page 2 and 3.

Another option to try may be to install Network Manager from their PPA, info here:https://launchpad.net/~network-manager/+archive

I don't understand the relevance of those bugs. I'm reluctant to install Network Manager from a source other than the ibex ubuntu repositories. I've got the icon back: I think I did it by /etc/init.d/networking restart after clearing /etc/network/interfaces to only contain commands for lo. However, I'm not able to connect by wireless: Network Manager only shows eth0 (i.e. wired). Under Gutsy & Hardy using ndiswrapper, it showed the Broadcom BCM4306 wireless adapter built into my laptop and available wireless networks. I don't use b43 (or is it bcm43 as my memory fails me) & wl as they didn't work on Hardy.

Network Manager has changed from Hardy to Ibex. Wireless info is now not shown by the Network Manager applet when a wired connection has been made successfully.

Ubuntu 8.10 netwok manager and network manager applet

There are bugs marked "high" for networks-manager and network-manager-applets please see:

https://bugs.launchpad.net/ubuntu/+source/network-manager-applet/+bugs

They are candidate to be solved in short time...

hope this helps
