nm-indicator shows no network devices

[Ralf Hildebrandt]

All over a sudden, the nework Manager indicator doesn't show any network connections at all.
At the same time the network DOES work.

Here at work I'm using a simple wired connection with DHCP.

$ lspci |grep -i net

I'm also seeing this issue with wired connection. But in my case I don't have any network connection when it happens. Today there was an update with some network components, and I haven't seen this issue since then, but it does not happen too often, so I will keep watching.

[Mathieu Trudel-Lapierre (cyphermox)]

If you kill nm-applet and restart it, can you then see the devices? I can't reproduce this bug yet, so let's try to find a particular case which would trigger it to show.

Also, please see if you can add debugging logs for NetworkManager; see http://live.gnome.org/NetworkManager/Debugging

[Walter Garcia-Fontes (walter-garcia)]

In my case restarting the network-manager service reestablished networking, but as I said I haven't seen again this issue since yesterdays's updates.

[Ralf Hildebrandt (ralf-hildebrandt)]

After a restart, all is working again.

[Yann Dìnendal (yannbreliere)]

I can also confirm it is now fixed, after a reboot.
