Description Erike Magegere 2013-11-03 08:15:45 UTC

After network failure (specifically a powerfail on router) netowork management icon shows connected status but clicking on Wired connection only shows "connect".  When selected the network is disconnected for a bit and then goes back to connect selection rather than given statistics panel.  It is like it does not know the system reconnected and it still thinks it needs to connect.  I am running on a laptop and thus the batter keeps the system tinning all equipment downstream is on mains and thus fails.

Reproducible: Always

Steps to Reproduce:
1. System up an connected to network
2. Power fail on router 
3. Cannot get to natwork statistics without reboot
Actual Results:  
kill power on router (or our electric company does so)

Expected Results:  
network management should know that the system reconnected.  and thus does not try to reconnect and fails

This is a complete clean reinstall on Kubuntu 13-10.  Preiously on 13-04 where the network management icon knew that the system reconnected.

It might be a problem in NetworkManager itself, because you have the first version of NM 0.9.8 in Kubuntu and I remember there were a lot of issues. I'll try to reproduce your issue so we can be sure where is the problem.

What version of NM do you have? This almost certainly sounds like a NM bug...

Comment 3 Erike Magegere 2013-11-11 13:01:54 UTC

I get from the help 
Connection editor
Version 0.9.3.0
Using KDE Development Platform 4.11.2

and
Using NM version: 0.9.8.0
this was on a fresh install of Kubuntu 13-10

I still have 13-04 as dual boot and this does not occur there.
This also occurs on simply disconnecting the network cable
power fails are a normal occurrence here and it is a major annoyance
rather than a show stopper.

Thank you

Eric

Lukáš, does comment #3 provide the requested information? Please set the bug status.

Comment 5 Jan Grulich 2013-11-20 10:02:36 UTC

I still think the problem is in NetworkManager, because we probably don't get some signal from NM properly and it causes your problem. The reason why it works in Kubuntu 13.04 is that there is previous version of NetworkManager.

Comment 6 Erike Magegere 2013-12-28 13:17:46 UTC

I have upgraded to KDE 4.12 and the operation has changed slightly.
When the system connects again and the connection 1 is selected only connect is available.  If connect is selected the network disconnects and reconnect and then when wired connection is 1 is selected the graph et all is as it should be.  look like a bit of synchronization between the actual network status and the applet somewhere is lost.  So with an additional connect all is well.

Comment 7 Jan Grulich 2014-04-22 13:38:41 UTC

Is this problem still reproducible with the latest version of plasma-nm? Kubuntu 13.10 has quite old version of plasma-nm and NetworkManager, so would be great to test that with Kubuntu 14.04.

Comment 8 Jan Grulich 2014-05-27 11:43:14 UTC

I guess it's fixed either in Kubuntu 14.04 due to newer NetworkManager and plasma-nm or in development version of plasma-nm, where we have rewritten this functionality. Please reopen this bugreport if you are still able to reproduce this issue with Kubuntu 14.04.
