Network Connection does not work somestimes after starting system.
After an Newstart it is ok.

In Ubuntu I had the same problem, but there was a opportunity to start the network connection.


Reproducible: Sometimes

Hi, which Kubuntu and Plasma NM versions do you use?

The bug report says you use dsl connection. Is it a system or user connection?

Can you also send me the NetworkManager log so I can take a look at what is happening when NetworkManager starts?
Comment 2 suntone 2014-05-30 15:17:48 UTC
It is the neweset Kubuntu 14.04 installed from DVD.
DSL with Cable.
Network Log...? I don't know.
Comment 3 Lamarque V. Souza 2014-06-24 11:45:45 UTC
Sorry, but I do not use Kubuntu, I do not know which Plasma NM comes in Kubuntu's DVD.

DSL and cable modem are two different technologies to access Internet, do you really use DSL? I really need to know that to figure out what the problem may be. If it is DSL then it will be more difficult to reproduce the problem since I do not have any access to a DSL provider. The NetworkManager's log would really help in this regard. Usually it is stored in /var/log/messages file. Can you compress and send that file to my e-mail (lamarque@kde.org)?
Comment 4 Jan Grulich 2014-06-24 13:07:54 UTC
Kubuntu 14.04 has the new plasma-nm applet. Can you provide NM's log as Lamarque suggested?
Comment 5 suntone 2014-06-24 13:27:18 UTC
 Sorry, but the folder/file "messages" does not exist in /var/log/
Comment 6 Jan Grulich 2014-07-14 08:37:19 UTC
"cat /var/log/syslog | grep NetworkManager" should give you NM's log.

Here it is in the attachment.
Comment 8 Lamarque V. Souza 2014-08-02 17:32:11 UTC
Well, all connection attempts registered in the log were successful. Can you send me the log right after you reproduce this problem? Also send me the output of the commands below so I can take a look at how is your network configuration when the problem happen:

ip addr
ip route
cat /etc/resolv.conf

If you prefer you can send me the output in a private e-mail.

no ethernet connection
Comment 11 apache 2015-06-03 08:42:18 UTC
I think I noticed similar problem several times (Kubuntu 14.04, KDE 4.13.2, kernel 3.13.0-52-generic
) . I use ethernet connection (cable, it usually connects me automatically even after new system install, no settings required, I guess it is called DHCP). 
Sometimes when I log in it just doesn't work. See attached screenshot: "no ethernet connection"

In 12.04 there was an option for it: enable networking
https://dot.kde.org/sites/dot.kde.org/files/network-management-plasmoid.png
Sometimes in 12.04 when I started system and I was disconnected it was enough to uncheck and check the option and I was automatically connected.

Now in 14.04 I can't see this option. Widget only shows active connections and when it list connection there is an option to disconnect. But in case I login to system and there is no active connection enable networking option is not visible. Pressing on a green icon doesn't work. So I need to reboot.

Only after system restart it works again automatically.

Even when I go into connections editor and choose cable connections it doesn't work. Only system restart makes it work again.

If you tell me how, next time I will look for some logs.
Comment 12 apache 2015-06-03 08:49:27 UTC
Ok. Obviously I missed that you already wrote how to find logs. I will do that next time problem appears and sent it to you referring to this bug.
Comment 13 Lamarque V. Souza 2015-06-05 17:46:08 UTC
Apache, you are using an old Plasma NM version that is not maintained anymore. Can you install a newer version and test if the problem still persists? Current Plasma NM version is 0.9.3.5.
Comment 14 Jan Grulich 2015-12-17 13:40:57 UTC
Closing, there won't be any new release of plasma-nm for KDE 4. Switch please to Plasma 5 and re-open this bug if your problem persists.
