NetwokManager Plasma applet - missing speed status connection

Just wondering maybe someone had the same issue with networkmanager KDE-Plasma applet. Lan and Wi-Fi network work fine however when I open from bottom panel Plasma network applet and choose active connection then speed graph in wireless and wire connection show zero status and seems like no traffic however there is traffic fe conky show all traffic without issues! Any idea? Appreciate your help guys...

Re: NetwokManager Plasma applet - missing speed status connection

OK I think that I resolved issue. This what I did it:

systemctl enable netctl
systemctl enable dhcpcd
systemctl enable dhcpcd.service
systemctl enable dhcpcd@enp0s25

systemctl start netctl
systemctl start dhcpcd
systemctl start dhcpcd.service
systemctl start dhcpcd@enp0s25

systemctl restart NetworkManager

Re: NetwokManager Plasma applet - missing speed status connection

That actually works? 
NetworkManager does not work well when other things start dhcpd.  There you have three things controlling it ( enable dhcpcd and enable dhcpcd.service are redundant)

...
systemctl enable dhcpcd
systemctl enable dhcpcd.service
systemctl enable dhcpcd@enp0s25
...

This is really bad form.  See: Here:

dhcpcd.service can be enabled without specifying an interface. This may, however, create a race condition at boot with systemd-udevd trying to apply a predictable network interface name

Always enable dhcpcd@interface and do not do the other two you did.

Re: NetwokManager Plasma applet - missing speed status connection

Thanks for replay to me I just trying to find solution to activate network traffic graph in Plasma network manager applet
I disable dhcpcd@enp0s25 now.
Are you suggest to disable dhcpcd at all?

Regarding to Network Manager speed status issue I discover now that after every reboot is dad however when will do:

systemctl restart NetworkManager

then Network Manager speed status is on and working fine but don't want really restart every KDE new session, any idea why is like that?

Re: NetwokManager Plasma applet - missing speed status connection

You should disable all dhcpcd services except dhcpcd@enp0s25.

As for NetworkManager, I don't use it.  Would probably be fruitful to check out its Wiki page.

Re: NetwokManager Plasma applet - missing speed status connection

Like Ewaller mentioned, it's probably best to actually let NetworkManager manage the network if you want to use the applet.

Stop and disable all dhcpcd services (including dhcpcd@enp0s25). Start and enable NetworkManager.service and use the applet (or any other NetworkManager configuration tool) to set up the network. It will take care of dhcp by itself (using dhclient AFAIK).

I haven't used NetworkManager in ages but I assume that should work. If it doesn't, you can probably get it to work using the wiki.

Re: NetwokManager Plasma applet - missing speed status connection

Thank you guys for your advice. All dhcpcd has been disable now. Yes Steef435 I agree NetworkManager care about dhcp itself. When I used previous KDE4 always disable dhcpcd before start NetworkManager but never had issue with traffic monitor in NetworkManager like now in KDE Plasma.

Re: NetwokManager Plasma applet - missing speed status connection

NetworkManager v1.0.10 works fine in Plasma KDE however from any reason disappearing upload/download status. This can be NetworkManager v1.0.10 bug.
