Xfce/NetworkManager Applet: Device not Ready

Recently, I bought a new Laptop and installed Arch with the Xfce desktop environment, as usual. Further, I activated NetworkManager and nm-applet.

Often, i.e. not on every boot, after logging in, nm-applet lists my wireless interface with "device not ready". However, if the connection is saved, NM connects nevertheless. nmtui also works flawlessly. As soon as I restart nm-applet, it behaves as it should.

Any ideas?

Thanks for your reply!
While restarting NetworkManager works for the current boot, I don't see the advantage over restarting nm-applet?

I'm still looking for a permanent fix..

Thanks, but I'm sorry to tell you that this doesn't work. Both services were already enabled, they are also working fine - it's nm-applet which thinks that the device is not ready (although it is).

Re: Xfce/NetworkManager Applet: Device not Ready

I just found out that there is indeed an error message reported by nm-applet if it doesn't work. .xsession-errors contains:

(nm-applet:937): GLib-GIO-WARNING **: gdbusobjectmanagerclient.c:1585: Processing InterfaceRemoved signal for path /org/freedesktop/NetworkManager/IP4Config/1 but no object proxy exists

(nm-applet:937): GLib-GIO-WARNING **: gdbusobjectmanagerclient.c:1585: Processing InterfaceRemoved signal for path /org/freedesktop/NetworkManager/IP6Config/1 but no object proxy exists

@zo7aladam: While I appreciate your help, I kindly ask you to only post if you really know a solution or if you need more information. Please stop suggesting installing/removing and/or starting/restarting services if you do not fully understand the problem (as this is my impression).

Regarding your last comment: nm-connection-editor is a dependency of network-manager-applet and thus already installed. My OP also contained the information that I'm running Xfce, so installing it again makes no sense either.

Re: Xfce/NetworkManager Applet: Device not Ready

you are false 
by  reinstall this package archlinux kernel will be able to resume the damaged files in your system

sudo pacman -Rnc gnome-desktop 
sudo pacman -S nm-connection-editor
sudo pacman -S xfce4
mkinitcpio -p linux 
reboot

probably your problem is a conflict of xfce and gnome networkmanager
and see if your problem solved

Re: Xfce/NetworkManager Applet: Device not Ready

And this:

try this

systemctl enable  wpa_supplicant
systemctl enable NetworkManager

this is will fix your problem imediatly

Is most definitely incorrect.  The wpa_supplicant service starts the wpa_supplicant daemon.  So does the NetworkManager service.

They don't play nicely in the same sandbox and will fight with each other.

Re: Xfce/NetworkManager Applet: Device not Ready

I'm now delaying the start of nm-applet for a few seconds, my last five boots were successful (I never had five consecutive reboots without nm-applet reporting 'device not ready').
