I installed M7 on my PC, and everything was working perfectly (even the funny sound issue I get with every openSUSE install on this PC didn’t happen).
But then I put the PC to sleep, and forgetting I’d done this, I turned the power off.
On rebooting, the system hung for a while as networkmanager did its thing. However knetworkmanager wasn’t started and when I started it, it said that network manager was disabled.
I tried rebooting, tried using ifup (where pinging my router worked but pinging google.com didn’t) and I tried disabling ipv6.
/var/log/NetworkManager is empty, as is /var/log/faillog.
/var/log/wpa_supplicant.log gives
and /var/log/localmessages gives
I’m sure the quickest way to solve this would be to reinstall but where’s the fun in that?
Networking is a mystery to me so I have no idea where to start. Any ideas would be welcome!
Hi
Also worth checking the NetworkManger setting
in /etc/sysconfig/network/config and the variable NETWORKMANAGER is set
to yes. You can do this via YaST /etc/sysconfig editor.

I note both eth0’s and wlan0’s states are unmanaged.
I’ve also remembered that (with a KDE install) I updated gtk2 from GNOME:Factory OBS, as per the most annoying bugs workaround. Could this have caused the problem?

Not likely as NM works perfectly for me with M7 and did so even when
Firefox was crashing due to the gtk2 problem.
user2304: I don’t think it’s a firmware issue as a) neither eth0 nor wlan0 work with networkmanager, but with ifup they can both ping my local network, b) that bug refers to an intel chipset whereas mine is ralink and c) wlan0 with network manager worked before I, like a fool, cut the power off.
Whilst I could zypper dup, I’d quite like to use this as a learning experience as I know nothing of networking with openSUSE. That is of course if anyone is anyone is willing to help me!
have you filed a bug-report for this one? I have exactly the same problem - system went to sleep and didn’t come back on (flickering black screen using the NVIDIA drivers) and now the network manager is broken.

In what way is NM broken? I have not seen any problem.
Well, if I do an rcnetwork restart, I get the following output:
Shutting down the NetworkManager done

It does not seem to be able to “connect”. I’ve tried reinstalling all packages, zypper dup, netconfig update, but nothing worked. Only way seems to be reinstalling :(.

thank you so much. I got it working by the following combination (maybe I was too impatient between the first attempt to active and the first status query):
chris@linux-gekz:/usr/share/man> solid-network set networking enabled
chris@linux-gekz:/usr/share/man> solid-network query status
networking: is not enabled
rcnetwork restart (other shell)
chris@linux-gekz:/usr/share/man> solid-network set networking enabled
chris@linux-gekz:/usr/share/man> solid-network query status
networking: is enabled
Hi, I have the same issue when I tried sleeping the system. When I turn it on again the network manager shows as unmanaged.
I followed the commands showed above and I got the same results. However, when I tried #solid-network listdevices
QApplications: qAppName: Please instantiate the QApplication object first.
kdeinit4: preparing to launch /usr/lib64/libkdeinit4_klauncher.so
Klauncher(5921) kdemain: No DBUS session-bus found. Check if you have started the DBUS Server

It would be nice if you guys could add more info to it because even if one knows the workaround fixing this issue is important since nobody should have to mess with the command line just because NM is not active after suspending or some other action.
Thank you for this - I had exactly the same issue with kde4 in the final 11.3 release. “solid-network set networking enabled” alone run as root seems to have fixed it for me!
I had suspended my laptop and it failed to come up again so I was forced to do a hard reboot. KNetworkManager broke after that.
Same thing happened to me (laptop didn’t wake up after hibernating so nm was broken while ifup worked).
solid-network set networking enabled
as root solved it.
and your 11.3 System is not set up for any important work.
