No connection to internet after suspending

HI
I’ve updated my tumbleweed to the 20170908 version and now every time when I resume my laptop after suspending it. I got no connection to the my wireless network.
I get the list of wireless networks available, thus the wireless card is working. But when I hit “connect” nothing happens. So I have to reboot my laptop to get connected.

Before the update there was no problem.

ifconfig

HI

Are you using NetworkManager to manage your network connection? Rebooting is a bit extreme! What happens if you simply restart the network?

sudo systemctl restart network

If using NetworkManager, you can also do

sudo systemctl restart NetworkManager

Yes, I’m using NetworkManager.

Thank you, with

sudo systemctl restart NetworkManager

indeed I restart my network and it works properly without rebooting the OS.

I’m getting however the following crash of kdeint5 immediately after restarting the NetworkManager:


kdeninit5 PID:2138 Signal: Segmentation fault (11)

Good - as expected.

This might need a bug report to resolve.
