Cannot create new connection while existing connections still working

Kotrfa · 2017-01-04 18:46:06

Hi,

I am facing really weird connection issue on my laptop and one specific router I have at home.

When I turn on wifi connection, I can normally access the internet and internal network as expected. But after a while, the connection stops working and I cannot access any site, ping any server (nor 8.8.8.8) including the router (192.168.0.1) or login to a SSH server. But what is more disturbing is the fact that already created connections, e.g. through x2go are still working fine! Furthermore, the system doesn't signal anything wrong - I have an IP assigned, systemd units don't show anything weird. I have to manually restart netctl to get the connection up again.

Below are some logs:
