Hi

I have one annoying thing left in my trinity installation, when I
resume, after hibernation or suspend, the network is not only
disconnected but has to be restarted via 
sudo systemctl restart network-manager.service

The culprit is most likely systemd 

However sometimes I have to disable the card in the trinity network card
and enable it again.

Can I mind this operation to  a key?

And in general can I somehow improve whit the sudo solution?

Regards
