Sometimes when I wake up my Ubuntu laptop from suspend mode, it is the case that the Network Manager is having 100% load. I can’t connect to any network, so nothing is working. If you restarted your computer at this point and also get in the checking hdd routine, then your are in bad mood, well at least I was.
A solution I am using is, simply kill the process and restart it again. How to do this?
Just run the two following commands.
sudo killall -9 NetworkManager
sudo /etc/dbus-1/event.d/25NetworkManager start
After a short time the Network Manager starts searching for the Network connection and you are ready to roll.
