Network can’t be reestablished after SLEEP / HIBERNATE – Lenovo G780 Ubuntu 13.10 [solved]
This is a quick fix only:
When waking up from sleep or hibernate the ubuntu network isn’t working properly and no networks can be found.
ctrl – alt – t
and start a terminal window.
type the following:
sudo service network-manager restart
Type your account password and you should see the network system restart and try to connect.
You can’t restart ‘network’ from /etc/init.d – this will crash the system immediately.
