I can confirm I've the same (very annoying) bug. I don't have the file that Paul L. is talking about, but when I do "sudo service network- manager restart" it works (but it's dirty, even in the /etc/rc.local folder).
I don't know if it can be useful but here are some logs (I aslept and awoke my laptop) : $ cat /var/log/syslog | grep -i network Dec 23 17:13:36 tblinux NetworkManager[1003]: <info> sleep requested (sleeping: no enabled: yes) Dec 23 17:13:36 tblinux NetworkManager[1003]: <info> sleeping or disabling...
