network-manager does not reconnect after resuming from suspend

[Craig Magina]

On a 2013 Mac Book Pro 11,1, the network-manager does not reconnect after resuming from suspend. To work around this you need to stop network-manager, delete /var/lib/NetworkManager/NetworkManager.state and then start network-manager again. A more permanent workaround is to put that in a script under /etc/pm/sleep.d/<script>.

i.e. /etc/pm/sleep.d/99_restart-network-manager

#!/bin/sh
case "$1" in
    resume|thaw)
        stop network-manager
        rm /var/lib/NetworkManager/NetworkManager.state
        start network-manager
    ;;
esac
 This occurs under trusty as well.

This only seems to affect the Ubuntu frontend as the KDE version does not suffer this issue.
