Comment 10 for bug 1636282

I confirm the same with yakkey on DELL XPS 13 developer edition (2015)

lsb_release -a
No LSB modules are available.
Distributor ID: Ubuntu
Description: Ubuntu 16.10
Release: 16.10
Codename: yakkety

LANG=C apt-cache policy network-manager
network-manager:
  Installed: 1.2.4-0ubuntu1
  Candidate: 1.2.4-0ubuntu1
  Version table:
 *** 1.2.4-0ubuntu1 500
        500 http://fr.archive.ubuntu.com/ubuntu yakkety/main amd64 Packages
        100 /var/lib/dpkg/status

as a temporary work around I put a script here:

/etc/pm/sleep.d/99_restart_network_manager

That contains:

#! /bin/sh

case $1 in
  suspend|suspend_hybrid|hibernate)
  service network-manager restart
  ;;
  resume|thaw)
  # No need to do anything here
  :
  ;;
esac

As said before, it works only once after a suspend.
