At a high level, I have the same problem:  Network Mnager does not work
anymore after resume, about half the time.

My work around is to run in a terminal:  sudo restart network-manager

As a side effect, nm-applet sometimes crashes when I do that.  But it
works.

At a lower level, I am not sure if my problem is the same as the
original poster; I am not familiar with Network Manager so I have not
yet bothered to dig deep into the logs to figure out what is going one.
I could post the logs if requested.

Title:
  network-manager and wifi not working after resume from suspend

Status in network-manager package in Ubuntu:
  Confirmed

Bug description:
  After resume from suspend, wifi light stays off but wifi connects. 
  After resume from suspend second time, wifi does not connect and network -manager says network not activated, activate network does not help. only reboot does.

  additional info. I added:

  # WORKAROUND: always set the default hibernate mode first (normal mode)
  # (not required if you have the patch mentioned by Rohan below (http://askubuntu.com/a/344879/169))
  HIBERNATE_MODE=platform

  # Always use hibernate instead of suspend, but with "suspend to both"
  if [ "$METHOD" = "suspend" ]; then
    METHOD=hibernate
    HIBERNATE_MODE=suspend
  fi

  # Make sure to use the kernel's method, in case uswsusp is installed etc.
  SLEEP_MODULE=kernel

  to /etc/pm/config.d/00-use-suspend-hybrid
  to be able to suspend to disk.

  Without this file wifi connects after resuspend but as said without
  wifi light on. This was not the case for Ubuntu 13.10
