WiFi problems after waking up from sleep, Ubuntu 16.10

After installing Ubuntu 16.10 I occasionally had problems with WiFi after waking up from sleep.

But of course there’s a workaround (credit to Joakim Koed on askubuntu.com and the solution).

  1. That is not really a solution. It’s a workaround. This problem has been around since Ubuntu implemented systemd and is still not fixed. Thank you for pointing to a working workaround though!
