Network manager showing no list of wifi networks after resume from suspend

[MichaelE]

Ubuntu 16.10 on Dell XPS 13 9350 (Skylake) with Intel 8260 wifi card. When resuming after supsend, network manager does reconnect to the last wifi but does not show this in the tray icon. Also the menu underneath the icon does not list any wifi networks anymore.

A

  sudo service network-manager restart

solves the issue most of the times, but not always.
