I'm having this problem on Ubuntu 16.04 with 4.4.0-29. It occurs consistently every time after a reboot when I open Chromium (50.0.2661.102-0ubuntu0.16.04.1.1237) and play a YouTube video. It will disconnect once (about 3-4 minutes into a video) an when I re-connect to the same WiFi AP it will stay connected.
