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.

Title:
  wireless network has problem connecting and sometimes disconnect

Status in linux package in Ubuntu:
  Fix Released

Bug description:
  Binary package hint: network-manager

  Lenovo T60 with an Intel wireless card.

  Wireless worked flawlessly in 9.04 and 9.10. My other computers still
  running 9.10 don't have any problem on the same wireless routes.

  Just upgraded to 10.4 beta and often runs into these two problems.

  1) after resuming from suspend, it cannot connect. Looking at
  daemon.log I see:

  NetworkManager: <info>  (wlan0): supplicant connection state:  4-way handshake -> associated
  aristotle wpa_supplicant[1055]: WPA: Could not verify EAPOL-Key MIC - dropping packet
  aristotle avahi-daemon[911]: Registering new address record for fe80::21c:bfff:fe08:704a on wlan0.*.
  aristotle wpa_supplicant[1055]: WPA: Could not verify EAPOL-Key MIC - dropping packet
  aristotle wpa_supplicant[1055]: WPA: Could not verify EAPOL-Key MIC - dropping packet


  2) sometimes it just disconnect. This seems to be related to traffic,
  it only happens when streaming video from the net (youtube, vimeo,
  etc...). Doing a tail -f on daemon.log, this appears at the exact time
  that I loose my connection:

  wpa_supplicant[1055]: CTRL-EVENT-DISCONNECTED - Disconnect event -
  remove keys
