Title:
  Frequent disconnects with Intel 8260 wireless NIC

Status in linux package in Ubuntu:
  Confirmed

Bug description:
  This issue has been resolved upstream and is described in
  https://bugzilla.kernel.org/show_bug.cgi?id=117391

  The current Ubuntu Xenial Xerus kernel (4.4.0-21.37) is built with a
  version of the iwlwifi driver which supports firmware version up to
  iwlwifi-8000C-19.ucode.  However, the matching linux-firmware package
  ships with the -16.ucode version of the firmware, which contains this
  bug.

  The next stable version of the firmware after -16.ucode is -21.ucode,
  but is not supported by the version of the iwlwifi driver in the 4.4.0
  kernel.  In order to fix this issue, either the minor version of the
  firmware (-19.ucode) needs to be included in the linux-firmware
  package or the iwlwifi driver in the kernel package needs to be
  upgraded with a backport of the iwlwifi driver new enough to support
  the -21.ucode firmware.
