I'm not sure I would say it worked well, but it did fix one of two
problems.  The second was only fixed after both driver and firmware
upgrades.  I'm no longer running the 19.ucode version.  Would apport
data for the 21 version with the updated driver be useful?

Title:
  Frequent disconnects with Intel 8260 wireless NIC

Status in linux package in Ubuntu:
  Incomplete
Status in linux-firmware package in Ubuntu:
  Triaged

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.
