Steven, the next step is to fully commit bisect from kernel 3.13 to 4.4
in order to identify the last good kernel commit, followed immediately
by the first bad one. This will allow for a more expedited analysis of
the root cause of your issue. Could you please do this following
https://wiki.ubuntu.com/Kernel/KernelBisection ?

Please note, finding adjacent kernel versions is not fully commit
bisecting.

After the offending commit (not kernel version) has been identified,
then please mark this report Status Confirmed.

Thank you for your understanding.

Title:
  Directly after boot there is no network

Status in linux package in Ubuntu:
  Incomplete

Bug description:
  When doing a cold boot from a full power off, or a soft reboot, after
  gnome loads, I have no Internet connections. This happens without fail
  after every cold boot and intermittently after a soft reboot.

  It has occurred since ubuntu desktop 14.04 all the way up to 16.04. I
  only use kernels that is provided by unbuntu and only when the system
  tells me there is an update to them. I have no custom drivers
  installed, all drivers are from the kernel minus the nivida drivers,
  but it does this even when i dont use the proprietary drivers from
  nvidia.

  The fix for the problem is to soft reboot multiple times until it
  corrects itself. I have done many search's and tried several options,
  none have corrected the problem.

  Im currently using ubuntu desktop 16.04 (gnome)

  below is a copy of dmesg from one of the network failed boots. Let me
  know if there is anything else I can provide to assist.
