["Christopher M. Penalver" <christopher.m.penalver@xxxxxxxxx>]

Mahsa Mohammadkhani, just to advise, I asked to you specify which of the
two build instructions you used because you never advised explicitly if
you only used one or both, nor did you give a click for click on both of
these. Quoting previous comments is unhelpful here as I already read all
your comments, and the answer to my question isn't found in them, hence
my question.

Despite this, given this is a downstream issue, and the commit is not
able to be identified so far, this will have to be addressed by the
Ubuntu Kernel Team.

Title:
  10ec:818b [Lenovo ThinkPad T440] WiFi does not reconnect after
  resuming from sleep in Ubuntu 14.10

Status in linux package in Ubuntu:
  Triaged

Bug description:
  After resuming from suspend via closing the lid, my wireless doesn't
  work. It  finds the wireless network and tries to reconnect but fails.
  The only I can solve it now is by restarting. This happens with both
  my home and university AP. I do not have any other problem with these
  APs with my other laptop.

  I tried to re-initialize the kernel module but it doesn't work as per dmesg:
