Mahsa Mohammadkhani, just to clarify, this bug report is only scoped to
WiFi not working after resume from suspend.

With this in mind, is there a reason you would be modprobe'ing if the
WiFi works after resuming from suspend?

Despite this, the next step is to fully reverse commit bisect from
kernel 3.16 to 3.18-rc3 in order to identify the last bad commit,
followed immediately by the first good one. Once this commit has been
identified, then it may be reviewed as a candidate for backporting into
your release. Could you please do this following
https://wiki.ubuntu.com/Kernel/KernelBisection#How_do_I_reverse_bisect_the_upstream_kernel.3F
?  Please note, finding adjacent kernel versions is not fully commit
bisecting.

Thank you for your understanding.

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

Status in “linux” package in Ubuntu:
  Incomplete

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:
  modprobe -r r8192ee && modprobe r8192ee
