[Bug 1386863] Re: 10ec:818b [Lenovo ThinkPad T440] WiFi does not reconnect after resuming from sleep in Ubuntu 14.10

 

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
