Christopher M. Penalver, the output is:

Interestingly, the version coincides with the version information on the
Lenovo site (where I downloaded the update), but the date is one day and
one month earlier than the date on the Lenovo site.

Upon further testing, the problem persists with or without the patch
applied. Please note that in the meantime, I did an apt-get upgrade,
which installed the new 3.16.0-30-generic kernel,.

I'm going to try updating to vivid during the next days.

Title:
  14e4:4365 bcmwl-kernel source: fix for null pointer crash

Status in bcmwl package in Ubuntu:
  Incomplete

Bug description:
  The bcmwl package as of now misses one patch for a bug that occurs
  with BCM43142 and possibly other broadcom chipsets that will look like
  random disconnects, poor wifi signal and kernel warnings, See also
  #1379524.

  Adding the patch is a fairly simple process:

  * put the patch file in /usr/src/bcmwl-6.30.223.248+bdcom/patches
  * add the following line to  /usr/src/bcmwl-6.30.223.248+bdcom/dkms.conf
  PATCH[7]="0014-null-pointer-crash.patch"
  * run: /usr/lib/dkms/common.postinst bcmwl 6.30.223.248+bdcom /usr/share/bcmwl x86_64 $(uname -r)

  This has fixed the issue for me. Edit: I just wanted to add that I did
  not write the patch; I merely downloaded it from a paste that was
  linked from the respective AUR package.
