That said, using that kernel, I've had times when it's locked up -
acting like I have no network connection but not saying disconnected.
turning wifi off and on again (via network manager) brought it back
again. Couuld be coincidence, but never needed to do this before.

Title:
  Wireless networking unavailable/does not work

Status in “linux” package in Ubuntu:
  Confirmed

Bug description:
  After an upgrade to the linux-image-3.2.0-56-generic kernel on Ubuntu
  12.04.3 LTS, my laptop had no wifi. No lights, nothing in network
  manager to even acknowledge the existance of a wireless capability.

  On rebooting into the previous kernel linux-image-3.2.0-55-generic it
  works again (and thus I am able to report this!).
