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.

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!).
