There is a firmware component for IMEI. If I'm not mistaken the IMEI firmware is what is responsible for vpro / AMT functionality. According to this FAQ https://software.intel.com/en-us/articles/intel-vpro-technology-faq, it is capable of controlling a wireless card even while in sleep states. This could be putting the card in an unexpected state while in suspend/sleep.

The update I installed was not simply a windows driver update, but actually a firmware flash presumably for the formentioned vpro/amt functionality.

That being said if your machines are not vpro/amt capable then that's clearly not your issue, but until I hit that issue again it does seem to be what resolved my issue.
