Follow-up: I disabled 802.11ac on the 5 Ghz band on the router and the laptop stabilized. Go ahead, you explain it.
A friend tells me that one of the "features" shipped in this month's Monthly Update was a re-ordering of the priorities for accessing protocols on the Wifi, and that might cause problems if your WiFi adapter or router offers some protocols but they're not well-implemented/broken.
Perhaps this clue might help someone.

One of our office workstations has been very unhappy since the shutdown Tuesday asked to install updates.
Dell Precision M6800 Workstation i7 2.80GHz, 16 Gb RAM, dual 1Gb HDDs Windows 10 Pro Version 1607 (14393.1593)
Got the usual "Updating..." when restarting this morning. And waited, and waited.
Restarting was sluggish, WiFi kept starting and stopping, After patiently waiting a few minutes, shut down cold and restarted. Worked okay for a while.
Later, "Restart Now or Restart Later?" revealed that some of the recent updates STILL were not successfully installed. Restarted.
Lather, rinse and repeat the above three times.
Attempting to persuade the ever-patient associate not to throw her machine out the window. "That's why they call it Windows," right?
Nothing obvious in the error logs. No disk errors.
Next step will likely be to attempt to restore from the previous rescue point which, in my limited experience of a dozen or so attempts, never works.
Ideas? Suggestions? Mocking?
