Askubuntu came up with the answer:
sudo rfkill unblock wifi; sudo rfkill unblock all
Afterward I was able to enable wifi again via the GUI. But there is
still strangeness. The 'iw wlan0 scan' command found only one network
(a neighbor). It didn't even find my own network. A few moments later I
clicked on the panel icon for nm-applet, and it listed my own network
and half a dozen neighbors. It still didn't show the Flashair, however.
I went back to the command line and repeated the command. Again it
displayed only the one neighbor. But I have a clue: The one neighbor is
open, no security, where all the others are secured, including my own
and (presumably) the Flashair. 'Man iw' says very little, and 'iw
--help' says too much; way more than I can understand.
