   After a bit more fumbling two new wrinkles emerged. One was a report   
   of wifi being turned off by rfkill. This happened once before, and   
   re-setting the locale options seemed to fix it. This time re-establishing   
   the locale had no detectable effect.   
      
   After a bit more fumbling it appears that the wifi connects readily   
   when the wired ethernet is also connected. Maybe that's significant,   
   but exactly how isn't apparent to me.   
      
   Thanks for posting the hints on using nmcli!
