Solved! Found my problem with adding: sudo nano ~/.profile; rfkill block wlan and bluetooth was that I didn’t know the ins and outs of the resulting terminal page…didn’t press ^X after entering command, so didn’t Save (Y) change. Once I did, everything worked.
Just a reminder to those who want to help: if a user indicates they are not an experienced linux user, DO NOT assume ANY knowledge. If you suggest a solution, like above, try to include every step (like adding sudo in above and how to save change: ^X, Y.) For an experienced user like yourself this maybe difficult as you are so used to the “obvious” which are not obvious to the inexperienced.
