Well.....this certainly is embarassing. Yes, I read all I could find 
about Network Manager. But I read nothing about 'nmcli' until this 
morning. I made progress, but the final conclusion was that I could do 
nothing with setting up connections unless Network Manager were running. 
Since I was starting it in a terminal with the "no-daemon" switch, it 
obviously was not running as a daemon, and, apparently not available to 
the configuration tools.

I was spinning my tires and decided to install "network-manager-applet." 
To eliminate the gory details, what I learned was that Network Manager 
was trying to authenticate my wireless card and asking for the password 
to the router. The problem was that it was already associated and I just 
glibly restarted the network when Network Manager brought my NIC down. 
When I start Network Manager on boot, I get that repeating mish-mash and 
must do all this after I've logged on. Is the whole situation as simple 
as removing the "/etc/rc.d/init.d/network" from the boot process? Or is 
it better to just pass "no" from the "ONBOOT" line of ifconfig.wifi0?

What I think I'm experiencing is the collision of sysvinit and systemd. 
I understand now a lot of the remarks in recent posts if this is true. A 
"hybrid" system is difficult to work with.

In this particular case, the philosophy of learning with regard to 
{,B}LFS was quite operational for me. I learned a lot--I think.
