Here is what finally solved the problem.  

First, I must confess that I _almost_ cross-posted.  For that I apologise.  I 
posted here, and then someone posted an almost identical problem on another 
list to which I am subscribed, and I joined in.

But misdemeanour ought not to be so richly rewarded....

I gained a huge amount of extremely useful - and educative - knowledge from 
both of you.  I now know something of how the inner workings of ethernet are 
supposed to work, and understand better what configuration and start-up files 
exist and what they look like.

Rather than give the archives a full account of what I actually did, which 
took me in all something like a total of ten hours, here is what I would do 
first another time, which I reckon would take not much more than 10 minutes:

-------------------------------------------------------------------------
purge Network Manager.
create or edit /etc/network/interfaces (I would choose static IP if 
practicable)
create, or check, and edit if necessary, /etc/resolv.conf

restart network, or reboot.  (I tend to prefer the latter, but cannot begin to 
justify my preference.)
--------------------------------------------------------------------------

Reinhold's disabling of Network Manager (see earlier in this thread) had in 
fact worked for me as it does for him, but I didn't realise it.  And purging 
NM was _much_ more fun.  I don't normally enjoy destruction of any kind, but 
I enjoyed that! ;-)
