I sincerely hope that you are mistaken.

I am left with no choice but to "reveal all and display my dirty linen in
public" (a mixed metaphor?). 

I have yet to learn to read simple messages (and not throw in the towel
when confronted with a string of acronyms that mean nothing to me).
 
But my assertion that the router - in its present environment - will
never connect to the Internet is solidly based.  The router said so
during the configuration; I just did not understand how serious the
message was.

The router's default configuration included "enable NAT" - with
"disable" as an option.  

The default option did not work!

When I opted for the alternative (which worked - after a fashion), I
got the following warning:

NAT allows the LAN PC to have Internet access by sharing the Gateway's
WAN IP.  When NAT is disabled, only standard routing is performed.

I was under the mistaken impression that the "wireless features" of the
router made it suitable for use in conjunction with a laptop. While I do
not own a laptop, I thought the existence of the option does no harm.

I now suspect the the "wireless features" are also invoked during the
configuration to get some vital IP addresses.  

I shall soon know whether I am again clutching at straws.

Meanwhile my thanks to all for the continuing interest and
encouragement.
