I tried it with my home office - I just changed the IP address by one
digit and turned off DHCP and it worked fine. As you suggested, with
DHCP turned off, it didn't seem to matter which port I used, nor did it
need a crossover cable.
Thanks to all who responded. Now back to political philosophy...

OK, I agree that I need to turn off DHCP on the "slave" router and give
it a different ID from the "master". But now you are suggesting that I
go from the WAN port on the wired/wireless "slave" to an "in" port on
the router. While that sounds logical, I am wondering if the electronics
on the WAN port can deal hand off to the "in" port the router? Isn't the
WAN port set up to deal with some kind of specialized connections
"handshake" from the ISP's "modem"? (I am asking this out of ignorance.)
It gets confusing because the box offers a bunch of different functions.
You can connect the box in several different ways and you can
enable/disable the various functions.
Every router has 2 sides, usually labeled WAN and LAN, but these names
are only correct if the box is connected in the simplest way. I think it
best to think of WAN as "outside" and LAN as "inside." The LAN side
usually has a bunch of ports and that is where you connect your "inside"
network. The WAN side has just 1 port and you connect that to the
"outside." That "outside" could just be the rest of your bigger LAN. In
that case "inside" is a subnet your have created. A subnet is a LAN that
has a different range of IP addresses than the "outside" LAN. So the
function of the router is to separate networks and control what passes
from one network to the other.
If you turn on the box's WiFi then that gets connected to the "local"
side of the router too.
If you ignore the WAN port, then the box is not being used as a router.
It is just being used as a hub/switch. You will have only 1 network (no
subnets). And the WiFi function is getting added to that 1 network.
So if you have just 1 network you must have just one DHCP server and must
be sude that the box you are adding does not also do DHCP.
If you connect the new box vis its WAN port you have 2 networks (the main
one and the subnet the router box is creating). Then you want both
routers to provide DHCP. One per network.
