I kind think it was something to do with DHCP or possibly the
fact that the ISP router/modem may not have had DHCP server
capabilities, but to be clear I always rebooted "everything including
all nodes" when making any hardware or software changes.

I must have not worded my post correctly, but the Linksys router
gets a cable from the switch to the Linksys router port one. Then
additionally the Linksys holds some of the nodes itself on it's ports.
Then the Linksys goes out thru it's own "Uplink port" to the ISP
router/modem port LAN-1.
I did try to cable the Linksys router out from it's WAN port to the
ISP router/modem but none of the nodes could get internet access
that way. Not sure why.

I tried with ipconfig and other avenues till I was blue in the
face but I could never get a gateway address for the ISP
router/modem. I could get one on the nodes that went
into the linksys router.
I also could not find info on how to configure "anything"
on the ISP router/modem which is a Zyxel, Prestige 900 series,
the Linksys is model BEFSR81 CABLE/DSL ROUTER,
the switch is a Netgear 16 port hub, model fs116.

Well that's what I had thought during the process, in fact I will cut and
paste my previous post to this,...
-------------
We thought maybe two routers were having trouble existing
together since there was no way to config the default address
of the ISP router/modem. So we bought a switch with enough
ports to handle all the nodes and we ran one cable back from
the switch to the ISP router/modem. We then could only see
3 other random nodes from whichever node we were looking
from and none of the nodes could see out past the ISP router
to the internet, something that I still do not understand.
----------------Maybe I did not make it clear that the Linksys
was out of the equation here, but to be clear it was.
I had all the nodes set to DHCP
