Thank you for that education. I'll go with a switch then.

I managed to see that fine print through my bifocals when setting up. ;)
So I've done that. Not sure I fully understand what is happening but it
working well except as noted below.

If you have the time, would you explain what happens if you do have 2
routers/DHCP servers on the network. Trying to understand a little more
about networking.

You lost me there. Sorry.

I have done that. Got a second AEBS which acts as a remote for a WDS.
However, our house or neighborhood is "possessed" ;) ;) resulting in my
wife's Mac which is attached wirelessly will often lose connection for
15-60 minutes in the afternoons. Can't figure out why. So to increase
dependability and security I would like to return to wired connections
for most work with wireless as an option. And we have to have some
electrical wiring work done in the house so thought I'd try to add the
ethernet wiring at the same time.

I'll go with the switch suggestion. Thanks.

Thanks very much for the help.
