Don't use two interfaces with the same IP address. That can't work. Please
note: An IP address defines an interface, not a machine. Probably this is
the reason why your laptop can't talk to anybody.

exactly!
dhenson@Mars-laptop:~$ cat /etc/hosts
127.0.0.1 localhost
192.168.1.51 Earth-svr.site Earth-svr
192.168.1.52 Venus-ws.site Venus-ws
192.168.1.53 Mars-laptop.site Mars-laptop [.site] <--this you can delete for reasons of consitency
192.168.1.54 Mars-laptop-wlan.site Mars-laptop-wlan

(I am assuming that you will assign .54 to your Laptop wlan interface, now.
I am also assuming that you want to get to your laptop via wlan, as
well. If not, skip this last line)
The original install used DHCP but I am tryng to switch to static.


If you do not want to use dhcp at all (imho that would easily make your
mess disappear), then you might use THIS hosts file as a template that
you can copy to any machine on your network.

My Linksys router/switch has a firewall. I use that and my machines
have their firewalls turned off.
I don't see an entry for your router in any of your /etc/hosts files. You
should add a line

192.168.1.1 router.site router
This does not do any harm, but afaik it is not needed, since the default
gateway should be stored within your network interface configuration
(/etc/sysconfig/network/....).
to each of the files (I assume it has the address 192.168.1.1). Otherwise
you can't talk to the internet.

no, what benefit do you get from having a name instead of an ip address
of your router? Well, it is easier to ping, but this does not make your
connection to the internet work, if it did not work before, that is.

BTW: Why don't you want to use DHCP? It can make life so much easier. If
you just don't want to use the built-in DHCP server of the router you
could install a DHCP server e.g. on your Earth-svr machine.

well spoken!!! Imho you should think about it

IIRC, the problem was with setting up DNS. DHCP seems rather
straightforward. Is DNS difficult to set up?
