Well, I'm not real sure at times what thing has what IP.  I found this 
on the modem tho:

IP Address / Name 	MAC Address 	Connection Status 	Connection Type
192.168.1.1/ fireball 	1c-6f-65-4c-91-c7 	Offline 	Ethernet
192.168.1.2/ 00259C49FD9D 	00-25-9c-49-fd-9d 	Active 	Ethernet
192.168.1.4/ * 	1c-6f-65-4c-91-c7 	Offline 	Ethernet
192.168.1.6/ * 	00-25-9c-49-fd-9d 	Offline 	Ethernet


The one that says "active" is the router currently connected.  I got it 
to working again.  ;-)  It looks like the modem "remembers" what is 
hooked up and what IPs it was assigned.  Neat huh.   I can't find the 
same thing in the router tho.

I found a how to.  I read it.  This is what I got out of it.  It sounds 
like I need to let the modem use DHCP with the phone company.  Then I 
need to set the ethernet that comes toward the router to say 192.168.1.2 
then set the router to 192.168.1.5 or something to come to my puter..  
Then when I hook up my second puter, I can assign it 192.168.1.6 or 
something.  Best I can figure, no two can have the same IP.  Each device 
has two IPs, one coming in, one going out.  That part sort of confuses 
me a bit.  I need a chalk board for this.

I think the how to may have made this worse.   :-(

I don't know if the reset changed this or not but I did notice that the 
setting "connection type" was set to "on demand" again.  I put it back 
to "always on" which is what I set it to once before.  I was told it 
watches for http traffic and if there is none for a while, it logs off.  
Since I check email, have Kopete running and ntp plus others running, I 
need it on all the time.

Still muddy?  I know it is here.
