Ohhhh.  Light bulb moment here, I think.  The modem has a network, even 
tho it only has one device connected to it.  The router has its own 
network but can have 4 devices connected to it.  So, if the modem has 
192.168.1.1 >255 then the router needs 192.168.2.1 >255 which is two 
separate networks.

So, if that is true, set the modem to 192.168.1.1 for its IP.  Then set 
the router to to 192.168.2.1 for it's network.  That would give my puter 
a IP and the second puter another IP and they can talk to each other 
since they are on the same network.  Is my light bulb OK so far?

By the way, I feel asleep watching TV, missed my show too.  The internet 
was still up when I got up.  I think that setting on the modem got 
changed during a reset, upgrade on its software or something.  It 
updates software automatically.
