I have one question.
Does anyone know what needs to be done to see these two computers?
The router should also have a LAN IP address in the same range, and have the same subnet mask (eg. LAN IP 192.168.1.1, subnet mask 255.255.255.0); you can set that on the router.
Also, both computers need to know that the router's LAN IP address is their router/default gateway. As you don't use DHCP for the two computers, you will have to set that on both computers.
