Are you sure the cables were snapped in correctly. Although there is a standard I've found many times some cables just don't work as well with some cards as well as they do with others.
As for setting a static IP within your structure not a static ISP address. Turn off DHCP on your router and assign an IP to your machines in the same schema.
So if your router is 192.168.1.1 with a subnet of 255.255.255.0 then make your machines 192.168.1.2 and 192.168.1.3 with the same subnet.
