I logged into my router and checked 192.168.1.222 and 192.168.1.254 and they are both on 255.255.255.0 Subnet Mask.
I have a switch connected because I ran out of ports on my router. I originally had the Cube plugged into the switch but moved it to the router to simply things. Could the switch be 192.168.56.1?
change your router from 192.168.1.254 to 192.168.1.1
raskul beat me to it, but also remember to change the IP address on the Cube to .200.
