You will need to attach your computer directly to the 655 and have no connections running from the cable box to the 655. You then should be able to get to the 655 and change the IP address on it. YOu may have to do a factory Reset to get the 655 back to 192.168.0.1 , then you can go through and do the IP change so you know what it is running on.
