I don't know if this helps you all or not, but when my device is registering, it is doing so with the IP address of my router instead of the IP address I have assigned to it. It used to register with the assigned IP, but not anymore.
You will have to check and make sure you settings didn't get knocked out. Personally I leave mine set to DHCP but I removed the Linksys firmware from my WRT54GS V6 and installed DD-WRT. Using it I can specify this mac address = this ip so it always comes up correct. Perhaps your current firmware on your router has a feature like this or maybe you can replace it (the firmware)with something better.
