DHCP

So I have been running into some issues with my Nighthawk router. I have a Nighthawk MR60 and I keep having lag and I checked the logs and it appears that the router is sending DHCP reservations every 10-15 seconds to the same device:

This is just a small export from the log. The log was filled with entries like this constantly over a 24 hour period.

    What Firmware version is currently loaded?
    What is the Mfr and model# of the Internet Service Providers modem/ONT the NG router is connected too?

    I think the attached devices area of the router's admin page can give some text about an IP address (sometimes a name), but basically I'd try turning off various internet devices until that message goes away.  Then try to update it, or maybe set it up again (clear the settings).
