Power on the UP Side is low, something to ask the ISP to see if they can raise it some. 

 

What game services are you connected too? 

 

Has a factory reset and setup from scratch been performed since last FW update? A complete pull of the power adapters for a period of time after the factory reset then walk thru the setup wizard and setup from scratch with a wired PC and web browser. Recommend setting the default DHCP IP address pool range to the following after applying and a factory reset: 192.168.#.100 to 192.168.#.200.

      See lots of Criticals that indicated a signal problem on the ISP side of the modem. ISP should review and resolve these and if Warnings or Errors are seen in the logs as well.

        Do you have any splitters, amplifiers, or filters in the coax line upstream of your CAX80?
