Netgear CM600 firmware update

I just replaced my Arris SB6183 with a Netgear CM600 to try to resolve disconnect issues and to get 24 downstream channels.  My net connection is significantly slower now. The Netgear website says Cox has approved firmware version 1.01.14. Mine has V1.01.06 installed.  I called cox and the tech said they couldn't install firmware. She sent signals to the modem, but it didn't do anything. I'm the errors below with both modems. 

Can Cox update the firmware in CM600, or should I go back to the Arris and live with disconnects? Cox doesn't seem to know why they occur or how to fix them.

    Hi Jerry, it appears that version 1.01.16 was recently added to the Cox-approved list. We can try to push this firmware to your modem. This will interrupt your internet connection for several minutes while the modem is updated. When would be a good time to proceed? -Becky, Cox Support Forums Moderator

    Thank you Becky.  I just worked on line with a technician to update the firmware. 

    I'm still getting these errors:

      Hi Jerry, I suggest a service call so an on-site technician can further investigate. If you'd like my team to schedule an appointment for you, email your full name, address, and a link to this thread to cox.help@cox.com. -Becky, Cox Support Forums Moderator
