That is not a DOCSIS 3.1 capable modem, that is only a DOCSIS 3.0 modem. A DOCSIS 3.1 modem is required for the new ultimate package or higher (gigablast).

Yes, I knew it was not 3.1 despite being bonded as such. So why was it omitted from certification for 500. Your answer is simply that it’s DOCSIS 3.1. Can I get the Full technical answer instead of the quick reply? Should my current ASUS modem be green in denoted color for down and up instead of blue then?
Secondarily, I would upgrade to Gigablast and buy a new modem if 3.1 fully supported symmetrical up & down. You stopped doing fiber to home, so no sense in paying for Gigablast “light” until things improve for upstream.
no it's not bonded 3.1....probably why not certified.

Interesting compared to this information @ https://www.cox.com/residential/support/asus-cm16.html
RECEIVE Flashing Scanning for downstream channel. Verify all cable connections and try resetting the modem. Solid Green None. The downstream channel is connected in DOCSIS 3.0 mode. Solid Blue None. High speed Internet connection with downstream channels in DOCSIS 3.1 mode. SEND Off Upstream channel inactive. Verify all cable connections and try resetting the modem. Flashing Scanning for upstream channel. Verify all cable connections and try resetting the modem. Solid Green None. The downstream channel is connected in DOCSIS 3.0 mode. Solid Blue None. High speed Internet connection with downstream channels in DOCSIS 3.1 mode. This appears to be a misprint on the Cox site. The CM-16 is a DOCSIS 3.0 modem and the blue lights probably mean that multiple channels are bonded, not that it's running in DOCSIS 3.1 mode (which would be impossible since it is a DOCSIS 3.0 modem).
Even though this modem supports "up to 686 Mbps", it's generally not a good idea to use any DOCSIS device at more than 50% of its rated maximum speed. This is why it doesn't work on a 500 Mbps plan.
it's blue since boned 3.0 you need d3.1 since that's what cox requires
