  1. I’m thinking of purchasing my own modem. When I spoke with Optimum and asked if they could recommend a modem they told me to call NetGear. NetGear recommended the Nighthawk CM1150V. Is this compatable with Optimum? I have telephone, TV and 1gig internet with Optimum? I have my own router, a NetGear Orbi.

    • Since the NETGEAR CM1150V is not on the Optimum approved modem list, there is no guarantee it will work at your address. The CM1150V is only approved for Comcast’s phone service and no one else. But you can contact Optimum and give them your address to determine if you will be allowed to use the CM1150V.

    • No, the ARRIS TM1602 won’t be capable of hitting 1 Gig speed; it can get close to 1 Gig speed, but you will need a DOCSIS 3.1 modem to reach the fastest speed tier. The ARRIS TM1602 is only a DOCSIS 3.0 modem.

    • Hello Zachary,

      Was there a particular ISP (internet service provider) in mind? You likely can’t choose your own ONT; you get what the ISP gives you in most cases.

  2. Hi,
    I have a small cable company in Wyoming that provides modems to our customers (approx 600) free of charge. I would like to start replacing the current dcp3010’s with a 24ch or 32ch docs3 non-wifi modem. Do you have a list of those modems that don’t have puma chip sets? Any suggestions, Reliability and cost are most important factor.
    Thank you!

    • You can use the Cox approved modems list (over 90 modems listed) to see all the 24 and 32-channel modems. Ignore the modems listed with an * as those are DOCSIS 3.1 modems and ignore the black diamond modems as those contain the defective Intel Puma chipsets.

      Going through that list, there are only 3 models that fit what you want.

      Motorola MB7621 best option

      NETGEAR CM600

      TP-Link TC7650

      There some WiFi modems on the list. Unfortunately, most 24 and 32-channel modems contain the bad Intel Puma chipsets.

  3. Your Comcast page says they haven’t approved of the TP-Link TC-7620 for internet access, but the Amazon page you link to says they do. And I’ve used this hardware with their service multiple times now. Worked fine.

    I looked up their “My Device Info” page to look at compatible modems. It listed my hardware, and it doesn’t have any kind of unapproved value on it. Yes, their rated speed is lower than a 16×4 might be… “Up to 370 Mbps”. But is that why it’s not approved on your Comcast page (with a red X)?

    My recent speed test gave me just under 300Mbps down, and 25 up.

    • Hello Joe, the TP-Link TC-7620 is approved for Comcast. The red X refers to the purple header at the top of the table indicating that the modem does not offer VoIP or WiFi capabilities. Thanks for the question.

    • Yes, the NETGEAR AX6 is compatible with WOW!, however, the AX6 actually refers to a few devices. But they are all routers. Penny, you can use any router with an internet provider. Only modems are specific to certain ISPs.

  4. The first modem you show as approved is the Motorola MB8600 with a link to purchase on Amazon. But your full list of modems has two big red “X”s next to this model. Is it approved for my Breezeline WiFi, or not?

    • Yes, the Motorola MB8600 is approved for Breezeline. The red X indicates that the device does not have WiFi capability; you will need a separate router if you need a wireless internet signal. The purple table headers are explained underneath the table. Thanks for the question, Lisa M.
