  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.
