    1. Unfortunately, Jonathan, Optimum only recommends the three modems listed on their webpage. Optimum states there are many DOCSIS certified models that are compatible with Optimum, but they do not not list the model numbers. You should contact Optimum support to see if they can answer your question. The NETGEAR CM1150V may or may not work in your local region.

  1. I chatted with Optimum support today (unsure how “techy” the rep is but I have no way to know) about cable modems for use in Manalapan, NJ 07726 and here’s what he said :
    Any brand modem will work if it meets the following specs :

    minimum 16 x 8 channels
    maximum 32 x 8 channels
    DOCSIS 3.0 ( he said their network currently can’t detect DOCSIS 3.1 modems and they are working on it )

    He said Arris & Netgear are “recommended” brands. When I asked why brand is important, he said it’s not important. Just that their customers usually buy those. Another rep told me in Sep 2019 that 32 x 8 channel modems may have issues and hence 24 x 8 channels were recommended. When I mentioned this to today’s rep, he said that didn’t matter.

    So….Although their “approved” modem list has only 3 models all being Arris, any brand should work with Optimum. Another Optimum rep told me this in December.

    1. Thanks, Prasad, for this highly-detailed post. It seems like Optimum would update their approved modem list to include more modem models than the three that they list. Maybe only certain modem models work in certain regions. Hopefully, Optimum, will update their official approved modem list in the future.

      Thank you again, Prasad, for sharing this knowledge with everyone.

  2. Today I was told that Arris and Motorola were the recommended brands (with a short list of model numbers), but that any DOCSIS 3.0 should work. When I asked about DOCSIS 3.1 he said that they have not fully tested any of them, but in theory 3.1 is downward compatible with 3.0 and “should probably work”.

    I found on the Netgear site documents that indicate the CM1xxx series being compatible with Optimum, so I think I’m going to try the CM1200.
