14 thoughts on “Charter Spectrum Approved Modems”

  1. I’m interested in the Motorola MB8600 but noticed that you have an asterisk (*) placed next to it?
    There isn’t a key glossary, so what does the asterisk mean?

    1. Sorry about that, Roberto. The asterisk means the Motorola MB8600 is a DOCSIS 3.1 modem. The page has been fixed. Thanks for bringing attention to that error. The MB8600 was just added to the Charter Spectrum approved modems list last month.

    1. Jeff, you are correct (page has been fixed – thank you). However, the NETGEAR CM1000 is approved under the Minimally Qualified Modems List. So, either version of the CM1000 will technically work, but Spectrum recommends against using modems on the Minimally Qualified Modems List.

  2. Trying to use ,c7800 night hawk by Netgear for gig service, says it’s a spectrum modem! Don’t see on list, it’s docsis 3.1 up to 10gigs! Huge download files from work and uploads various devices on the network at 1 time! So need to be able to work flawlessly and the spectrum hardware drops out!

    1. The NETGEAR C7800 is a minimally qualified modem for Spectrum meaning it has passed minimal testing to confirm that it won’t cause harm to Spectrum’s network. However, Spectrum doesn’t recommend using minimally qualified modems because they haven’t been tested to deliver your purchased internet service speed.

      You may want to purchase a modem that appears on the Spectrum approved modem list to reach your full internet speed. Also, avoid Intel Puma chipset modems.

  3. On netgear cm 1200 modem box claims it can be used with spectrums gigabit internet plan. I would like to use it for my gig plan. On different web sites some say spectrum will only let u use spectrums modem. I would like to have the answer to this before purchasing one of them .

    1. Hello Bobby,

      Spectrum allows customers to purchase their own equipment. The NETGEAR CM1200 is a minimally qualified modem, which is why it does not appear on the list above. A minimally qualified modem means it won’t cause harm to Spectrum’s network, but they haven’t tested the CM1200 to confirm its ability to deliver your purchased internet service speed. Though permitted for use on Spectrum’s network, they recommend against using minimally qualified modems.

      You can use the NETGEAR CM1200, but you may not receive the full internet speed you have purchased. It may be months or years before Spectrum fully approves the CM1200. Spectrum is notoriously slow for approving modems.

  4. looking to buy a new router voice modem router combo to replace mt arris tg1682,will the Motorola mt7711 work on spectrum the Motorola mg7700 is an approved modem but it does not have voice,ph jacks which i need..thank you hope to get a rapid reply.ty Alan

    1. Hello, Alan. No, the Motorola MT7711 is not approved for Spectrum. Currently, Spectrum has no certified voice modems on their Spectrum approved modems list. They do list these phone devices for use on their network. You should contact Spectrum to know what options you have for your local region. You may need to rent a device from Spectrum if you require phone service.

      Thanks for the question, Alan.

  5. Hi Alan. I have gigabit service through Spectrum currently, and am looking to switch my spectrum provided modem (Ubee e31u2v1).
    Which is recommended with confirmed gigabit speeds? I see the NETGEAR CM1000v2 and MOTOROLA MB8600 on your list — have they been confirmed to work up to the gigabit speed or just up to 400 mbp as far as you’re aware? It makes it hard since Spectrum hasn’t provided an approved list for gigabit service.


    1. Hello Joshua,

      Thanks for the question. Spectrum Internet Gig is only available in select markets. You need to contact Spectrum and verify with them if it is available in your local area with the modem you want to use to be sure you can achieve the speed you want. Per their website, any DOCSIS 3.1 modem on Spectrum’s approved modem list should get you to Gig speed if it is actually available in your area, Joshua.

  6. I need a Cable Modem for download speeds up to 400Mhz with Voice supported. Is the Netgear Nighthawk 1150V Cable Modem with Voice certified by Spectrum? If nor, what is an alternative cable modem w/ voice that I can use for speeds up to 400Mbps?

    1. Unfortunately, Michael, Spectrum does not have a voice modem certified on their approved modem list. Spectrum offers information on their voice modems page. Spectrum may provide one of these devices to you. You should contact Spectrum to see if this option is available in your location. Good luck, Michael.
