    • Mary, you will need to personally contact Atlantic Broadband to have equipment activated for you. Your personal info was redacted to protect you.

      This site deals with letting people know which modems are approved for each ISP (internet service provider).

  1. Is the NETGEAR CM1200 still in the approved modem list? Hard to find the information and hard to contact customer service. Also, do triple plays (with voice) need to be unbundled first before being able to use this cable modem, provided it is currently approved?

    • Yes, the NETGEAR CM1200 is approved for Atlantic Broadband service (here is Atlantic Broadband’s approved modem list). Keep in mind the CM1200 does not have phone capabilities, so you won’t be able to take advantage of your triple play bundle unless you are using a phone device from Atlantic Broadband. Just activate the new modem with your current plan; there should be no need to unbundle anything unless you want to delete services.

      Hope that helps, Roberto.

      • I called and Atlantic Broadband Tech support told me they do not have an approved list and they will not approve any type of modem, but the Tech Support Rep said if I give him a model number that he can let me know if he commonly sees it in use, he said the CM1000 he sees a lot… . I got the V2, they updated my Firmware on it so they support it, but I have had nothing but issues with connection interruption via MDD Message Timeout, ABB tells me signal is excellent and Netgear hasnt been able to resolve yet. Never had connection issues like this before. We’ll see if Netgear can resolve this weekend or I’m returning it for a Motorolla.

        • Hello Steve,

          Sorry about your connection issues. The tech rep lied to you. The Atlantic Broadband approved modem list is listed on their website (click the first gray box that says “What modems can I use with my Atlantic Broadband High-Speed Internet service?”). You often have to talk to multiple reps since they will likely give different answers depending on who you talk to at the company. Hopefully your issue gets resolved over the weekend.

          • I knew it sounded wrong when talking to the rep… I had the Arris SB8200, Motorola MB8600, and Netgear CM1000 written down when I called too, irritating when you do your homework and something like that happens… Your site had been very helpful!! Thank you! Unfortunately when I purchased my CM1000 I didn’t think V2 would be an issue and now Netgear is elevating me to a Sr Tech Rep, nothing but headaches — I’m tech savvy and done everything possible no splitters direct line in 10ft from box.

            Thanks again, maybe I’m just unlucky but V2 has not been a good experience, maybe something to keep an eye on.

          • Thanks for replying back, Steve. If others have problems with the NETGEAR CM1000v2, this page will be updated to stay away from that model. You may also have a bad firmware patch from Atlantic Broadband. Or maybe you have bad wiring to your home. If you can, you should return the CM1000v2 and try a different device.

            NETGEAR should stop creating different versions of their hardware; it is creating issues with ISPs and customers. If a company needs to create a different version of a modem (v1 vs. v2), they should create a whole new sku model. Someone else with a different ISP is having issues with the NETGEAR C7000v2. It seems NETGEAR’S v2 models are troublesome. Unfortunately, when ordering from retailers, you often are not told which version of the modem you are receiving. Sorry again for all your issues. Good luck, Steve!

  2. I have been having dropped connections with my Motorola MG7700 and my service tech said it may because it’s DOCSIS 3.0 – they swapped out the modem/router with a temporary one and I haven’t had any issues. I’m trying to figure out if I need to purchase a different modem or contact Motorola about the one I have being defective.

    • Kenneth,

      The Motorola MG7700 is not on the Atlantic Broadband approved modem list, so that could be the issue. It is okay if they activated it, but since it is not verified to work on the Atlantic Broadband network, you will likely run into occasional issues. The MG7700 is likely not defective. The suggestion is to only use modems on the official certified list for Atlantic Broadband.
