  • QuestionIs this modem 1000mb? The pic of box say up to 6gb? The netgear page says the new 3.1 standard is capable of 6gb or 6000mb. The Aries DOCSIS 3.1 model says it can do up to 10g. So how can this only be 1000mb?

    Asked by Anonymous.

    • Answer As of right now, there are no consumer grade cable modems that are able to feed your network with anything more than Gigabit Ethernet. Having a modem that is theoretically capable of 6 Gigabit connection to your ISP is useless, as you cannot get the data out of the modem that fast. My sister and I both have the CM1000 modem and get spectacular speeds due to its ability to bind up to 32 downstream channels which allowed my Comcast technician to do some magic and get us both on nearly unused channels in our respective neighborhoods (as far as I understand). The 3.1 DOCSIS standard is great news for those of us that only have cable internet available to us, and will likely be implemented as the cable companies move to IPTV systems. The extra channels and speed your modem is able to bind will be used for your phone and television service. The CM1000 I can recommend without reservation, as my speeds through the ISP modem were around 180 (I'm paying for 200), and the speeds through the CM1000 are 250 or above. Hope this helps.

  • QuestionDoes this work with COX? Is this the best model and brand for COX?

    Asked by Tyrone.

    • Answer YES. I have COX and have used Netgear and Arris modems without issue. I recently upgraded to Gigablast internet and bought the Netgear CM1000. It has worked perfectly for the few weeks I have had it with no issues. You just need to call them or chat, they will ask for the serial number and MAC address so they can provision it, and in a few minutes you'll be online with your new modem. There are really only a handful of Gigabit-capable docsis 3.1 modems available, and the CM1000 has the highest consumer ratings of the three I looked at, which is why I bought it. For future reference, Cox has a compatible modems list on their website.

  • QuestionIs this unit compatible with Xfinity / Comcast? Will I also need a cable box?

    Asked by Kem.

    • Answer Kem, This absolutely works with Xfinity and any other major cable providers. You're also future proofing yourself by getting a modem that supports DOCSIS 3.1. As for the cable box question, you will not need a cable box to work with this modem, it takes a pure cable connection and negotiates the internet connection itself. You will need a cable box for any TVs you want to watch cable TV on. Hope this helps!

  • QuestionDoes this modem work with Suddenlink? If so, what has been your experience? Thanks!

    Asked by JFRT.

    • Answer I bought this modem so I could upgrade my internet speed with Suddenlink. My old modem would only go to 200 - and it often was much slower resulting in a lot of buffering and lost connections. I upgraded to 400 and the modem works great. It is combined with an Eero system in my house and I could not be happier. No more buffering and I have quite a few devices on the network. I knew the Eero system was not the issue. The new modem fixed the problem. If you buy the modem you have to call Suddenlink to get it activated.

  • QuestionIs this compatible with verizon fios?

    Asked by AO.

    • Answer Sadly, no, FiOS is a fiber optic based system, and from the last conversation I had with a Verizon tech, the ONT (outside box) is only allowed to talk to Verizon's own gateways inside the house. If you are not getting your full paid for speed for your FiOS service, you can call Verizon and request that they replace your gateway with the latest model. Another nice feature about the FiOS gateway is you can turn off all if it's routing, DHCP, and wireless function and get yourself a high performance router with multiple radios, beamforming tech, and the internal horsepower to handle lots of devices. I use the Netgear Nighthawk X6(?) model R8000, and it does a wonderful job of figuring out which devices should be on which radio. This is important, because wireless radios will step down their speed to the slowest standard device on any given radio. The R8000 has 3 radios, so my fastest/newest devices are all on their own radio and run at full capacity. Also, a little tip, if you are having range or dropout problems, move your wireless device to the 2.4 GHz radio, it will have longer range and better ability to penetrate walls and other obstacles. The speed difference is very rarely noticeable unless you are doing giant file tranfers within your own network. Hope this helps.
