Q: QuestionIs the Netgear CM1000 cable modem compatible with Time Warner/Spectrum?(9 answers)
A: AnswerI'm currently using it with TWC.Answered by JustJ
Q: QuestionWhat is the best Wi-Fi router to pair with this to obtain the highest Wi-Fi speeds?(6 answers)
A: AnswerThe nighthawk x6s ac4000.Answered by Anonymous
- A: AnswerAs 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.

Q: QuestionDoes this work with COX? Is this the best model and brand for COX?(7 answers)
A: AnswerYES. 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.Answered by Steve
- A: AnswerYes. I currently have an Ooma Telo connected to mine without any issues.

Q: QuestionIs this compatible with Optimum services?(3 answers)
A: AnswerYes, this unit is compatible with Optimum services.Answered by CommunityAnswer
Q: QuestionIs this unit compatible with Xfinity / Comcast? Will I also need a cable box?(5 answers)
A: AnswerKem, 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!Answered by Danny
Q: QuestionDoes this modem work with Suddenlink? If so, what has been your experience? Thanks!(5 answers)
A: AnswerI 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.Answered by 1256

Beats Spectrum modem
I got this due to my Spectrum modem always failing. So after initial hookup (super easy) there was a big difference. Speed was most notable. I went from an average 150 to 200 gbps to an average of 350 to 450 depending on time of day. I've had no outages or interruptions liked the old. Such a good idea of getting my own modem. This operates smoothly and no issues what so ever.

Works good
I purchased this on 1/26/2021 because I had an ARRIS SB6190 that was running into the Puma bug very bad. I had no issues activating it on suddenlink. Ran a Speedtest and am getting way better results than the arris 6190. I have the 1 GB internet plan from suddenlink
