Q: Does this work with Spectrum Cable also I need a router and modem do they make one box that does both?

submitted by Rob N - 1 year ago

  • A: Actually it says Spectrum and Cox under the Spefications tab. Now I am curious as to which one is accurate.

    submitted byDavey2074 - 11 months ago

  • A: Hi Rob N, thanks for reaching out about Netgear Cable Modem - Black (CM1000-100NAS). This states it "works with XFINITY® from Comcast," but it does not mention Spectrum. However, the link below will work with Spectrum and is both the modem and router in one device. https://www.target.com/p/netgear-nighthawk-ac1900-wifi-docsis-3-0-cable-modem-router-c7000/-/A-50226308#lnk=sametab If you have any additional questions, we welcome you to contact MyTGTtech at 833-848-8324 every day, between 7am-11pm CST.

Q: How many square foot coverage

submitted by Walt - 5 months ago

submitted by Doesnt work with frontier - 11 months ago

  • A: Hi Doesnt work with frontier, thanks for reaching out about Netgear Cable Modem - Black (CM1000-100NAS) This model router may not work with your Frontier service as they primarily uses DSL as opposed to a cable internet connection like this modem/router.

Good Support (word filer)

I had some difficulties getting the modem to work (due entirly to the cable company) and the support group was very helpful. Since installation the modem has worked perfectly.

Working well!

The new DOCSIS 3.1 modem is a definite improvement over the 4 year old DOCSIS that I had. Easy to Set up. Much better for Zoom and YouTube streaming.

Works Find for My Internet Needs

I was appreciative that Netgear sent me an email letting me know it was time to update my router with a link to ensure I was getting the correct one that worked with Xfinity. Setup was easy and it’s working fine. Internet connection is good. No issues so far.

Staying with a proven performer

I have only been using the new modem for a week, but if past performance of my old CM600 is any indication, I should have years of issue free usage. I'll stick with Netgear until I have a reason to switch.

It works well so far

I had to buy another cable modem since my previous NETGEAR was no longer being supported. It cost a lot more than the previous one I bought, but I am satisfied.

My new DOCSIS 3.1 cable modem (CM1000)

I am a 71-year-old who is better at technical stuff than my husband, but was a bit concerned about adding this new modem to my former router. It was quite easy to set up and then when I contacted my Internet provider online via an app, it automatically connected my Wi-Fi. I was happy there were no glitches. My husband notices how fast the connection is compared to our former modem.

CM1000 Cable Modem

The modem was surprisingly easy and quick to set up and activate using the Xfinity app on my smart phone and the MAC address on the modem label. It took just a few minutes and has been working well.

Netgear modem DOCSIS 3.1

Modem was easy to set up. The only stumbling block was that there should have been more emphasis on the fact that my internet provider needed to be informed that I have a new modem and my account needed to updated to reflect that fact. This was an arduous process because I had to resort to these dumb chat services. What was finally accomplished could have been accomplished in half the time or less if I could've actually TALKED to Xfinity support. Otherwise the modem it self runs effortlessly as did the previous Netgear modem.

Easy replacement for old modem

I purchased the modem after getting an end-of-life warning for my previous NETGEAR modem -- and a nice discount. It was literally a drop-in replacement. Moved the cables over, gave Xfinity 15 minutes to provision it, and I was back online I'm getting about 150mb/s more on speedtests with the new modem than I was with the old one.

Fast and Easy Setup

The Netgear CM1000v2 is very easy to set up. The instructions included with the product are clear and helpful. After providing the serial number and MAC address to my service provider, activation was quick and seamless. I ran a speed test afterward, and the results were impressively fast! I’m very happy with this cable modem — it’s reliable, fast, and a great value overall.
