NETGEAR Nighthawk DOCSIS 3.1 Cable Modem CM1000, 1 Gbps, Gigabit, Guided Set Up, 1 Gig Port, Xfinity/Spectrum/Cox

Netgear representative in another country asked myself and the Spectrum technician at my house about 40 questions, after telling us he did not understand what the problem is. He was rude and demeaning. Then told me it was working just fine and I did not need to change anything. It was not working although the package says that it should.

I've been looking for a modem for a while and doing so much research. I am so happy I picked up this Netgear modem because it instantly gave me 4 times faster speeds than what I had. No more disconnected internet or hard installation. This is the best option ever! You saved my life and the gamers/podcasters in the house are finally happy!

The Netgear gig speed modem has received the highest consumer ratings. It is delivering far superior data speeds when compared with my old modem. The price I paid through Walmart.com was at least 10% lower than through other online retailers. Overall, I am completely satisfied with my online purchase.

Everything works great, but to be honest I can't tell if it's any faster. I got this cable modem because the coverage ran out on my router, so I figured I may as well upgrade both. The connection was fairly easy, but I had to contact Xfinity. The instructions said I could do it online, but that turned out to not be the case. I was pleasantly surprised that the first person I talked at Xfinity knew what to do. The whole process took about an hour but would have been less had I just called Xfinity right away. I did have an issue with the TV picture after everything was up and running. I had the previous cable modem behind the TV, and it didn't affect the picture, however, I had to move this modem a few feet away. It sits on the floor about three feet below the TV and there's no interference.

I replaced my Netgear CM 500 with the Netgear CM 1000 as the 500 was very updated and could no longer get further updates. without changing my Wi-Fi at all, I went from 50 megs to 200! Everything runs smoothly… I'm thrilled (I was not thrilled with how difficult Xfinity made this to activate!)

Title: Giga good Description: Recently had a lightning storm that cooked my router (not Netgear). I've used Netgear switches in the past and have never had problems with them so I decided to try a Netgear modem. It was easy to setup and has been handling everything the network been able to deliver. Lately we've been seeing 940 MBs pretty steadily. Haven't had to do a re-set other than once when a firmware update was applied. Simply put- it does its job quietly and efficiently in the background like it was designed to do. I was surprised at how cool the unit runs. The previous cable modem ran pretty hot. I'm pleased.

I needed this quickly after a nearby lightning strike torched our good and reliable CM600 we've used for years with Xfinity. I figured I might as well upgrade, and the newer modem, which supports the latest DOCSIS standards and provides other changes, has given us a decent improvement most of the time. However, it's really finicky about cable power levels, and our Xfinity/Comcast service is often on the margin. Some days, the CM1000 will restart frequently due to a reliable enough, but not top-tier cable signal. Since our current max throughput from the provider is 400-500 Mbps, which the CM600 also supports, the upgrade hasn't gone as well as hoped. When the connection from Xfinity is stable, we get great throughput. Max out what we can get with the current ISP. However, when the connection status is just 'acceptable,' we may drop a lot, and the rest of the Family Unit doesn't care about an extra 100-200 Mbps if it's not connected at all. My recommendation is that if you are with Xfinity and have a plan in the 400 Mbps range, the CM600 is just fine and more reliable than the CM1000. For other ISPs, it may be a massive upgrade.

The Netgear CM3000 modem solved a problem I had streaming 24 bit / 96 kHz hi res audio files where music would stop after a track or two and not advance to the next track. This problem was with the Netgear CM1200 which I bought in 2024. Not a bad router, Internet speed was decent, ~950 mpbs on my Xfinity 1100 speed plan and I could stream video files fine. But high res audio is different b/c the files are not cached. I figured the CM1200 was contributing to a data latency issue and packets were getting jumbled. The CM3000 was Xfinity recommended (which means they'll push firmware updates to it) so I bought it. It has a little smaller form factor than the CM1200 which is nice. Setup using the Xfinity phone app was a breeze. Solved my high res audio file latency issue immediately. I'm a happy camper.

The modem works as claimed and meets all performance needs. I had a problem with it getting on line. I called the help line and determined that the problem was with the ISP. They had to do something on their end to get the ISP and the modem to communicate.

My cable company said they couldn't see it on line. It was a waste of time and money. I need to ship this back.
