NETGEAR Cable Modem DOCSIS 3.0 (CM700-1AZNAS) Compatible with All Major Cable Providers Including Xfinity, Spectrum, Cox, for Cable Plans Up to 800 Mbps

This Cable Modem is a Winner
I bought this cable modem after some study and evaluation of popular cable modems for sale. I decided to buy it because I don’t like the preset configuration of the Spectrum cable modem that comes with the Spectrum subscription. I prefer one that is not pre-configured and I’m glad I bought my own cable modem now that I have it.I went to the Spectrum website to find pre-approved modem models that are compatible with Spectrum equipment (you can do this with any cable company). I found that there are a lot of modems that are compatible, and I selected one based on the speed of my account and the price. I run about 300 MB/s speed, so I selected the Netgear Cable Modem model CM700 because it’s rated for at least 400 MB/s and the price was very reasonable when compared to the competition.I was pleased with the CM700 right out of the box. It’s much smaller than most other cable modems, and like most, it’s mindlessly easy to hook up. It has a power plug that goes to a 110 volt AC outlet, a cable plug that goes to the cable outlet on the wall, and an ethernet plug that can plug into a PC, or a router/wireless router, or even into a network switch (gigabit switch).Once I took the CM700 out of the box, I looked at the quick-start guide, and I had the CM700 set up and running in less than a minute. I tested it, and it gives great speed too. The CM700 plugs into my wireless router (the uplink plug). It feeds the wireless router and a PC that is wired directly to one of the wireless router ethernet output plugs. The wireless speed I get from this set up is excellent, and the direct-connect speeds I get exceed my expectations. Look at the pictures, and you’ll see from the quick-start guide how easy the CM700 sets up.The only criticism I have of the CM700 is that it seems to run warm, but then again, it has no malfunctions whatsoever. Also, I’m guessing that it has a great internal heat-sink, and I see that it has lots of holes for air ventilation, so that keeps it within the operating temperature range.Overall, I rate the CM700 a 5 star unit, based on both performance and price.

Had it for about 2 weeks no issues…BUT
UPDATE 08/23/2019 – I got this modem because I wanted to upgrade my internet and just have my own modem. Well it seems that, according to the Spectrum tech, it wasn’t compatible with the speed that I was getting (400/20). While I have my suspicions about that, they don’t charge me for the modem anyway (at least here in LA), so I opted to go with their modem and return this one. It didn’t really give me any issues but that doesn’t account for its longevity. If you want peace of mind from the PUMA 6 chipset, go with something else, but in my short experience, I had no issues with it.Got it installed today, had a wee bit of trouble activating it, but was Spectrum’s fault. Once it was activated, it ran as expected. I pay for 100/12. I get 118.46/11.80. About one megabit faster than my usual of 117Mbps upI heard about the PUMA 6 debacle and how much it can cause a lot of latency. My modem happens to be a hardware version 2.0. not sure if that means that it’s not Puma 6, but I ran the online test (Google Puma 6 Test) and it seemed to be well within nominal ranges. So I might have lucked out and got a version that doesn’t have the PUMA 6 chipset. So, you may be rolling the dice here, since others report that they indeed received a unit that does use the PUMA 6 chipset. If you want to be sure, go to the test page and check, return it if it’s mostly red. Check my screenshot for reference.I’ll update as time goes on.
