Netgear CM600 vs Netgear Nighthawk CM1200

So far, after several hours of testing, the speed seems to be stable. The speed is maintained between 320Mbps to 350Mbps with the Time Warner extreme plan. The reason why I am giving this 3 stars is because it was not an easy install for me. It took me 3 hours to mate this thing with my Apple Time Capsule router

However, there are multiple choking points in your home that will bottleneck your internet connection, such as a cable modem and wireless router that ...

that said, once connected to the router, all was well. Good speed, stable connection, but runs a bit warm. Other than that setup glitch, so far, it's all good

Have not needed any technical support, and even then I'm at least a little savvy so I know what to do when there is a problem amiss. Every time I have had an outage that a reboot can't fix, the culprit was usually the ISP, and they usually sort me out in about 5 or so minutes, or, if they can't sort me out, they usually tell me to just wait it out and I'm usually running again once the ISP side outage is clear, so shout out to Spectrum support for being so helpful even though I am running this modem and not a Spectrum product. It has been basically an "ol' faithful" since the day we got it and it handles 3 Xboxes, 4 TVs, 4 phones, and a tablet all having internet access AT ONCE without breaking a sweat in most cases. It works like a champ and is a good product
