    Rock-solid speed, flawless stability finally

    I’ve tried multiple modem/router combos over the years, and most of them promise high speeds but choke under real-world load. This one is different. I’m on Xfinity 2 Gbps plan, have a house full of smart devices, cameras, TVs, and heavy gaming/streaming happening at the same time – and the connection stays solid. No drops, no buffer, no overheating, and the upload speeds are noticeably faster than what I used to get with my older Netgear C7000v2. Setup was painless – literally plug in, activate through Xfinity, and done. It handles WiFi 6 perfectly, and I finally see consistent speeds on all floors of my house without needing mesh extenders. Zero hiccups during Zoom calls or Xbox online gaming. Price isn’t cheap, but if you’re tired of replacing weak equipment or paying rental fees for mediocre ISP devices, this is 100% worth it. It does what it claims – stable, fast, and reliable. Highly recommend.

    The Netgear CM3000 Modem Produces Blazing Speeds!!

    The Netgear CM3000 is an outstanding cable modem that delivers exceptional performance and reliability. Paired with the Orbi 870 series mesh system, it provides blazing-fast and consistent connectivity throughout the home. I’m consistently seeing download speeds around 2.3 Gbps and upload speeds near 300 Mbps, even with multiple devices running at the same time. I have a Xfinity 2 Gbps internet plan. The CM3000 easily handles a large number of connected smart home devices, streaming, gaming, and work-from-home demands without slowdowns and seldom drops. Setup is straightforward, and once running, it’s truly a “set it and forget it” modem. If you want multi-gig speeds and rock-solid performance with a high-end mesh system, the CM3000 is a fantastic choice.

    Best for Gig speeds

    I purchased this modem for my recent upgrade to Gig speed internet. Modem is working flawlessly and doesn't get hot. Only hiccup I had was during the initial setup. Despite being listed as preferred modem in my ISP's recommended modems list, I was having very hard time to initiate the signal transmission. But don't panic just make an appointment with their tech like I did. Prrocess went like a breeze and it's working fine and delivering close to 1Gbps and sometimes even over that too. Modem boots up within 1-2 minutes if you do a power reset. It has two ethernet ports that can handle Gig speed and one extra port that can be used for multi Gig internet. It's bit pricy but maybe one can wait for some time to get this on reduced price.

    200Mbps upload, a success!!

    This is what you need to access updated Xfinity internet speeds. I needed a modem that was approved for the 200 Mbps upload. I learned the hard way that even though a modem is capable, Xfinity has to approve it and they keep the list short. Whether this a way to force you to rent one of theirs…you decide. My current modem was a CM1100 that Xfinity no longer supported. I needed a modem that allowed link aggregation because the Orbi mesh router I have only has 1Gbps internet port and Ethernet so to access the 1.2Gbps I am paying for, I needed a second link. Surprised to find most modems do not have this. Keep in mind it has a 2.5Gbps internet port for those that have routers with the same. With the CM1100 and link aggregate I was getting 1250Mbps down and 40Mbps up. With the CM3000 and a single Ethernet, I am getting 900Mbps down and 220Mbps up. With link aggregate (two Ethernet setup) I am getting 1450Mbps down and 240 up. I took about 20 minutes to get it set up. I unplugged the old one and plugged in the new one to coax and power. After two rounds of letting the lights fully boot to solid, I used the Xfinity app to manually add the MAC address. There was a link below the internet modem status to add new equipment. I finally plugged in the Ethernet and powered up the router.
