NETGEARNighthawk DOCSIS 3.1 Mid/high-Split Cable Modem (CM3000-1AZNAS) – Approved for Today’s Fastest Speeds - Works With all Cable Providers, Incl. Xfinity, Spectrum, Cox - Cable Plans up to 2.5Gbps

I own an Arris TG862G modem for many years now. At the time, this was the approved model for VIOP phone lines. At $200 it has paid for itself many times over. Due to retirement living on a fix income, cost cuts were needed so I dropped the Triple Play and now subscribed to internet (Blast - 800Mbps). Recently I keep getting email from Xfinity says my modem (DOCSIS 3.0) is outdated and keeping me from getting my maximum download speeds promised by my plan. After so many of these notices, I decided to take the plunge and get a new DOCSIS 3.1 cable modem. I decided on the Netgear model CM3000-1AZNAS.Installation was easy. I already had downloaded the Xfinity App on my phone. It has a place to activate new equipment and recommended because you lose your internet. The switch over took about 10-15 minutes. I had internet in no time. The problem lay in that Speed Tests didn't reveal any, and I mean any gain in speed. So not wanting to admit I just spent $300 for nothing, I contact them with chat. I explained that I just installed a new modem and no change. Perhaps my modem (account) needs provisioned to accommodate the new modem. He tells me he can get me a higher speed package for less than I paying. So from 800 to 1100, when I wasn't even getting the 800. But less money is better so I agreed, thinking this would surely provision my account to the 1100Mbsp. Well after a day, still no change. I don't think it is this modem's fault, but Comcast's fault. I will try CS one more time. The moral of the story, "If it ain't broke, Don't try to fix it!"

I had an aging CM 700 from Netgear. It was very good, but the recent storms had made it somewhat unreliable I replace With the new CM 3000 it is fantastic. It can push and pull beyond the limitations of my Internet service provider. It pairs exceptionally well with a Netgear nighthawk RS 700 S Wi-Fi seven router. Blazing fast Wi-Fi for many devices. I run both devices on an uninterruptible power supply. We may lose electricity for aI run both devices on an uninterruptible power supply. We may lose electricity for a while, but the Internet stays up.

Worked Great - easy to install for a non-IT guy and works with Xfinity right out of the box.I have DREADED the idea of getting a new modem that was not directly from Xfinity because I thought it would be a huge hassle and involve a bunch of time on service calls.In the end, this was SUPER easy and I regret not doing it sooner. I recommend downloading any apps and confirming this modem through the Xfinity app before you swap. This way you have full internet before "going dark" during the swap over.This was direct plug and play and it's been fantastic, I would highly recommend.I paired this with TP-Link mesh routers and now I have great speed and coverage in my whole home. Should have done this long ago.

Since I purchased this item for over $200, I thought it would be a good product. It worked for about 3 weeks. Then, suddenly, it would not connect to the internet. Calling Netgear was not productive. They suggested it was my internet provider that was to blame. After calling my internet provider and having them come to my place to check cables and connections to diagnose the problem, I was told that it was the Netgear Nighthawk modem that was the problem. I called Netgear to get a replacement or trade. If you have lots of time and you are able to stay on the telephone for long menus and wait times, I congratulate your patience. This run-around from Netgear was extremely frustrating. They do not honor their warrantee so forget that you even saw that statement on their paperwork that they send with the unit. I called Netgear several times and when my call was transferred to another person, their phone system took me back to the first long drawn-out menu. I would only have to call back to start the process all over again. Dont bother wasting over $200 of your money and your time with Netgear. Send it back immediately to Amazon. Netgear’s warrantee is false and misleading. There is no warrantee. Netgear’s customer support is very poor. Don’t expect any. Netgear’s products are something I will never buy again.
