NETGEAR Ultra-High Speed Cable Modem DOCSIS® 3.1 for XFINITY® from Comcast, Spectrum® & Cox® (CM1000-100NAS)

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.

Description: Replaced my Optimum Ubee cable modem with the Netgear CM1000v2. Have been paying for 300 Mbps speed but was only getting around 100 Mbps with the optimum modem. New modem has my speed back up over 300 Mbps. The modem switch was easy with optimum after finally connecting with a human technical support person.

Our old Netgear router finally died after 7 years. These things work really hard and 7 years is impressive. Got this one delivered via Walmart . Connected it. Called our ISP and gave the MAC address. Online in minutes. Get the speed our ISP promised.

great modems I have two. they both work great with optimum

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 only issue I had with this modem is that it didn't come with a built-in router. It was very frustrating to set up the modem, then have to run to Walmart again to buy a router. I slapped myself and vowed to stop others from making the same mistake.

I was expecting it to be nNghthawk compatible. It isn't. I should have researched better. While it works with Nighthawk router it doesn't communicate with the Nighthawk App.

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.

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.

Horrible product that was DOA on arrival and Walmart returns won't take it back and said I have to reach out to seller directly. Seller does not respond to any correspondence. Absolutely horrendous.
