NETGEAR Nighthawk DOCSIS 3.1 Mid/high-Split Cable Modem (CM3000) – Approved for Today’s Fastest Speeds - Works with All Providers Incl. Xfinity, Spectrum, Cox - for Plans up to 2.5Gbps

I recently upgraded to the NETGEAR Nighthawk CM3000 DOCSIS 3.1 cable modem, and it has been an exceptional performer for my high-speed internet needs. Here's my experience: Pros: Supports Top-Tier Speeds: This modem is approved for cable plans up to 2.5Gbps, making it perfect for today’s ultra-fast internet and future-proofing for years to come. My speeds are consistently reliable, with no dips or interruptions, even during peak hours. Broad Compatibility: It works seamlessly with all major cable providers, including Xfinity, Spectrum, and Cox. Activation with Xfinity was a breeze, taking only a few minutes to get up and running. DOCSIS 3.1 Technology: The mid/high-split support ensures better upstream and downstream capabilities, making it ideal for heavy internet users like gamers, streamers, and remote workers. Compact Design: The sleek, vertical design saves space and blends well with my other networking equipment. Cons: No Built-In Wi-Fi: This modem doesn’t include Wi-Fi capabilities, so you’ll need a separate router for wireless connections. For me, this wasn’t an issue since I paired it with some other routers Price: It’s a bit pricey compared to some other modems, but the performance and future-proofing make it worth the investment.

The modem replaced a SB8200 on Spectrum and the firmware V6.01.03 is correctly working on Spectrum. The modem works great and is fast. It is VERY tall/large compared to other non-WiFi standalone modems. The admin page to see signal levels and logs is very annoying to get to work on a PC browser and it is highly recommended to check this page on a mobile device browser. The info provided in the cable connection diagnostic admin page is ample and should satisfy most users for signal diagnostics. The advanced administration tab Event Log provides identical information the Arris models show and is the same a Spectrum tech would have access to with their Scope software for their provided modems. I'm happy with the performance of this modem overall, but as stated already a few nitpicks is the overall size of the modem and the wonky desktop browser access of the admin gui page... really strange.

Such a great upgrade from my previous Modem. I can actually receive the Gig speed I'm paying for. Setup was easy, great instructions included. We have a rural cable/internet company the connectivity was seamless. This modem was mid-range price wise in the research I did, but so far, I consider it a great value.

Really the best cable modem I’ve ever used. Even though I subscribed to Comcast service at 500 Mb down I’m getting close to a gig, 940 Mb down. Stable and reliable.

Possibly the worst cable modem I have ever installed. Installed easily enough but I have over 18 wired and wireless security creameries using both proprietary software and micrsoft edge to view and after setting up this modem the cameras would not work. I am a retired IT with over 40 years experience in security camera install and this had me thrown. Put my old netgear c700 modem back in and all is good. This is the second Netgear mid split I have tried and both have been disappointing.

It works preety seamlessly with XFinity Internet. While it's rated for up to 2 Gbps, XFinity only rates it for up to 1.2 Gbps on their service (though that may just be them trying to get you to rent their garbage hardware). It has a 2.5 GbE port (which is backwards compatible with a standard 1 GbE Ethernet port on the other end) as well as 2 separate regular 1GbE port that can be turned on for LAGG (requires a device on the other end that understands and is configured for LAGG also) so you can do dual channel if you don't have a 2.5GbE port on the device at the other end (or a 10GbE port and Cat 8 Ethernet cable if you have hardcore network setup). You do have to manually enable the LAGG ports in the settings, otherwise they act like regular individual ports (multiple ports on a modem cannot have multiple client devices connected). Speed on a 1GbE connection is excellent without any overheating or hiccups. It runs extremely stable too, it hasn't had to be reset at all in the > 1 month I've been using it.

It’s very good with my nighthawk RS600 router

My Motorola MB8611started having recurring internet drops. After much troubleshooting with my ISP (Cox) it became pretty clear the ISP, while not perfect, was not the cause of the recurring/daily signal drops (multiple times a day). I decided to do a Modem Swap out; sorry I waited so long to make the change. I purchased a CM3000 to replace the MB8611, change was noticed immediately. Great speeds (+2 Gbps download) and no drops in last 2 days. Super easy install and great User Interface to check modem status, SNRs, etc. Highly recommended product!
