Blazing Fast, Future-Ready Cable Modem for Xfinity

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 routersPrice: It’s a bit pricey compared to some other modems, but the performance and future-proofing make it worth the investment.

Solid modem

I haven't done any 'stress testing' with this. My connection is a mere 1gb upload (soon to be higher, though!)However, it works as intended and stays very cool, unlike past modems I've used. Easy to setup.

Works great with XFinity Internet

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.

Netgear is the new Lemon Company to AVOID

Do not buy this if you can help it. I bought this March 22, 2025 and by June it started having issues. Today, July 2, is the second day in the past few weeks I had to cold cycle it completely to get it to come back online. I am in the process of trying to get my card protection services to charge them back because its been less than 120 days. This is pathetic. If a good attorney wants to class-action Netgear over this by all means contact me. The last router I had from them still works, lasted over 5 years, and I only upgraded because I changed my service to 2.2gbps service. Shame.

Solid Modem

This works as advertised, Only 4 stars the previous one broke after 3 years. This could have been due to an Xfinity blunder, since it broke just as Xfinity was playing with the connection. But I have no way of knowing.I got it because it has voice capability (it is just an Xfinity packaging saving), so most will not be interested in that feature. The non-voice version I would guess, is just as good.Simple to set up (with Xfinity, at least). Not the cheapest, but it does supply the throughoput.In general, a perfectly good product.
