The Story
Future-proof your home network with the ultimate in cable modem technology.
The Netgear Nighthawk CM3000 is a next-generation DOCSIS 3.1 cable modem engineered to unleash the full potential of today’s fastest internet plans. Designed with revolutionary Mid/High-Split technology, the CM3000 is one of the few modems capable of supporting next-gen upload speeds (up to 1Gbps) from major providers like Xfinity and Cox.
Whether you are a competitive gamer demanding low latency, a remote worker needing crystal-clear video calls, or a household with dozens of smart devices, the CM3000 delivers a lag-free, multi-gig experience.
Top Features & Benefits
- Blazing Fast Multi-Gig Speeds: Supports download speeds up to 2.5Gbps and upload speeds up to 1Gbps, making it perfect for 4K/8K streaming, AR/VR gaming, and large file transfers.
- Mid/High-Split Technology: Unlike older modems, the CM3000 utilizes mid-split spectrum efficiency to deliver up to 10x faster upload speeds on supported networks (essential for content creators and cloud backups).
- Universal Compatibility: Certified for Xfinity (including "Next Gen Speed" tiers), Cox, Spectrum, and other major U.S. cable internet providers.
- 2.5G Ethernet Port: Includes a dedicated 2.5 Gig internet port to connect directly to your WiFi 6E or WiFi 7 router for maximum throughput.
- Link Aggregation Support: Features two additional 1G Ethernet ports that can be aggregated for even faster wired connections.
- Save Monthly Rental Fees: Stop renting inferior equipment from your ISP. Owning the CM3000 pays for itself in savings (typically saving up to $168–$300 per year).
- Compact & Efficient: A fanless, vertical design ensures silent operation and optimal cooling while taking up minimal desk space.
Why Upgrade to the CM3000?
1. The "Upload Speed" Advantage
Most cable modems are limited to slow upload speeds (often capped around 40Mbps). The CM3000 is specifically built to handle the new "mid-split" upgrades ISPs are rolling out, allowing for symmetrical-like speeds that redefine video conferencing and livestreaming performance.
2. Built for the Future of WiFi
If you have upgraded to a Mesh WiFi 6E or WiFi 7 system, an old modem creates a bottleneck. The Nighthawk CM3000 opens the pipeline, ensuring your expensive router actually receives the multi-gig speed you pay for.
3. Reduced Lag & Latency
Powered by DOCSIS 3.1 and OFDMA (Orthogonal Frequency-Division Multiple Access), this modem processes data more efficiently, significantly reducing ping spikes during peak usage hours.
Technical Specifications
| DOCSIS Standard | DOCSIS 3.1 (Backward compatible with DOCSIS 3.0) |
| Max Download Speed | 2.5Gbps |
| Max Upload Speed | 1Gbps (ISP dependent) |
| Ports | 1x 2.5G Ethernet, 2x 1G Ethernet |
| System Requirements | Cable Broadband Internet Service (Check with your provider for tier compatibility) |
Stop throttling your own internet. Upgrade to the Netgear Nighthawk CM3000 and experience the speed you’re paying for.
