Product Details
NETGEAR Nighthawk CM3000
2.5G DOCSIS 3.1 Cable Modem • Multi-Gig Ethernet • Link Aggregation
Next-generation cable throughput with a dedicated 2.5G port—built to scale with multi-gig ISP tiers and premium WiFi 6E/WiFi 7 routers.
Multi-Gig Cable Edge for Connected Homes
The Nighthawk CM3000 is engineered for modern DOCSIS 3.1 networks with mid/high-split support, enabling access to the latest multi-gig cable plans from major U.S. ISPs. A dedicated 2.5G Ethernet port provides a high-bandwidth handoff to your router or mesh system, while dual Gigabit Ethernet ports deliver additional wired flexibility with optional link aggregation.
Purpose-Built for DOCSIS 3.1 Performance
DOCSIS 3.1 Mid/High-Split Architecture
Designed to align with next-generation cable plant upgrades, DOCSIS 3.1 improves spectral efficiency and throughput. The CM3000 supports robust channel architecture to help sustain performance during high-demand hours.
Dedicated 2.5G Ethernet Uplink
A 2.5GBase-T RJ-45 port provides the preferred path to multi-gig routers and mesh systems, enabling your LAN to actually consume multi-gig service tiers. Pair with a WiFi 6E or WiFi 7 router to maximize coverage and device concurrency.
Dual Gigabit Ethernet + Link Aggregation
Two additional Gigabit Ethernet ports provide wired flexibility. When supported by your router and configuration, link aggregation can combine the Gigabit ports into a higher-capacity logical connection for resilient wired throughput.
ISP Compatibility & Cost Efficiency
Compatible with major U.S. cable providers for straightforward provisioning and reduced recurring costs. Not compatible with cable bundled voice services.
Key Features
A multi-gig modem stack designed for speed tiers, device density, and uptime
Up to 2.5 Gb/s Download Support
Built to unlock multi-gig service tiers for bandwidth-heavy homes—simultaneous 4K/8K streams, cloud backups, and large downloads.
2.5GBase-T Router Uplink
A dedicated 2.5G Ethernet port ensures your router/mesh can actually ingest multi-gig internet—reducing WAN bottlenecks.
Dual Gigabit + Link Aggregation
Use the dual Gigabit ports independently or aggregate for higher-capacity wired connectivity (configuration and router support required).
Optimized for Streaming & Gaming
Designed for low-latency, high-throughput usage patterns—VR/AR, competitive gaming, video calls, and smart-home workloads.
Eliminate Monthly Modem Rental Fees
Own your cable edge and reduce recurring costs while maintaining a scalable performance foundation for your router stack.
Router Required (No Built-In WiFi)
Purpose-built as a modem only—pair with your preferred WiFi 6E/WiFi 7 router or mesh for maximum coverage and control.
