Detailed Specifications
Netgear CM2500-100NAS - 2.5Gbps DOCSIS 3.1 Cable Modem
Overview :
The Netgear CM2500-100NAS is a high-performance DOCSIS 3.1 cable modem engineered to bridge the gap between multi-gigabit ISP tiers and local network infrastructure. For IT engineers managing branch offices, SOHO environments, or remote edge deployments, this unit provides a reliable, high-throughput gateway that eliminates the bottlenecks associated with traditional Gigabit ports. It features a dedicated 2.5Gbps BASE-T Ethernet port, ensuring that the full bandwidth of modern cable internet plans is delivered directly to the downstream router or enterprise firewall.
Built for stability and low latency, the CM2500 utilizes 2x2 OFDM(A) and 32x8 SC-QAM channel bonding to maintain consistent performance even during peak network congestion. As a "modem-only" device, it is preferred in professional B2B environments to avoid the double-NAT issues and limited security configurations often found in ISP-provided gateway combos. This allows for seamless integration with enterprise-grade security appliances from vendors like Fortinet, Cisco, or Ubiquiti. Deployment is streamlined via a web-based activation portal, making it an ideal choice for standardized remote office setups where high-speed connectivity is critical for VPN stability and cloud-based application performance.Key Features :
Integrated 2.5Gbps Ethernet port for multi-gigabit WAN.
DOCSIS 3.1 technology supports speeds up to 2.5Gbps.
Backward compatible with DOCSIS 3.0 32x8 channel bonding.
Certified for major US cable providers like Xfinity and Cox.
