Nighthawk Modem Router Comparison

speed rating

Edge: NETGEAR Nighthawk WiFi 6 Cable Modem Router

The NETGEAR Nighthawk WiFi 6 Cable Modem Router (CAX80) offers a higher speed rating of AX6000, delivering up to 6Gbps of combined wireless throughput. This makes it suitable for larger homes or households with many high-bandwidth activities. In contrast, the NETGEAR Nighthawk Cable Modem WiFi 6 Router (CAX30) provides an AX2700 rating, offering up to 2.7 Gbps. While both support WiFi 6, the CAX80’s superior speed rating allows for better performance when multiple devices stream 4K video or game simultaneously without congestion.

coverage area

Edge: NETGEAR Nighthawk WiFi 6 Cable Modem Router

Coverage is a key factor when choosing a mesh-capable or single-unit router for your home. The CAX80 is designed to cover up to 2,500 square feet, providing broader reach for medium to large-sized homes. The CAX30 covers up to 2,000 square feet, which is sufficient for smaller apartments or compact houses. If your living space exceeds 2,000 square feet, the CAX80’s extended coverage ensures more consistent signal strength in distant rooms, reducing dead zones compared to the CAX30.

device capacity

Edge: NETGEAR Nighthawk WiFi 6 Cable Modem Router

The number of connected devices you can support simultaneously affects network stability. The CAX80 supports up to 30 concurrent devices, making it a better choice for households with many smart home gadgets, laptops, and mobile phones. The CAX30 supports 25+ connected devices. While both handle typical family usage well, the CAX80 provides additional headroom for growing networks. If you plan to add more IoT devices or stream on multiple screens at once, the higher capacity of the CAX80 offers greater long-term flexibility.

number of ports

Edge: NETGEAR Nighthawk WiFi 6 Cable Modem Router

Wired connections are vital for gaming consoles, desktops, and smart TVs. Both units include four Gigabit Ethernet ports for standard wired devices. However, the CAX80 adds a 2.5 Multi-gig LAN port and a USB 3.0 port. The 2.5 Gbps port allows for future-proofing if your ISP plan exceeds 1 Gbps, and USB 3.0 enables local storage sharing. The CAX30 lacks these extra ports, sticking to standard Gigabit Ethernet only. For users needing faster wired speeds or USB functionality, the CAX80 is the clear winner.

compatibility

Edge: NETGEAR Nighthawk WiFi 6 Cable Modem Router

Both routers are compatible with major cable providers like Xfinity, Spectrum, and Cox, and both are incompatible with Verizon, AT&T, and DSL services. The CAX80 is optimized for cable plans up to 6Gbps, while the CAX30 is approved for plans up to 1Gbps. If you have a high-speed plan exceeding 1Gbps, the CAX30 will bottleneck your connection, whereas the CAX80 can fully utilize faster tiers. For standard plans under 1Gbps, both devices perform similarly in terms of ISP compatibility and activation requirements.

Which NETGEAR Nighthawk modem router suits you

You want the highest possible wired speed

Our pick: NETGEAR Nighthawk WiFi 6 Cable Modem Router

The CAX80 features a 2.5 Multi-gig LAN port, allowing for connection speeds up to 2Gbps when using port aggregation. This exceeds the CAX30's standard Gigabit Ethernet ports. If your internet plan exceeds 1Gbps, this multi-gig capability ensures you do not bottleneck your wired connections for gaming or large file transfers.

You need broader wireless coverage area

Our pick: NETGEAR Nighthawk WiFi 6 Cable Modem Router

The CAX80 specifies coverage for up to 2,500 square feet, which is larger than the CAX30's 2,000 square feet rating. Both use dual-band WiFi 6, but the CAX80's higher AX6000 speed rating and larger coverage area make it a better fit for larger homes where you need consistent signal strength in every room.

You want a simpler setup for standard speeds

Our pick: NETGEAR Nighthawk Cable Modem WiFi 6 Router

The CAX30 is designed for cable plans up to 1Gbps and covers 2,000 square feet. It includes four Gigabit Ethernet ports and supports 25+ devices. If your internet plan is under 1Gbps and your home is smaller, this model provides sufficient AX2700 WiFi 6 performance without the complexity of multi-gig ports.
