Introducing WiFi 6—the latest generation of WiFi that delivers four times better performance than AC WiFi. With innovative technologies, such as Orthogonal Frequency-Division Multiple-Access (OFDMA)§, 4×4 Multi-User MIMO, and intelligent scheduling, WiFi 6 delivers a huge boost in speed and total capacity. Rising to the challenges of modern smart home demands, this new standard of WiFi is ready to support more devices with better reliability and faster speeds.

Ultra-High Speed Connections with DOCSIS® 3.1

DOCSIS® 3.1 offers a huge jump in download and upload internet speeds, supporting up to 10 Gbps download and 1 Gbps upload speeds. Since the technology is backwards compatible, upgrading to a DOCSIS® 3.1 modem means you’ll still enjoy your current internet service and be ready for the fastest speeds available in your area when your service provider upgrades to DOCSIS® 3.1.

The NETGEAR Nighthawk® App makes it easy to set up your cable modem router and get more out of your WiFi. With the app, you can install your router in few steps – just connect your mobile device to the router network and the app will walk you through the rest. Once set up, you can use the intuitive dashboard to pause Internet on your connected devices, run a quick Internet speed test and much more.
