Like many modern routers, the Netgear Nighthawk AX4 Dual-Band WiFi 6 supports many features and tech. They improve your network's connectivity and security. The IPv4 uses 32-bit addresses, represented as four sets of numbers separated by periods (e.g. 192.168.0.1). The router also supports IPv6. This allows you to use the latest Internet Protocol. Gigabit Ethernet ports support data transfer rates of up to 1 gigabit per second (Gbps).

A Gigabit WAN port is helpful. It is useful when your internet plan supports high speeds. OpenVPN is available for many operating systems. These include Windows, macOS, Linux, Android, and iOS.

A well-positioned antenna can reduce interference and signal weakening. This leads to a more reliable connection. Many IoT devices, smart home devices, and older Wi-Fi devices mainly use the 2.4 GHz band. The 5GHz band provides faster data transfer speeds compared to the 2.4GHz band. This AX Wi-Fi router provides much faster data transfer rates. It is faster than older Wi-Fi standards. The top speed, 600 + 2400 Mbps, is the highest data rate the router can reach. It's the theoretical limit in perfect conditions.

WEP was the first Wi-Fi security protocol. But it is now seen as weak and easy to hack. The introduction of WPA2 (Wi-Fi Protected Access 2) improved upon WEP. It provides stronger security. The WPA3 (Wi-Fi Protected Access 3) is the latest Wi-Fi security protocol. WPS (Wi-Fi Protected Setup) provides an easy method. It connects devices to a Wi-Fi network.
