A capable network multi-tasker

This router has fast Wi-Fi 6 built in. Built-in Orthogonal Frequency-Division Multiple Access (OFDMA) allows efficient simultaneous data transmission to multiple connected devices. And 160 MHz channel support increases speed to compatible mobile devices.

Tough security

The AX4 is protected by tough 128-bit AES encryption with PSK that denies outsiders access to your wireless signal. Plus, NETGEAR Armor™ offers additional tools and utilities that help keep you safe. If you have young ones around, use the router's parental controls to control their access, and filter out content you don't want them to see. The Nighthawk offers VPN support to keep your flow of information secure when you're working remotely. (Subscription required for some advanced features.)

Product Research


Overview: The NETGEAR Nighthawk AX4 (LAX20) WiFi Router with 4G LTE can provide home internet via a cellular connection along with simultaneous Dual-Band WiFi that can deliver combined WiFi speeds of up to 1.8Gbps. The AX4's powerful 1.5GHz quad-core processor gives you a high-performance networking engine for faster connections. Incorporating the latest WiFi 6 technology (802.11ax), the AX4 features proven high-performance while preventing lag spikes, drop outs, and high ping times for better gaming, 4K streaming, web-surfing, and more.

Note: The NETGEAR AX4 will require a paid data plan through a compatible service provider.

1.5GHz Quad-Core Processor: The NETGEAR Nighthawk AX4 utilizes a powerful 64-bit 1.5GHz quad-core processor to separate processes and prioritize high performance WiFi connections to get maximum combined WiFi speeds of up to 1.8Gbps, with up to 4 streams available. 160MHz channel support lets you enjoy 1Gbps WiFi speeds for fast streaming and downloading on newer mobile devices.

4G LTE: The AX4 features built-in 4G LTE for cellular-based internet service, and is certified with AT&T, T-Mobile, Verizon, and Clearway Wireless (Sprint not supported). The AX4 requires an activated nano-SIM card (4FF) to be installed for cellular communication and operation. After purchasing a data plan from your service provider, you can install an activated nano-SIM card from the provider, or use the included Clearway nano-SIM card for purchasing a plan through Clearway Wireless.

Dual-Band WiFi: Dual-band WiFi delivers up to 1.8Gbps combined WiFi speeds through 2 dedicated WiFi bands. Each band can operate simultaneously and provide up to 2 separate streams in the 5GHz band and 2 streams in the 2.4GHz band. Dual-band WiFi combined with the intelligence to segregate traffic based on WiFi speed provides the best performance for multiple WiFi devices in your home. Both bands are backwards compatible with 802.11 a/b/g/n/ac WiFi.

  • 5GHz (ax): 2x2 (Tx/Rx) 1024 QAM 20/40/80MHz, up to 2.4Gbps
  • 2.4GHz (ax): 2x2 (Tx/Rx) 1024/256 QAM 20/40MHz, up to 600Mbps

IPv6: The AX4 supports Internet Protocol version 6 and can be configured as such.

Dynamic Quality of Service (QoS): QoS resolves internet traffic congestion when you have competing internet demands at home. QoS identifies your online activities by application and device, then utilizes bandwidth allocation and traffic prioritization techniques to automatically allocate more bandwidth to latency sensitive applications like online gaming and video streaming. This ensures that lower priority applications continue to work.

Beamforming+ (Explicit & Implicit): Beamforming+ boosts speed, reliability, and range of WiFi connections on the 2.4GHz and 5GHz bands. Unlike typical WiFi routers that just blast the WiFi signals in all directions; with Beamforming+ (Explicit), the router actively tracks connected devices and directs power to the router antenna closest to the client device. With Beamforming+ (Implicit), the router can use information from client devices that support Implicit Beamforming for even greater WiFi speed, reliability, and range.

Multi-User MIMO (MU-MIMO): MU-MIMO capability allows you to simultaneously stream up to 2 devices at the same time on the 5GHz band and 2 on the 2.4GHz band. With MU-MIMO, your WiFi network can deliver faster throughput to every MU-MIMO connected device. That means faster downloads and smoother streaming for your devices.

Gigabit Ethernet Ports: Five Gigabit Ethernet 10/100/1000 ports (1 WAN & 4 LAN) allow you to connect multiple wired devices. The WAN port is used to connect your internet modem, while the LAN ports are used to connect your local network devices.

Nighthawk App: The Nighthawk App for iOS and Android devices makes it easy and intuitive to setup and use the NETGEAR Nighthawk AX4 router. With the Nighthawk app, you can install your router using very few steps - just connect your mobile device to the default network, and the app will walk you through the rest. The app automatically updates the router to the latest firmware, allows you to personalize your WiFi network, and even help register your router with NETGEAR. The intuitive Nighthawk app dashboard lets you monitor your home network from most anywhere, check broadband speeds from your service provider, pause the internet to any connected device, track internet data usage, and setup separate networks for guests.

Notes: You can still use the web-based installation wizard to install the router by visiting from your mobile device or a computer connected to the router.

NETGEAR Armor: NETGEAR Armor is a subscription-based security service that's powered by Bitdefender, a global leader in cybersecurity. NETGEAR Armor protects your home network from potential cyber threats and provides complete data protection, advanced threat defense, parental control, webcam protection, multi-layer ransomware protection, anti-phishing, safe files, secure browsing, rescue mode, anti-fraud, and anti-theft. NETGEAR Armor provides you with multiple performance and privacy tools that can be viewed and configured on PC, Mac OS, iOS, and Android devices.

Note: NETGEAR Armor requires a paid subscription after the initial 30-day free trial period.

VPN: The AX4 router lets you create a VPN (Virtual Private Network) to securely access your network via the internet when you are not at home. The VPN feature must be enabled on the router and you must install and run VPN client software on the computer you are using to access the network.

USB Port (ReadySHARE): A single USB 2.0 port on the router can be used to connect a USB storage device such as a flash drive, hard drive, or printer. The router works with most USB-compliant external flash and hard drives (if your USB drive uses special drivers, it is not compatible). You can share data that is stored on most common USB storage devices across your WiFi network with ReadySHARE USB Storage Access. ReadySHARE lets you access and share a USB drive connected to the router's USB port. The AX4 can also be used as a ReadyDLNA media server, letting you view movies and photos on DLNA/UPnP AV-compliant media servers, such as Xbox360, Playstation, and NETGEAR media servers. You cannot connect computers, USB modems, CD drives, or DVD drives to the router's USB port.

Memory: The NETGEAR router features 512MB of flash memory and 512MB of RAM.

Antennas: The AX4 features 2 built-in WiFi antennas that can be tilted and swiveled for the best WiFi performance and coverage. Two additional rear-panel antenna connections can be used for optional TS9 antennas (not included).

Controls: A front-panel WiFi button let you power the WiFi radios On/Off. A second front-panel WPS button lets you connect to WPS-enabled devices. Corresponding LEDs for each will light when that feature is active. The rear panel includes a main Power button, for turning the 4G LTE router On/Off. Additional front-panel LEDs include:

  • Power: Indicates whether router is On or Off.
  • Internet: Lights when an internet connection is ready.
  • 2.4GHz/5GHz: Two LEDs can light to indicate that that corresponding WiFi radio is operating.
  • 1 - 4: Four numbered LEDs display which LAN port(s) are being used and their Ethernet connection (10/100/1000Mbps).
  • USB 2.0: Indicates if a USB device is plugged into the rear-panel USB port, and if its connected.

Mounting Options: The NETGEAR router can simply be placed on a flat-surface table-top or it can be wall-mounted using its integrated keyhole slots (mounting screws not included).

System Requirements: Make sure your home network meets the following system requirements.

  • Operating Systems: Microsoft Windows 10 / 8 / 7 / Vista / XP / 2000, Mac OS, UNIX, or Linux.
  • Internet Browser: Microsoft Edge, Google Chrome 55 or higher, Firefox 45 or higher, Safari 10 or higher.
