Multiple streams, no waiting

MU-MIMO (multi-user, multi-input, multi-output) allows simultaneous streaming to multiple devices, so everyone in a large home can have glitch-free access to the internet at the same time. Each stream takes on a portion of your home's overall wireless traffic, reducing or eliminating lag and buffering, for smoother, faster performance with streaming devices.

Tough security

This satellite offers 128-bit AES encryption with PSK. And built-in NETGEAR Armor™ (subscription required) provides anti-virus and data theft protection for your PC, Mac® and mobile devices. Security features can be accessed via the convenient Orbi app.

Product Research


WiFi Cable Modem Router: NETGEAR's CBR750 (AX4200) WiFi Cable Modem Router combines a DOCSIS 3.1 cable modem and WiFi 6 (802.11ax) Mesh router in one device, so you can connect to your cable internet service provider and other network devices in your home without having to connect a separate router or gateway. The NETGEAR CBR750 is certified by most major cable Internet providers in the US. The WiFi cable modem router saves you money over time by owning your cable equipment and avoiding monthly rental charges from your cable internet service provider.

US Cable Internet Service Provider Compatibility: The CBR750 WiFi Cable Modem Router is compatible with most major US cable internet service providers; like XFINITY, Spectrum, Cox, and Comcast. The cable modem supports the assignment of IPv4 and IPv6 addresses by cable Internet providers. Not compatible with Cable bundled voice services.

  • You must contact your Internet service provider (ISP) and tell them that you are using the cable modem. Before you connect the cable modem and contact your cable Internet provider, collect your cable account number, account phone number, and login information (your email address or user name and password).
  • If Comcast XFINITY is your cable Internet provider, setup Internet service by using Comcast XFINITY self-activation process. If you are unable to self-activate your modem router, call Comcast XFINITY customer service.
  • Not compatible with Verizon Fios, AT&T, Cable bundled voice services, or fiber internet services.

CableLabs DOCSIS 3.1 Certified: DOCSIS 3.1 offers a huge jump in download and upload internet speeds, supporting up to 10 Gbps download and 1 Gbps upload speeds (with 32 downstream & 8 upstream channels). 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.

Note: Maximum speed is derived from DOCSIS 3.1 specifications and actual throughput varies depending on your Internet subscription with your provider.

Powerful Quad-Core Processor: A 1.4GhHz quad-core processor provides reliable internet access, as well as efficiently handles wired and wireless network traffic for streaming Ultra-HD videos, listening to Hi-Res music, high-speed online gaming, and faster downloads.

Tri-Band WiFi: Simultaneous dual band WiFi provides two separate WiFi bands that work simultaneously. Simultaneous dual band WiFi technology reduces interference for better connections to more WiFi devices with fast download speeds up to 4.2Gbps.

  • 5GHz (ax): 802.11 a/n/ac/ax, 1024 QAM support, up to 2.4Gbps
  • 5GHz (ax): 802.11 a/n/ac/ax, 1024 QAM support, up to 1.2Gbps
  • 2.4GHz (ax): 802.11 b/g/n/ax, 1024 QAM support, up to 600Mbps

WiFi 6 (802.11ax): The NETGEAR CBR750 offers the latest generation WiFi 6 (802.11ax) technology, providing greater capacity to handle more devices on your network and speeds up to 6.0Gbps, ensuring that you can enjoy blazing fast Internet connections on all your devices. WiFi 6 is the latest generation of WiFi that delivers 4x better performance than WiFi 5 (802.11ac)for a huge boost in speed and total capacity. This new standard of WiFi is designed to support more devices with better reliability and faster speeds. WiFi 6 is also backward compatible with earlier WiFi generation devices (including 802.11 a/b/g/n/ac).

  • Multi-User MIMO (MU-MIMO):  Using Multi-User MIMO technology, the NETGEAR router can stream data to multiple devices simultaneously. 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.
  • OFDMA with Intelligent Scheduling: Orthogonal Frequency-Division Multiple Access (OFDMA) enables efficient data scheduling so that more transmissions can be sent at the same time, resulting in an impressive capacity increase in your network. This increased or available bandwidth allows you to add more devices to your network. The CBR750 supports uplink and downlink OFDMA to efficiently use air-time with better frequency reuse, reduced latency, and increased network efficiency. This is extremely useful for latency sensitive applications such as virtual reality (VR), augmented reality (AR) and Internet of things (IoT) sensors.
  • 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.

Wired Connections: The CBR750 modem router provides one coaxial cable connector to connect to your ISP and four 10/100/1000 LAN Gigabit Ethernet ports to connect local network devices.

  • Coax Connector: The modem router's coax connector plugs into your cable internet service provider's coax cable.
  • 4 Gigabit Ethernet Ports: The four RJ-45 Gigabit Ethernet ports (10/100/1000) with auto-sensing technology let you make a wired connection to local LAN devices, like your computer, game system, smart TV, and Blu-ray player. The CBR750 supports port aggregation so you can combine two ports for faster LAN transfer.

Antennas: The CBR750 features six internal antennas with high-power amplifiers, providing up to 3000' of WiFi coverage.

Orbi App: The Orbi App (for Apple iOS 13.0+ &Android OS 5.0+) makes it easy and intuitive to setup and use the NETGEAR CBR750 Cable Modem Router. With the Orbi 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. At the end of installation, an easy to use overview screen provides quick way to see what your network credentials are so you don't have to write it down on a piece of paper. The overview screen also shows you all connected devices and links you to helpful support information related to your router.

Notes: You can still use web-based installation wizard to install the CBR750 by visiting from your mobile device or a PC connected to the cable modem router.
