What’s in the box

You’ll receive a router and two satellite extenders in the RBE873 kit, which is tailored to large residences. Everything is designed to work together out of the box so you can set up a single network spanning multiple floors and areas.

Design and Build

The Orbi 870 Series presents an elegant, modern design with high-performance antennas hidden inside the chassis. You’ll find the units unobtrusive on shelves or in corners, and the 360° antenna coverage helps provide even signal distribution regardless of furniture layout.

Physical footprint and finish

The devices aren’t tiny, but they aren’t bulky either — NETGEAR balances size and antenna performance here. You’ll appreciate the clean lines if you plan to keep them in visible areas rather than hidden in cabinets.

Performance

You’ll notice a big jump in theoretical bandwidth thanks to WiFi 7, and NETGEAR claims up to 21 Gbps to give you room for multiple 4K/8K streams, cloud backups, VR, and heavy gaming. In real life, you’ll get impressive throughput, especially when using wired connections or a wired backhaul.

Real-world throughput expectations

The headline number (21 Gbps) is an aggregate across multiple bands and ideal conditions, so don’t expect a single device to hit that number. You will, however, see clear improvements over WiFi 6 systems — lower latency and more capacity when you’ve got many simultaneous users or bandwidth-heavy tasks.

Tri-band Enhanced Backhaul

Orbi’s tri-band design dedicates a radio for backhaul traffic to keep device-to-router communication smooth during peak use. You’ll benefit most if you let the satellites use the dedicated backhaul or wire them with the 2.5 Gbps ports for nearly full-speed mesh connectivity.

Wired speed and ports

The router includes a 10 Gig internet port so you can make the most of top-tier ISP plans without becoming the bottleneck. Each unit also provides multiple 2.5 Gbps Ethernet ports (router and satellites) so you can connect gaming rigs, NAS units, or smart home hubs with fast, reliable wired links.

Coverage and Placement

NETGEAR advertises coverage up to 9,000 sq. ft., which aligns with the three-piece mesh design plus WiFi 7’s improved range and capability. You’ll get good penetration through floors and walls if you place devices thoughtfully.

Best placement strategies

Put the router close to your modem and spread satellites evenly, keeping them within a mid-range distance to both the router and the devices they’ll serve. You’ll want to avoid putting satellites in enclosed cabinets or behind large metal objects, and if you can wire them for backhaul, you’ll gain the most consistent performance.

Multi-device Management and Capacity

Handling up to 150 devices means you can connect your whole household — phones, laptops, smart TVs, IoT devices — without the network choking. You’ll notice smoother video calls and less buffering when many devices are active.

Handling heavy simultaneous loads

The Orbi 870 Series is designed for households where many people stream, game, and work at the same time. You’ll see benefits from WiFi 7’s improved channel utilization and the router’s ability to prioritize traffic for latency-sensitive tasks like gaming or video conferencing.

Security and Software Features

NETGEAR includes multiple security layers and automatic firmware updates to help you maintain a safer network. The system ships with a 30-day trial of NETGEAR Armor, and Advanced Router Protection helps keep you protected against threats.

NETGEAR Armor and Advanced Router Protection

With NETGEAR Armor, you’ll get anti-malware, anti-phishing, and identity protection features for devices on your network; the trial lets you test those tools before committing. Advanced Router Protection complements this by pushing firmware updates and security fixes automatically so you don’t have to remember to check.

Privacy and controls

You’ll manage parental controls, guest networks, and device-level permissions from the Orbi app, which puts most day-to-day security and management tools in your hands. The automatic update feature reduces the gap between vulnerability discovery and patch application, which improves overall privacy and safety.

Setup and Management

Setting up the Orbi 870 Series is intended to be quick and app-driven, with step-by-step instructions in the Orbi app. You’ll register the router, add satellites, and configure SSIDs within minutes if your modem and ISP are cooperating.

The Orbi app experience

The Orbi app guides you through initial setup and ongoing management, allowing you to check device lists, prioritize traffic, run speed tests, and update firmware. You’ll also be able to create guest WiFi, apply parental controls, and see basic security alerts all from your phone.

Quick setup checklist

You’ll want to do a few simple things before you start: ensure your ISP modem is connected and functioning, place your router centrally if possible, and have the Orbi app installed on your phone. If you plan to use wired backhaul, run your Ethernet cables before powering up the satellites to avoid redoing placement later.

Satellite Integration and Backhaul Options

You can use the satellites wirelessly or wire them with the 2.5 Gbps ports for a wired backhaul option. You’ll get the most consistent throughput and lowest latency when you use a wired backhaul, especially for high-demand areas like game rooms or home offices.

Wireless vs wired backhaul trade-offs

Wireless backhaul is convenient and still very capable thanks to tri-band architecture, but if you want closer to maximum speeds and minimum latency, wired 2.5 Gbps backhaul is preferable. You’ll need to weigh convenience against performance needs; wired backhaul requires Ethernet runs but pays off for critical devices.

Gaming and Streaming Performance

You’ll find the Orbi 870 Series well-suited for gaming, 4K/8K streaming, and VR thanks to both bandwidth and latency improvements. The dedicated backhaul and QoS features will help keep your gaming ping stable while others stream or video call.

Latency and reliability

You’ll see reduced jitter and improved packet retransmission behavior compared with older systems, especially when multiple high-bandwidth activities occur simultaneously. If you’re serious about competitive gaming, connect the console or PC via a 2.5 Gbps Ethernet port to get the best experience.

Compatibility and ISP Support

This Orbi kit works with most internet service providers and supports today’s fastest cable and fiber plans through the 10 Gig port. You’ll want to ensure your regional ISP supports 10 Gbps plans if you plan to use that port to its full extent, and note that it’s made for use in the U.S. only.

Modem and configuration notes

If your ISP provides a modem-router combo, you may need to place it in bridge mode to avoid double NAT, or you can keep the combo and configure the Orbi in Access Point mode for simpler setups. You’ll want to check with your ISP or NETGEAR’s support documentation for modem compatibility tips.

Setup Troubleshooting

You might run into a few common issues during setup, but most have straightforward fixes that you can perform from the app or the device interface. You’ll be guided through reboots, factory resets, or firmware updates if required.

Satellites won’t connect

If a satellite refuses to sync, power-cycle both the router and satellite, then attempt re-pairing in the app while keeping the devices within reasonable proximity. You’ll also want to check for physical obstructions or interference sources and consider wired backhaul if wireless linking remains unstable.

Orbi app won’t discover the router

Make sure your phone is connected to the router’s temporary WiFi or to the same network and that Bluetooth and location permissions for the app are enabled. You’ll also want to confirm the router’s LED indicates normal operation and that the modem is online.
