Design and Build
The Netgear Orbi 870 Series sports an elegant, new design that is a departure from some of its predecessors. The white units are designed to blend into home decor rather than stand out as technical gear. According to the manufacturer, this design houses high-performance antennas that provide exceptional 360-degree WiFi coverage. The system includes one router and two satellite extenders, all of which share a similar aesthetic for a cohesive look. The build is focused on facilitating the powerful internal hardware, including the fixed antennas and the array of high-speed ports on the rear of each unit. The physical design supports its core function: to be placed strategically throughout a home to eliminate dead zones.
Performance and Features
Wireless Performance and Coverage
The cornerstone of the RBE873-100NAS is its WiFi 7 capability. The manufacturer states it delivers speeds up to 21 Gbps, which is claimed to be 2.4 times faster than WiFi 6. This performance is enabled by tri-band technology, which includes a dedicated band for enhanced backhaul communication between the router and satellites. This is designed to ensure WiFi stays fast across all devices simultaneously, even when many are in use. The system is rated to cover up to 9,000 square feet and handle up to 150 connected devices, making it suitable for very large homes with extensive smart home ecosystems, multiple users streaming, gaming, and video conferencing at once.
Connectivity and Ports
This is one of the most striking aspects of the Orbi 870. It features a 10 Gigabit internet (WAN) port on the router, designed to unlock the fastest available cable and fiber internet plans. For wired connections, the system is exceptionally well-equipped. Each unit—the router and both satellites—has four 2.5 Gbps Ethernet ports. This provides a total of twelve high-speed LAN ports for connecting gaming consoles, PCs, NAS devices, or creating a 2.5 Gig wired backhaul between nodes for the most stable and fastest possible mesh connection. This abundance of high-speed ports is a significant differentiator for users with wired networking needs.
Software and Security Features
Setup and management are handled through the Orbi app, which is designed to simplify the process for any user, regardless of their internet service provider. For security, NETGEAR includes several built-in measures. The system supports the latest WPA3 security protocol and receives automatic firmware updates. It also comes with a 30-day trial of NETGEAR Armor, which is described as an all-in-one security suite offering protection against hackers, malware, and identity theft for all connected devices. This focus on integrated security is a key selling point for privacy-conscious users.
Setup, Support and Ownership
The manufacturer emphasizes easy setup via the Orbi app, suggesting the process is straightforward for most users. The system works with any internet service provider. In terms of support and longevity, the product includes automatic firmware updates and is listed as having security updates. It is backed by a one-year limited warranty. It is important to note the manufacturer specifies this product is made for use in the U.S. only. To achieve the full benefits of the WiFi 7 speeds, users will need both a compatible multi-gigabit internet plan and client devices that support the WiFi 7 standard, though it remains fully backward compatible with older WiFi devices.
What Owners Say
Based on the available data, the Netgear Orbi 870 Series holds a rating of 3.6 out of 5 stars. This suggests a mixed reception among early adopters. While specific buyer review excerpts are not provided in the data, such a rating typically indicates that while many users are satisfied with the performance and coverage, others may have encountered issues with setup, stability, or value relative to the high cost. Potential buyers should consider that as a cutting-edge WiFi 7 product, some early-adoption quirks might be reflected in user feedback.

Who Should Buy It (and Who Should Skip It)
You should seriously consider the Netgear RBE873-100NAS if you have a very large home (up to 9,000 sq. ft.) and are already subscribing to or planning to upgrade to a multi-gigabit internet plan. It is ideal for tech-heavy households with numerous simultaneous users for 8K streaming, competitive gaming, VR, and video conferencing, especially if you have or plan to acquire WiFi 7 devices. The extensive wired port selection also makes it perfect for users with many devices that benefit from a 2.5 Gbps Ethernet connection. For more insights on routers suited for large homes, see our guide on the best routers for large homes.
You should likely skip this system if you live in a small or medium-sized apartment, have a standard sub-gigabit internet connection, or lack WiFi 7 devices, as you will not utilize its full potential. Its U.S.-only designation also makes it unsuitable for international users. Those on a strict budget or who find the setup of a three-unit mesh system daunting may want to explore other options. If your primary need is leveraging a gigabit internet plan, our review of the best routers for gigabit internet may offer more tailored alternatives.
Final Verdict
The Netgear Orbi 870 Series RBE873-100NAS is a forward-looking mesh system that brings the raw potential of WiFi 7 into the home. Its standout features are the 10 Gigabit internet port and the plethora of 2.5 Gbps Ethernet ports, which are rare in consumer mesh systems and cater to a niche of power users with specific high-speed wired and wireless needs. The claimed coverage for 9,000 square feet and support for 150 devices positions it as a solution for the most demanding connected environments. The inclusion of robust security features and an intuitive app rounds out a comprehensive, high-end package.
However, this is undeniably a premium investment aimed at early adopters. To realize its advertised 21 Gbps speeds, you need both a compatible internet plan and client devices, which are still emerging in the market. The mixed user rating suggests that real-world experience may vary. For the right user—someone with a large property, a multi-gig internet subscription, and a desire to fully future-proof their network—the Orbi 870 Series is a powerful and capable choice. For the average user, it may be overkill. Exploring different categories of networking gear, like the options in our Tech Gear section, can help contextualize this product within the broader market.
FAQs
What is the main advantage of WiFi 7 in the Orbi 870?
The main advantage, according to the manufacturer, is significantly higher potential speeds—up to 21 Gbps, which is 2.4 times faster than WiFi 6. This is designed to reduce latency and increase capacity, benefiting applications like 8K video streaming, high-fidelity gaming, and virtual reality. It also introduces more efficient use of the wireless spectrum. However, to experience these gains, you need client devices (like phones, laptops, or TVs) that also support the WiFi 7 standard.
Can I use the 2.5 Gbps Ethernet ports on the satellites?
Yes. Each of the three units in the RBE873 system (the router and two satellites) is equipped with four 2.5 Gbps Ethernet ports. This allows you to connect wired devices like gaming consoles, desktop computers, or network-attached storage drives directly to any satellite, not just the main router, providing high-speed wired access points throughout your home.
Does NETGEAR Armor cost extra after the trial?
The product includes a 30-day trial of NETGEAR Armor. After this trial period, the service requires a paid subscription to continue. The specific subscription cost is not listed in the provided manufacturer data. The built-in security features like WPA3 and automatic firmware updates, however, remain active regardless of the Armor subscription.
Is the Orbi 870 good for gaming?
On paper, its specifications make it suitable for gaming. The high speeds, low latency potential of WiFi 7, tri-band design to reduce congestion, and multiple high-speed Ethernet ports for a wired connection are all beneficial for gaming. The ability to handle many devices simultaneously also means gaming traffic is less likely to be impacted by other household activity. For dedicated gaming setups, using one of the 2.5 Gbps ports for a wired connection would provide the most stable and responsive experience.
