Design and Build
The Netgear Orbi CBK752-100NAS system consists of two white units: the main Orbi Cable Modem Router (CBR750) and a matching Orbi Satellite (RBS750). This design follows the modern, minimalist aesthetic common to many mesh systems, intended to blend into home decor rather than stand out as technical hardware. The integrated nature of the main unit is its primary design advantage, housing both the cable modem and the primary mesh router in one chassis. This consolidation directly reduces the number of devices, power cables, and interconnections required at the main internet entry point, leading to a cleaner setup. The system is designed for use in the United States only.
Performance and Features
Modem Performance and ISP Compatibility
The core of this system is its integrated DOCSIS 3.1 cable modem. This technology supports internet plans with speeds up to 4Gbps and is certified for compatibility with major cable providers. Specifically, the manufacturer states it is certified for use with Xfinity for plans up to 900Mbps download speed, and with Spectrum and Cox for plans up to 1Gbps download speed. This certification is crucial as it assures users the device will work with their service without compatibility issues, potentially allowing them to stop renting equipment from their ISP.
WiFi 6 Mesh Networking
The router component delivers WiFi 6 under the AX4200 classification, with a total wireless speed of up to 4.2 Gbps. It employs tri-band mesh technology, which uses one dedicated band for communication between the router and satellite to maintain a stable backhaul, leaving the other two bands free for client device traffic. This design is intended to manage connections for 40 or more devices effectively, supporting activities like uninterrupted streaming, HD video gaming, and web conferencing across a large area. The system is rated to cover up to 5,000 square feet with the included router and satellite.
Connectivity and Ports
The included components list a 2m Ethernet cable, indicating wired connectivity is supported. The specific number and type of Ethernet ports on the units are not detailed in the provided data. The connectivity technology is listed as both Ethernet and Wi-Fi.
Security and Software Features
Security is a highlighted feature. The system includes NETGEAR Armor software, which provides real-time protection for the WiFi network and connected devices against hackers and includes a VPN for added privacy. A 30-day trial of this service is included. The manufacturer also states that security features are enabled out of the box, supported by automatic firmware updates designed to ensure optimal performance and compatibility. Network management is handled through the Orbi app, which is intended to simplify setup and ongoing adjustments.
Setup, Support and Ownership
Setup is designed to be managed through the Orbi app. The integration of the modem and router should, in theory, simplify the initial installation process compared to configuring two separate devices. The manufacturer notes that if connectivity issues are experienced after setup, a power cycle of the unit is recommended, stating that most connection issues resolve within two minutes. For expansion, coverage can be increased by 2,500 square feet with each optional Orbi Mesh WiFi 6 satellite, which are sold separately. Support is available directly from NETGEAR via a provided phone number. The system benefits from automatic firmware updates.
What Owners Say
Overall owner feedback for this product is positive, reflected in its rating. Reviewers generally appreciate the combination of a modem and mesh system into one purchase, noting the convenience and space savings. The coverage and performance for large homes are frequently mentioned as strengths. Some users have reported experiencing connectivity issues that were resolved by following the manufacturer’s guidance to power cycle the equipment.

Who Should Buy It (and Who Should Skip It)
The Netgear CBK752-100NAS is an ideal choice for subscribers of Xfinity, Spectrum, or Cox cable internet who have a large home (up to 5,000 sq. ft.) and want to streamline their network hardware. It’s perfect for households with many connected devices that would benefit from WiFi 6 performance and mesh coverage, and for users who prefer an app-managed system with strong built-in security. It also suits those looking to avoid monthly modem rental fees. For more options on routers suited for large homes, see our guide on the best routers for large homes.
This product is not suitable for users with DSL, fiber, or satellite internet, as it contains a cable modem only. It should be skipped by those living outside the United States due to its region lock. Individuals in smaller apartments or with minimal device counts might find its capacity overkill. Also, those who prefer to customize their network with separate, individually chosen modem and router components may want to look at other setups. If your primary need is supporting an extremely high number of devices, our roundup of the best routers for multiple devices offers alternatives.
Final Verdict
The Netgear Orbi CBK752-100NAS successfully executes on its promise of integration. By marrying a capable DOCSIS 3.1 modem with a well-regarded Orbi WiFi 6 mesh system, it delivers a powerful, wide-coverage network solution in a simplified package. The certifications with major cable providers provide peace of mind, and features like tri-band backhaul, support for 40+ devices, and bundled security software make it a robust modern networking hub. Its design effectively reduces clutter and complexity at the setup point.
Potential buyers must ensure their internet service is from a compatible cable provider and that their home size aligns with the coverage area. The need to purchase satellites separately for expansion beyond 5,000 sq. ft. is a consideration for the largest properties. While some users may encounter minor hiccups requiring a reboot, the overall package offers a compelling value proposition for the right user by consolidating monthly rental fees into a single upfront investment and delivering high-end mesh performance. For those with gigabit plans, comparing it to other options in our list of the best routers for gigabit internet is recommended.
