Updated 25 days ago · Based on the Amazon listing and published specifications, not hands-on testing.
A tri-band mesh kit that covers a large home with wired ports at every unit and a dedicated wireless backhaul. Ports top out at gigabit, so multi gig internet plans will not reach full speed.

Overview
Owners of large or multi floor homes get a tri-band mesh system made of an Orbi router and satellites that hand devices off as they move. It plugs into an existing modem and replaces the current router, managed through the Orbi app.
A third radio band carries traffic between units, so satellites do not halve the speed reaching far rooms. The gigabit ports cap wired and internet throughput, and the security suite terms differ between listing sections.
Who it's for
Families in big houses who need steady WiFi in every room and wired ports near TVs and consoles. Small apartments do not need a mesh kit at this scale.
Pros and cons
- Very large coverage area
- Dedicated band for backhaul
- Ethernet ports on every unit
- Expandable with more satellites
- Gigabit ports cap multi gig plans
- Satellite count not stated in listing
- Security trial terms inconsistent
Performance notes
Satellites talk to the router over a separate band, which preserves speed for devices instead of splitting airtime. Placement still matters: satellites need a strong link to the router to pass full speed onward. Wired devices are limited to gigabit per port.
