Netgear announced today the latest Orbi WiFi 6 Tri-band Mesh System with DOCSIS 3.1 Built-in Cable Modem (model CBK752). As the name suggests, this is a mesh built specifically for cable Internet.
It's a matter of convenience
Generally, you can use any mesh system with any Internet connection. For example, you can combine the Orbi RBK752 and one of the recently-announced Netgear modems and have the same result as the CBK752. In fact, a slightly better one.
That's because, at the core, the CBK752 is essentially the RBK752, which is a lesser version of the RBK852. But generally, Netgear's Orbi Wi-Fi 6 sets are more similar than they are different.
What makes the CBK752 unique is its built-in DOSIS3.1 cable modem. Specifically, the router unit of the new mesh system is a cable gateway, or a "Cable Modem Router" as Netgear calls it. After that, it shares the same Obi satellites as those of other Orbi Wi-Fi 6 sets.
So, the CBK752 is the Wi-Fi 6 version of the CBK40 that came two years ago. It's a matter of convenience, you have both a modem and a router in a single box and therefore can cut down the number of wires and physical hardware pieces.
In return, keep in mind that the new mesh will only work with a cable Internet plan. The gateway unit has a cable (coaxial) service connector instead of a WAN port. Consequently, it won't work with any other broadband connection, such as DSL or fiber.
Orbi CBK752: Hardware specification: Multi-gig Internet ready
Netgear says the 's built-in cable modem can deliver up to 10 Gbps of download speeds thanks to the support for DOCSIS 3.1. However, it's backward compatible with older cable standards.

Just like the Wi-Fi 5 version, the CBK40, the new CBK752 works with all popular cable providers in the U.S. Its actual Internet speed will depend on availability and your Internet plan. Most importantly, keep in mind that the system's Wi-Fi speeds cap at 1.2Gbps, at best.
Availability and pricing
Netgear says the Orbi CBK752 WiFi 6 Tri-band Mesh System with DOCSIS 3.1 Built-in Cable Modem is available today with a retail price of $599.99 for a 2-pack, or about $150 more expensive than the standard version (RBK752).
Those living in a small home can also get just the gateway unit (CBR750) for $449.99. In any case, you can add more satellites at a later time.
