Both share the same WAN Link Aggregation feature, where you can combine the WAN and LAN1 ports into a single 2Gbps WAN connection. This Link Aggregation feature is excellent when you use a supported modem and a faster-than-Gigabit Internet connection. https://community.netgear.com/t5/Orbi-AX/RBR850-frequently-issuing-DNS-REFUSED-responses/td-p/1926055 The Orbi RBK852 uses Qualcomm’s newest Networking Pro 1200 Wi-Fi chip with 1GB of RAM and 512MB of capacity for storing firmware and settings. It’s all powered by a quad-core processor that runs at a maximum of 2GHz. It has an AX6000 rating. Netgear Orbi AX4200's hardware looks quite sleek from the top. Pre-sync hardware, the familiar setup process Since my three-bedroom home is somewhat on the cusp of Netgear’s coverage recommendations, I tested the Orbi RBK763 in both two-node and three-node configurations. In both cases, the primary node was installed in my study, connected directly to the internet line and also (via Gigabit Ethernet) to an Asustor Drivestor 4 Pro NAS appliance.

Other than that distinction, from a Wi-Fi performance perspective, the RBK752 and CBK752 are the same. Keep that in mind if you're looking for a review of the Orbi CBK752. By the way, I might review the CM2000 modem separately when I manage to get a faster Internet connection.

By the way, if you wonder what each Orbi model number means, I explained that in this post about different home mesh brands.) Here are the results I saw, along with the speeds achieved by some other mesh systems in the same tests:

With a satellite connected 50-feet from the router on the same floor and the test system another 40-feet away, the RBK752 mesh network came up short with 87.7Mbps of data delivered to the test system. That’s roughly half the Linksys Velop AX4200 (161.1Mbps), although it’s a lot better than the Netgear Orbi RBK852 (39.1Mbps). The Eero Pro 6 kit was in between with 142.3Mbps of bandwidth. I do not think my household is special, in that we almost always use a lot of network products: several mobile phones, tablets and PC’s, wireless printer, three TV’s, various network players and wireless speakers. Smart doorbell, robot vacuum cleaner, blinds and garage door. Eventually, smart humidity meters, smoke alarms and district heating will also be installed. And it’s critical that everything talks together – and that it works! When speed was enough You lose some features from the top-end system, but the lower price and decent performance makes this a more reasonable system for many. Design and build quality – Gives you most of what you need but there are fewer Ethernet portsThis seemed better, but then at completely random times the Orbi wifi connections would drop. The base station was always okay, but the satellites kept dropping connections, so our zoom calls were interrupted, connections to online systems had to be restarted. There was no obvious reason, no change in traffic or movement of wireless devices, nothing we could see that was causing these drop outs. I myself have a lightning-fast fiber network with 1 Gbps, which feels redundant since I only get a tenth of that speed on the wireless connection. Therefore, I was reely looking forward to testing my first Wi-Fi 6 (AX) mesh network. This communicates in a more advanced way than older systems, in that several commands are sent and received simultaneously between routes and satellites (nodes). In addition to increasing the network speed of Wi-Fi 6 compatible gadgets, the home network will be more stable with older gadgets as well. Peace of mind guaranteed! In theory, at least. Nighthawk – with potential for improvement With just the RBR850 router set up, it moved 883.6Mbps to the receiving device 15-feet away. While this is off the pace set by high-performance routers, like the Netgear Nighthawk AX8 (RAX80) (at 1.389Gbps), it easily beat out other mesh kits, like the TP-Link Deco X20 (at 622.1Mbps) and the Arris SURFboard mAX Pro (at 820.3Mbps).
