What is the limiting factor for the number of connected devices?
I have an RBR750 with two satellites. Currently I have about 50 total devices connected (phones, computers, printers, TVs, IoT devices, etc.... It all adds up fast!) and I'm noticing that some of the...

My question comes down to this: What exactly is the bottleneck that limits the RBR750 to around 40 connected device?
Could you please post a link to this Netgear statement about "40 devices". I could not find such a statement on the official Product Data Sheet. What I did find is this statement:
My ancient RBR50 is putting along just fine with over 40 devices (most of them are idle or are IoT 'gizmos'). If my old router can support over 40, surely "4X" means "more than 50+".
Compare the processors:
RBR50 - Qualcom IPQ4019, 4 ARM Cortex A7, Clock Speed 171MH, 2 spatial streams
RBR750 - Qualcom IPQ8174, 4 ARM Cortex A53, Clock Speed: 1400MH
It will be nearly impossible to connect more than one Class C subnet (255.255.255.0) of devices, which amounts to about 253, including the router, satellites, and user devices. In practical terms, the "sky's the limit" on the 750 product line. The WiFi radio spectrum will saturage before the router does.
However (BIG drum roll), there are serious issues with connectivity in both the 750 and 850 product lines. New firmware was officially released for the 850 last week and (I believe) there is a "pre-release" version for the 750 that is going around for those brave souls who are desperate.
CrimpOn - The 40 device limit is on the main netgear home page, in the brief description of each current Orbi system. It's also on the specific product page, in the main product summary text: https://www.netgear.com/home/wifi/mesh/rbk753/
With prior routers, I've always assumed the limit was available IP addresses on the subnet, like you said. But until a recent "smart home" buying spree, I'd never really had more than 30 or so devices regularly connected. So I figured maybe I missed something with regard to what WiFi can support, or what can reasonably be expected of residential routers with limited processors and memory.

Absolutely correct, "for over 40 devices", plain as day. More impressive than "over 20 devices", which one would think is also correct.
Marketing literature is always amazing (to me).
A couple of years ago, there was a post on the forum from someone who claimed to have over 120 devices on the original Orbi. Surely the number of "devices" a WiFi system can accomodate must have some relationship to the usage these devices impose on the system and on the WiFi channel capacity. 100 smart plugs that together do not send 1mb of data a week is a lot different than 20 laptops playing World of Stupidity (or whatever).
My money is still on the Orbi firmware issues, not the hardware.
Hi CrimpOn, (and FURRYe38 , plemans )
Could you please point me to the pre-release for the 750 series.
Thanks in Advance,
Al

This is the one that I know of. I haven't tried it since my issues aren't too bad, yet. I'm kind of hoping it or something newer comes out as an official release soon. If not, or if my disconnections get worse, I may have to give it a go.
