Odd iPhone 16 behavior after Orbi 772 FW update
I received a new Orbi 772 system (with FW 10.5.18.3) about 3 weeks ago and the system appeared to be trouble-free until a few days ago, when I finally took the latest FW update (10.5.19.5). While mo...

While your symptoms are a little different than mine, it certainly could be related as these disconnects all seem to be banding issues - issues related to switching between WIFi 5, 6, 6E, and/or switching between router/satellites, etc.
The steps I took that seems to make it a lot more stable are:
1) If it's enabled, disable IPv6. There are issues, and Netgear knows and is working on it.
2) Set your device to have a manual IP address, outside the DHCP address range so there are no conflicts. Also set a manual DNS address - this can be your router (192.168.1.1), that's how I have it set. Just make sure both are manual.
3) on iPhone there is a setting "Private Wi-Fi address" - I have it on "fixed".
With those settings mine has been very stable - one flip to cellular/disconnect in 2 weeks; and that could have been anything. See if that helps your device(s) stay on an appropriate band, and let us know!

I will try these settings as soon as I have again access to the iPhone 16 (it is my wife's), but I know that IPv6 is disabled in the Orbi and, in the phone, "Private Wi-Fi address" is set to "fixed".
As for "setting the device to manual IP address", do you mean to have the Orbi LAN setup to "reserve an IP address" for this iPhone? Or is there some IP setting in the iPhone where you can set it to manual (but I don't remember seeing it)?
This iPhone 16 has been with us since way before I got the new Orbi. As I said earlier, before the recent FW update, this iPhone 16 was always at "5 GHz + 6 GHz" and connected to either the Orbi Satellite or the Orbi Router, depending on the phone location in the house, which I consider normal behavior.
Is it possible to revert the Orbi system (router and satellite) to FW release 10.5.18.3, when everything with the iPhone 16 was normal? Or is it a bad idea?
