Upgrading a RBR50 to RBE771
Is there an easier way to update the info into the new router without typing in all the reserved IPs and other common setting? I really don't want to add 60+ items one by one again.

One tiny piece of advice: Power up the new RBE771 and configure it without defining the WiFi network name (SSID). After those 60+ devices have been entered into the LAN Setup table, then you can power off the existing RBR50, connect the RBE771 to the ISP device (modem, ONT...) and set the WiFi credentials to exactly match those of the RBR50.
The reason is Netgear's implementation of DHCP. We humans expect that reserving an IP address for a device in the LAN setup table means that the router will always assign that IP address to the device. Alas, this is not so. If the RBE771 begins broadcasting the WiFi network before the LAN setup table is created, then every device in the house will detect it and immediately sign in. Having nothing in the LAN setup table, the router will randomly assign IP addresses to each device. If the device is powered off and back on later, the router ARP table will already have that IP address and the device will be given that IP address again. The only way to correct this is to power off the router (and disconnect every device in the house) and then power it back on again. and hope that no device in the house that is not in the LAN Setup table grabs one of those "reserved" IP addresses.

Sounds like a good plan.
I have run into the issue of assigning IPs after the fact and it is a slow process. The other thing I am still considering is if I should set up a loT network as well. It would be nice to isolate them to another band but probably not worth the extra quirks and setup that requires. And what is exactly loT and what is not. Most items are obvious but lots of grey area for other items.
