Quick way to re-enter your IP reservations after factory reset
Many of us hesitate much to go for factory reset mainly because of the load of repetitive work you need to do to restore your IP reservations especially if you have many such reservations.
An easie...

I am not confident that "saving configuration" would be of much use in my situation, because the ways that my Orbi is disappointing me have appeared since an automatic firmware upgrade and I have continued to enter new device reservations. At this point, I suspect that "something is amiss" that only a reset to factory would address, and I have avoided doing that because of the prospect of typing in all those MAC addresses.

Completely agree. usually why I choose to do a factory reset is that I suspect a data corruption somewere and a backup/restore will just get me back to where I was.

In addition to device reservations, the NVRAM dump also includes lines like this:
orbi_dev_name12=24:92:0E:31:52:FA Dicks New Tablet
The numbers do not match the "reservation" numbers. Any idea if this is something that could be entered with Telnet commands, or will it propogate automatically?

The entry orbi_dev_name12=24:92:0E:31:52:FA Dicks New Tablet is the "Device Name" that you can edit in the "Attached Devices" list below (in the blue box):
You will also find another entry with the same MAC address like this
orbi_dev_name_ntgr9=24:92:0E:31:52:FA Samsung Tablet that corresponds to the device type (the red box) in the snapshot above.
The numbers do not match. The system uses only the MAC address to match the different entries with each other.

And.... I presume that changing the device reservations to be in order by IP address would not cause a problem, since the "factory reset" creates a totally empty table. (This is one of my other disappointments with Orbi firmware: that we cannot sort displays by column. This would not help the "attached devices" display, but it would at least cause the reservation table to be in IP order for a little while.
Yes, you can edit the commands as you wish, everything should have been wiped after a factory reset. You can also use the telnet commands to change an existing setting, so if you enter the config command for the same variable twice like this:
config set reservation3="192.168.1.20 A0:99:9B:0B:3F:5B Dicks Macbook"
config set reservation3="192.168.1.20 A0:99:9B:0B:3F:5B The new Macbook"
Then the second command will override the first one.

Have you tried setting the orbi_dev_namexx and orbi_dev_name_ntgrxx entries through Telnet?(I'm not confident where I would click "apply" to have them take effect.)
Yes, I tried that, changing the device name by changing orbi_dev_namexx and orbi_dev_name_ntgrxx entries through Telnet does not need any apply. Once you send the config commands you will see the changes on the "Attached Devices"
Please note that there is another parameter in orbi_dev_name_ntgrxx parameter (orbi_dev_name_ntgrxx=24:92:0E:31:52:FA 14 Samsung Tablet) containing information about the device type as you can see in the following post:
Thanks for pointing that out. That's the index into the drop down menu of device types that (although an interesting concept) is worefully out of date. No entry for "Smart Plug", "Light Bulb", "Appliance" (like Microwave), Thermostat, etc.
Still gathering enthusiasm for a reset. I did a restart yesterday, and now my log file is reporting DHCP assignments again. Still no DoS and Port Scan reports.
Well, this is more of a challenge than I expected.
My "plan" was to have the reservations in order by IP address and matching the IP address, but I have left gaps in the IP range for future devices. (IP cameras start at 51, for example). Can there be gaps in the reservation table? Hmmm. My guess is "not". I have 26 devices in "reservations", but only 20 in "ntgr"
That "ntgr" looks like it is not tied to the drop down menu, but somehow keyed to the MAC manufacturer. I wonder if that will fill in automatically?
The device "name" table contains every device I have ever given a name to, even if I got rid of it months ago. If they truly get a new IP from DHCP every time they show up, the name follows them around.

No, I tried that and Orbi will ignore any variables that are not in serial, so you should have reservation1, reservation2, reservation3, reservation4, reservation5 then you can't have reservation7 without having reservation6

When you attach a device a random device type will be given by Orbi to the device. But if you have another device in your database with the same manufacturer as a new device that you attach (MAC address starts with the same digits) then Orbi will assume it's the same device type and will give it that device type.
In fact, there is also another list device_list1, device_list2, device_list3, ..... for OLD devices that you once changed the model or changed device type for that Orbi will also remember and use this database when setting the device types and model when attaching a new device to Orbi.

Exactly, once you give a device a name, model and type it will follow it once this device attaches to the system again. If you had a guest and assigned a name, model and a type to his/her device then Orbi will remember that when the guest comes back to visit you one year later when you check the "attached devices" menu.
