"DNS" and "DHCP" are spelled differently for a reason. Is there some
actual problem which you are trying to solve?

Could be a firmware defect, but it might help to know what you're
trying to do, and why. If, for example, you had configured the thing as
a wireless access point, then some of these settings wouldn't matter,
whatever you did with them.
I apologize for the "DNS" brain fart. I meant DHCP. Let me explain what I'm trying to do.
I'm trying to connect an old router to my main router, an R6120 to use as a separate network for my smart home devices. I wire direct to a laptop and enter the setup. The first step, which I didn't mention the first time, is I'm trying to change the ip and and then disable DHCP on the old router. I've done both at the same time and both separately. The changes just don't take. Example:
Change IP from the stock 192.168.1.1 to 192.168.1.2.
Unheck DHCP server.
I hit apply and it goes through it's reboot or whatever it does.
It always comes back up with the factory IP no changes to DHCP.
The first thing I did was update to the latest firmware and I'm begining to think that was a mistake. I dug through my garage and found an old WPN824v2 and was able to change the ip on it, UNTIL I updated the firmware on it! Now it won't accept those changes either.
Both routers will still accept login password changes as well as SSID and wireless pwd changes.
Sounds like firmware but ???? I tried rolling back the firmware on the WPN824, but maybe I didn't go back far enough.
I realize that I'm now talking about 2 different routers, but it seems like the same problem. We can just concentrate on the WNR3500 if you'd like.

"wire" _what_ "direct to a laptop and enter the setup" of _what_?
(Hint: If a device has different types of ports, then "connected to
device" is not enough detail.)> Change IP from the stock 192.168.1.1 to 192.168.1.2.
And is the computer from which you're doing this already occupying
"192.168.1.2"? There are limits to just how whimsical you can get when
assigning IP addresses to devices.Let's forget, for a moment, what you've done, and consider what you
might want to do.
If you configure some old router as a wireless access point, which
would involve disabling its DHCP server, and attach it to your
main-router LAN, then you'd still have one big LAN, and all your devices
could talk to each other. So, nothing very "separate" about the devices
which are connected to the old_router-as-WAP.If you configure some old router as a full-function router, and
attach it to your main-router LAN, _and_ disable its DHCP server, then
there would be no DHCP server on the ("separate") old-router LAN, which
I'd expect to cause problems for typical devices.According to its User Manual, the WNR3500Lv2 is old enough that it
lacks a convenient WAP mode option. If you want to configure it as a
WAP, then you might see, for example:https://community.netgear.com/t5/x/x/m-p/1463500
That's written for a Netgear C6300-as-WAP, but the steps are about the
same for any other router (any make/model) which lacks a one-step WAP
option. If the router which you're reconfiguring has a WAN/Internet
Ethernet port (unlike a Cxxxx), then leave it unconnected.> [...] old WPN824v2 and was able to change the ip on it, UNTIL I

or what the new firmware is. But I wouldn't expect it to matter very
much.
