How to disable DHCP on R7000P
I can uncheck the DHCP box on Advanced/Setup/LAN Setup but when I attempt to Apply the changed configuration, I get the error message "The IP address conflicts with the WAN IP subnet. Please enter a different IP address." I've changed nothing else on the page except deselecting Use Router as DHCP Server. Reloading the page shows that the DHCP Server is still selected.
How can I get past this this error message?
Wan is served by a cable modem which gives the router a Wan IP in the 66.51.xxx.xxx range.
My router is running the V1.3.1.64_10.1.36 firmware.
Success!
I'm on the latest firmware: V1.3.1.64_10.1.36
I did a hard reset and reconfigured the router. On the page Advanced/Setup/LAN Setup, I changed the router IP to 192.168.10.1 and hit Apply. Once the router rebooted, I changed the IP back tp 192.168.1.1, turned off the DHCP Server and hit Apply. Also turned on the DHCP Server on the Pi-Hole. This got everything working. Apparently the router wants to see a change in it's IP address when turning off the DHCP Server. I don't know why.

the LAN IP subnet. What do you see under ADVANCED > Setup > LAN Setup :
LAN TCP/IP Setup?What were you expecting to use as a DHCP server after disabling the
one on the R7000P? How is that one configured? Is it already active on
your LAN?If the router settings look reasonable, but the router complains in
unexpected ways, then I'd try a settings reset and manual configuration
of the router.> Wan is served by a cable modem [...]
Not a very detailed description of that device. Maker? Model? Is
it a modem or a modem+router?I've attached a small png showing the LAN TCP/IP Setup. It's in no way interfering with the WAN IP. From here, I hit Apply and the error message pops up. Reload the page and the DHCP Server shows as being selected again.
I'm running Pi-hole on a Raspberry Pi 4B on the internal network. It has a DHCP Server that is currently disabled. Once I get the router's DHCP server off, I can enable the Pi-hole's DHCP server with a mouse click. It's currently serving as the DNS server for the Lan with no problems.
I've been trying to get this going for a few days now. Tonight, before my first post, I hard reset the router and reinstalled the firmware with the Update utility. So there should be no leftover config. It didn't help.
Cable modem is a Arris Surfboard SB6141, pure modem, not a router.
Wan IP is 66.51.xxx.xxx and Lan IP is 192.168.1.1 (the default) so I really don't understand what's going on.
Thanks for your help!
Netgear does not really want to understand the need to run an internal (LAN side) DNS server - the Netgear consumer routers don't allow configuring LAN-side DNS servers e.g. a Pi-hole why ever. The issues here where the DHCP is forced enable looks like a bug to me. If the router would allow a proper DNS config, operating the DHCP on the router would not be the worst idea.
One issue more for ChristineT 's list of problems to report to the consumer BU management.
