R7000P will not retain most configuration changes
I have a new R7000P which is newly set up and working. My existing network is in the subnet 192.168.8.0/24 and I have configured the router to have an IP address of 192.168.8.1
However, when I try to make any changes in Advanced > Setup > LAN Setup, the changes are not retained. I change the DHCP range to start at 192.168.8.10 and end at 192.168.8.200 (to avoid DHCP addresses being allocated that clash with my existing network devices) and when I save changes on the Netgear device, the web page states "Updating Settings", the device will restart, but the settings I have made are not retained and change back to the default DHCP range of 192.168.8.2 to 192.168.8.254
Also, when I try to change the ISP allocated DNS settings, these are not retained; in Advanced > Setup > Internet Setup, I change the DNS server from the ISP provided addresses to another DNS address (I am using 1.1.1.3 to provide DNS protection from Malware sites), the web page states "Updating Settings", the local network and WAN drop as the device is restarting, and then the changes I have made are not kept and the settings return to the ISP default IP address for DNS servers.
Worse of all, if I try to make a DHCP address reservation in Advanced > Setup > LAN Setup, if I select to add a reservation and choose an existing device on the network from the address reservation table, I get the error message "The IP Address should be with the DHCP range" - even though the address is definitely within the DHCP range (for example, I need to make a reservation for a printer at 192.168.8.7). This error message is given if I try to manually add the MAC address, or if I choose the device from the list. This has already been a problem when devices have been allocated DHCP addresses that conflict with other manually configured devices on the network (my PoE CCTV has stopped working due to an IP address conflict, and I have to power off the DHCP allocated device to get things working again).
There are other strange things happening that are more annoying than a problem; my timezone is GMT +9:30 (Adelaide/South Australia), and this is not listed on the NTP page. At random times when going through the Advanced settings, I am presented with the admin password forgotten page - asking for my serial number and to reset the password. I am able to bypass this by closing my browser.
My R7000P has firmware 1.3.1.64_10.1.36
How do I make my router save the settings I am making? Are previous versions of the firmware more reliable and consistent?
I finally resolved the problem.
I tried to change the LAN address of the Nighthawk R7000P from the address 192.168.8.1 to the default 192.168.1.1 (Advanced > Setup > LAN Setup) - but this setting change again would not be saved. I tried to change the Internet settings (Advanced > Setup > Internet Setup) to use the ISP provided DNS settings, and then I got the strange error "MAC address invalid format" - even though I was not changing the MAC address of the router, the MAC address was valid and in the correct format - a very strange error when trying to change the DNS settings to default/automatic.
So, I realised that something is really wrong - and I could not change the settings to fix it, so I had to do a factory reset.
After the factory reset, I again set the router's IP to be on my network (change to 192.168.8.1) and the same problem happened - could not change any settings after the IP was changed away from the default of 192.168.1.1
After a second factory reset of the R7000P, and completely re-addressing all my other equipment, including manual configuration of all my other devices that need to communicate with each other (which took around 5 hours), I have now moved everything to the 192.168.1.0/24 network and finally I am able to make configuration changes to the router, and it retains the settings!
Very strange - has anyone else had problems with changing to a network other than 192.168.1.x?

Why? Are you running some sort of exotic network that requires you to diverge from the usual?
People may need to know more about what is going on at your end before they can understand the issues and where the solutions might lie. The standard answers and troubleshooting suggestions might not work on unconventional networks.
It might also help if you told people what the modem is in front of this router. The model number could be useful. Is it, by any chance, also a router, with a set of LAN ports on the back?
The reason for asking is that a lot of people turn up here trying to put a router behind a modem that is also a router. That can complicate troubleshooting.- The subnet range should be irrelevant to my problem. I do not use the default 192.168.1.0/24 network for security reasons, and because I already have a number of devices using the 192.168.8.0 network. Making a change to the third octet is most certainly NOT "exotic"!
I have no router or modem. I am on fibre, so my 100 Mbps Internet connection is presented as Ethernet, no login required.

True.

As with most such misbehavior, a reasonable start would be a
settings reset and manual reconfiguration. You could try _not_ changing
the LAN subnet first, just to ensure that such a simple/harmless change
isn't beyond the capability of this thing.> Are previous versions of the firmware more reliable and consistent?
Not having touched an R7900P, I know nothing, but I'd consider
running the experiment.

If the thing really won't allow any address reservation, then it may
be too defective to be useful. I wouldn't trust/tolerate any gizmo
which wouldn't let me reserve a non-pool address (let alone none at
all).> [...] my timezone [...]
I dimly recall another similar-sounding timezone complaint here. A
forum search might find it.
