Why is there no DHCP Lease settings on a $200+ top tear router?
I need a Router with a DHCP Less time setting, I'm going to have to sell my R7000 or custom flash it becase a DHCP Lease time of 24hrs is a Very very short sighted setting. This setting causes 10's o...
The wheels on the Bus go round and round.................
Having more control is usually a good thing but the reasons given so far for the ability to change the lease time don't look very compelling.
A really long lease time of 10 days is potentially going to cause DHCP address pool exhaustion in an environment where a lot of unique devices come and go. Think guests with smartphones. Maybe OP's environment(s) don't have this risk but it still seems ill-advised to increase the lease time for all devices for the sake of a printer.
The lease is still going to be lost on the 11th day. The printer that was shut off for 4 weeks is still hosed.
The lease is going to be lost whenever the router is rebooted.
Netgear routers have a limit of 32 clients per Wi-Fi band. Too many long-lived leases may result in hitting this limit.
A static IP address or DHCP address reservation is a much better solution than globally increasing the lease time for all devices. It's a point solution to a point problem. Also, I'm skeptical of the argument that 99% of the people don't know how to use them. By this same argument, people won't know how to set a DHCP lease time.
Finally, people really should not be accessing printers by a fixed IP address. Network printers almost universally support Windows Printer Sharing and are, therefore, accessible by name. Many also are reachable through their mDNS (called Bonjour by Apple) name. Windows, OSX, iOS, Android and Linux can access printers by their Windows name.
I often use ip addresses for id. purposes. When I look at the address I know what the device is, like Canon printer, Brother printer or ip camera, NAS, etc. What is wrong with that when you say "shouldn't use assigned ip address"?

There is nothing wrong, per se. Humans are just better at remembering names than numbers. It's one of the reasons why DNS exists. It's easier to remember community.netgear.com versus 208.74.205.20 (yes, this is this forum's real IP address) or ipv6.google.com versus 2607:f8b0:4005:806::200e. Wouldn't you prefer to refer to your devices by name (e.g. "Canon", "Brother", "KitchenCam", "NAS")?
The other benefit of using a name is that the address can change and it wouldn't matter. Computers can handle it transparently, unless you go out of your way to hard code addresses.
Sure, it's not that hard to remember a few IPv4 addresses that differ only in the last quad. What are you going to do when IPv6 becomes mainstream and we rid ourselves of NAT? Although DHCPv6 exists, it's more common for devices to autocalculate their own address based on their MAC address. You're better off by not clinging onto IPv4 addresses as a crutch.
