Good to know that if i set it to 1 day or less, I will not loose connection in rebooting process, and I keep the same IP, even if I stay connected longer then the lease time. On printer static IP address example, you say the pool is from.

Should it be between these to number? Just starting to learn about network. You need to give your printer an IP Address outside the pool that you created. The pool is used to dynamically assign an IP Address to a random client. So fixed IP Addresses should be outside the pool, otherwise, the same IP Address can be used twice which will cause a conflict in your network.

So, make the necessary conversions to get the value in hours or minutes, depending on your preference. Immediately, the new DHCP lease time will be applied to the devices connected to it.

Go to Command Prompt and check if the new value is applied. For some reason, if you still find the old DHCP lease time values on your device, make a forced change.

The first command releases the resources, while the second command establishes a new connection with the new DHCP lease time. One thing to watch out for is IP address conflicts, which is essentially a mismatch between the settings on your router and device. If this is a persistent problem, consider moving to static IP addresses.

Once the DHCP lease value has been changed, the new lease time will be issued to your devices accordingly. This will allow any changes to your DHCP lease information to be applied immediately.
