Increase DHCP LeaseTime setting?
Hi, Where can I find this setting to increase DHCP Leasetime? This simple setting it seems its not include in the firmware? Why is that? This is a basic setting that should in the firmware.
Not supported yet by stock firmware. NG has been asked years ago to add it but still no progress.
Why do you want to increase it? The default of 1 day is more than enough for home networks.

Curious what you expect to happen after this one day or 1440 minutes expiration time? I expect the DHCP client will retain it's assigned IP address forever.
When the lease reaches 50% (T1) of its validity period, the DHCP client unicasts a DHCP Request message to the DHCP server to request lease renewal. If the server renews the lease (counted from 0), it sends a DHCP Ack message to the client.
So after 12 hours, the DHCP server gives an ack an does start another period, reset the timer. This can continue for days, weeks, months.

Some people like a very short least time, like 2 hours or so, in places where lots of clients come and go so that the DHCP pool doesn't get exhausted that easy. Of course there are ways around that, but just saying. I don't know why you'd want to increase the lease beyond a day time.

Yes, this is a very valid reason! But not what was requested here in the subject.
