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.
Okay,
I want to de-crease the DHCP Lease time because of the guest network I want a shorter lease time periode of 8Hours.
That's why. So don't discuss with me ''Thats not need it, Etc. Etc. ''
This is a option what I want for guest network a shorter lease time periode.
So why is this basic-option not availble for us? While other brands have this option. I was on different brands have this option.
So tell me now how to achieve this?
As I mentioned in my very first post, there is no option to control the lease time. It has been requested long ago but NG appears not to be willing to add it.
Also, in your OP post, you want to increase the lease time but now you want to decrease it. Which one is it?

- I see.
Never know that this a thing on Netgear products.
It doesn't matter which I want, the only thing I want is the control over it. In my guest network I want to de-crease the DHCP lease time and in my other router I want to increase the lease time.
So again it doesn't matter which one I suggest, I need both to increase and to de-crease it in the other product...
I was hoping that this was a bug or a feature that was forgotten, but now I read more that Netgear is not giving the control to their customers. - Well, on the R7800 you can install Voxel's firmware and enable SSH. Then you can adjust the lease time in some file (no idea which one). That's the only way to do it. On the R7000, you can try enabling Telnet access in debug.htm (if they haven't removed it)
One could try OpenWRT or DD-WRT FW and see if there is a least time UI option with in those FW variants for the R7000. Those FWs have more granular advanced UIs than NG has. Those would be more up to date as the R7000 is getting up in age and highly doubt if NG will be spending any money to add features in just for one user. I believe the R7000 is already headed towards EoL from NGs side.
Lets keep it simple: The R7000 is a consumer router, supporting one LAN, one IP subnet, and one DHCP server. The Guest network is just a L2 isolated network.
Just to avoid some misunderstandings here: The DHCP expiration time is in no aspect a control limiting the possible connection or association time. The only reason for a shorter expiration time is to free-up no longer active DHCP associations, because of the device is no longer connected to the network.
Already explained, an active DHCP client device connection is refreshed repeatedly, the address reservation will be refreshed again and again (as defined by the T1, T2, T3) - it will remain active forever ... until its no longer required.

Curiouser and curiouser.
Not sure if I follow, but there's only one DHCP server for both your own LAN the the Guest one. So you can't keep the lease time for your LAN but modify the one for the Guest. If you set your own lease value, it will be for both your LAN and the Guest. The Guest is not an entirely seperate network with its own DHCP. It's mostly made of iptables rules and virtual interfaces.

The imagination on these moving targets is on us ... I -guess- there are two routers in place, each to cover a dedicated [W]LAN and the guest [W]LAN.
Decreasing the DHCP lease time in an environment with a big number of clients to prevent shortages on the DHCP pool is one thing.
The "why" increase the lease time is more a "because I want to configure what I want and Netgear does not allow".
Equally, no response on the "How is the DNS problem drops being in this release?" also brought on the table, but at least denied later on.
I'm not even convinced the OP did understood why we had some questions before. Wonder what new moving targets will arrive to this discussion soon.
Reminds me to the request for longer DHCP expiration times (on some systems defaulting to 8 hours) "because we are often gaming in sessions longer than eight hours and don't want to be disconnected" we've seen before. Exactly this does not happen! But this is why we're asking ugly questions 8-)
Happy New Year and Peace to everyone!

Does the "guest" network follow the same rules as all the others?
I would ask Hot54321 why they wanted to change the Lease Time for that, but they don't seem to want to tell us why they want to tweak this setting.
First of all,
I have already told that I want to increase and de-crease on 2 seperate networks in 2 different envirement I want change the DHCP lease on the guest network from 24Hour to 1Hour because people come in and out.
So having this control gives me more flexibility to work with.Second,
"How is the DNS problem drops being in this release?" This question is being asked about the product R7800, not for the R7000. in the early versions/firmwares of the R7800 there was a problem occurred when with DNS drops for the model R7800.
I don't have this problem, but I was wondering how the latest firmware behaves about this problem what was before.

Saying it again, I don't have these DNS problems. Maybe I posted in the wrong post. But what I want is to have control over my DHCP lease time. For me, it's ''new'' that Netgear Products never had this option flex. for the customer...
If I had known this before I never have bought a Netgear product in the first place.Thank you with thinking with me.
I'll will look into the SSH with a Voxel's firmware to achieve changing the DHCP lease.

How many guests do you have on your network on the guest environment in one hour, and in one day?
Still unanswered is the question why you intend to increase the DHCP expiration time on the other environment.
