Odd problems with an R7000
I've found a few problems. On the V1.0.9.12_1.2.23 right now, and was on it when I discovered a 'problem'. I backtracked to V1.0.9.10 and discovered another problem.
The 'new' problem is that I can NOT reset the R7000? At least I don't think I am (while on both of the above releases). I did the usual 30-30-30 deal. Router reboots with ALL settings intact? I recall in the past when I did this the base version installed when doing the 30-30-30 booted but with NO settings? I did have an older problem (https://community.netgear.com/t5/Nighthawk-WiFi-Routers/R7000-Reset-button-doesn-t/td-p/1037598) I posted here with a similar problem, but I am using a paper clip? Could the button not be working? I do see flashing lights so something is happening (maybe just a plain old reboot?)? Could the V1.0.9x firmware not allow a reset?
The other problem, a clear mismatch between the R7000 and Win10 what they think the IP Address Lease time is.
The R7000 from the ADVANCED page CONNECTION STATUS:
| Lease Obtained | 0 days,1 Hours,40 Minutes |
| Lease Expires | 0 days,0 Hours,30 Minutes |
Win10's IPCONFIG for the lease time:
Lease Obtained. . . . . . . . . . : Tuesday, November 28, 2017 3:51:34 PM
Lease Expires . . . . . . . . . . : Wednesday, November 29, 2017 3:51:27 PM
The difference seems to be causing the R7000 to ask for a renew of the IP Address and a Time Synch about a little over 1 hour all day long. This seems to possibly cause some delays in our Internet usage when it happens?
IF YOU HAVE AN R7000 ON THE SAME FLASH COULD YOU PLEASE CHECK THESE TWO ITEMS???
JamesGL, I finally got the ISP to see it was somewhere on their side. Had to remove the router and use just the modem and the problem was still there. Lease time only 2 hours or less.
On a related note I see the latest flash has a fix for when it renews a lease.
- Fixes the issue where Internet sessions are disconnected when the DHCP lease update occurs on the Internet port.
It was probably that that made me notice I had a problem since it was happening every hour or so and sometimes browsing hung for a short period or reported a connection was broken?

Well, solved the RESET problem basically. I used the ADVANCED function BACKUP SETTINGS to ERASE the settings and revert to factory defaults. Worked, when I tried to access the router it worked like it was a new router. Asked for all data to be entered via Genie, even register the router. Checked and everything was cleared and set to a default. Could it be that is the only way to reset a router now? Button did NOT work?
That was the GOOD news. Bad news, the IP ADDRESS lease time is still less than 2 hours...
If you are READING this, have an R7000, please check your LEASE TIMES on the ADVANCED TAB under INTERNET PORT and select CONNECTION STATUS. Please REPLY here, no matter what you see? As I understand this the ISP sets it (it is the server) and the router is the client and asks for it, usually 1/2 the time the lease is set for. The router doesn't set the lease duration, the ISP does. If you've got similar results to what I'm seeing, and I am correct as to who sets the lease duration, there is a problem within the flash for the R7000. However W10 gets the lease details it always shows a 24 hour lease vs. the R7000 showing 2 hours or less.
JamesGL, ElaineM, ChristineT, can ANYONE from Netgear comment on this?

Are you comparing the router's WAN/Internet interface with the
Windows-system network interface? Why should they be similar? The
router's WAN interface gets its data, including the public IP address,
from the ISP DHCP server. The Windows system gets its data from the
router's (LAN) DHCP server, which is entirely independent from the ISP.
The addresses differ, the subnets differ, the DHCP servers differ.
Why should the lease times match?

Why should the lease times match?Yes, I agree with where each gets the Lease info.
The question is why are they different?
Again, which is what I'm having a problem with, what is shown on the Router in the Advanced tab's Connection Status? For instance,
Lease Obtained 0 days,1 Hours,57 Minutes Lease Expires 0 days,1 Hours,2 Minutes Did that not come from the ISP as you say? If not, why is the router placing various times (usually less than 2 hours and more than 1 hour) on the lease length? My ISP claims that this is NOT their problem. They have (and always have had) 24 hour leases. So if the ISP has a 24 hour lease period, why does the R7000 think it is less than 2 hours?
So you say " The Windows system gets its data from the router's (LAN) DHCP server, which is entirely independent from the ISP." OK, but if that is the case, then if the Router shows me a lease period of less than 2 hours, wouldn't W10's IPCONFIG show the same matching info? It doesn't:
Lease Obtained. . . . . . . . . . : Wednesday, November 29, 2017 9:10:26 AM
Lease Expires . . . . . . . . . . : Thursday, November 30, 2017 9:10:25 AMThe two just don't match? As I see it, the client is the router and the server is the DHCP server on my ISP's network. So the Router should be doing what it is doing, but the question is WHY is the Router showing a lease period of less than 2 hours? So again, if you are right above, the router's (LAN) DHCP server KNOWS it has a 24 hour lease? Why then does it think it has a less than 2 hours lease and asked for a RENEW every 1 1/2 hours or so? Would this NOT be a bug in the Firmware?
Other possibility, my Router is 'bad' and processing the data wrong.
Do you have an R7000? What does your data look like?
> The question is why are they different?
That may be _your_ question. My question is: Why should the lease
times match?
The router's WAN interface talks to your ISP, or at least to some
other gizmo which talks to your ISP. The properties of that connection
are negotiated between the router and the upstream DHCP server (at the
ISP, or other intermediate gizmo).
The Windows system network interface talks to your router. The
properties of that connection are negotiated between the Windows system
and the DHCP server in your router.
The two DHCP servers have no direct communication with each other. I
see no reason to expect the lease-time parameters of these two
independent DHCP servers, dealing with two independent sub-networks, to
be correlated in any way.
Netgear R7000 firmware offers no convenient user-interface method to
change the parameters of its DHCP server, so there's not much which you
can (easily) do to adjust them. The upstream DHCP server (at the ISP or
other intermediate gizmo) may also be beyond your control (depending on
what any intermediate gizmo might be).

Why should it? You're looking at two different interfaces on two
different systems, dealing with two different DHCP servers. The WAN
interface on the router deals with one DHCP server. The Windows
system's network interface deals with another (the router's) DHCP
server.
> The two just don't match?
Why should they? Everything about them is different.

That's an argument between you and your ISP (or other intermediate
gizmo). I have no knowledge of or control over that DHCP server.

The router's DHCP server "has" no lease on anything. A network
_interface_ can have a lease on an IP address. The router's WAN
interface gets an address from an upstream DHCP server, and there's some
lease-time associated with that reservation.
The Windows system network interface gets an address from the
router's DHCP server, and there's some lease-time associated with that
reservation, normally determined by the router's DHCP server. The
Windows system deals exclusively with the router's DHCP server; it has
no dealings with any other upstream DHCP server. The router's DHCP
server deals with its clients; it has no dealings with any other
upstream DHCP server.
> Do you have an R7000? What does your data look like?
Not at the moment; only a D7000. My "Connection Status" pop-up shows
nothing about the WAN DHCP parameters.
If it's not too much of an intrusion, why do you care about the
lease-time of any of these DHCP address reservations?
