RS700 IPv4 Lease Not Renewing (still not fixed).
I have a Nighthawk RS700 currently running firmware 1.0.9.16. There is a problem with renewing the IPv4 lease. If I restart the router it picks up an Ipv4 address with a 24 hour lease. After 12 hours it should release and then renew that lease for another 12 hours. However, instead of doing this, it retains this lease for the full 24 hours, at which time it does, then release and renew the lease and this is where the problem happens.
When it renews the lease, it shows the Lease Obtained as 1 Days, 0 Hours 0 Minutes and below that it shows Lease Expires as 49710 Days, 6 hours, 27 Minutes (first picture). Some hours later all IPv4 traffic stops (second picture).
All the lights on the router remain white and the Ipv4 Lease Expires display continues to count down, but most websites can no longer be reached. The only websites that continue to work are those with an IPv6 address, such as Google, Amazon etc. Sometimes it is possible to renew the lease by using the Release and Renew buttons, sometimes you cannot log into the router at all, and the only option is a hard reset.
Exactly the same problem is exhibited with firmware 1.0.9.6, however downgrading to firmware 1.0.7.96 makes problem go away and the router renews the IPv4 lease every 12 hours, as expected. The thing is I really would like to continue being able to upgrade to the latest firmware as we are all waiting for the big one that enables MLO.
Further information.
I have a Nighthawk RS200 running firmware 1.0.5.22 that does not exhibit this problem.
I also have a Nighthawk AX6000 that, also does not have this problem.
My ISP is Community Fibre in London, UK.
I have a fibre to the premises connection.
My ONT is a Adtrans SDX621i connected to the router with a CAT8 cable.
As I bought the router second hand and it had already been registered, I do not qualify for the 90 day free support from Netgear.

Any help would be greatly appreciated.

Does the ISP required any special WAN connect configurations like PPPoE or is the connection all DHCP?
What CAT# LAN cable is in between the ONT and RS router? CAT6A STP is recommended.
Is Protection Engine enabled on the RS router?
Is IPv6 enabled on the RS router?
Have you tried a Non managed LAN switch in between the ONT and RS router? Seen it where some handshaking between a ONT and router can be resolved with a lan switch in the middle.
Thanks for very much your response. My answers in italics

No, no special connection just plain old DHCP and both my RS200 and AX6000 work fine.

Cat8
Is Protection Engine enabled on the RS router?
Yes
Is IPv6 enabled on the RS router?
Yes, and it works fine. It continues to work even when IPv4 drops.

Unlikely, to be the problem as this only started with firmware update 1.0.9.6 and can fixed by downgrading to version 1.0.7.96 but, I'll give it a try.
Is the CAT8 UTP or STP? STP is preferred.
Please disable Protection Engine on the RS router.
Hi LaddieParker ,
Please try the latest firmware release v1.0.9.16 (https://kb.netgear.com/000070321/), it addresses the DHCP issues introduced by FW v1.0.9.6.
I am already running firmware version 1.0.9.16 and I am still experiencing the problem, so it would seem that the fix that it includes doesn't fix all of the DHCP issues.
