Still DHCP and Port Forwarding Issues
First let me say that I'm not interested in the pointless questions that end up being a stall tactic by support. Read my issue (it's one that most are familiar with if you've used this system for some time) and just admit that Netgear still hasn't solved the issue. Give specific workarounds instead of recommending a better CAT6 cable. I've been doing this for a long time and don't need frivolous suggestions that waste my time.
So I'm using the Nighthawk MR60 (61, 62?) mesh system with around 80 devices connected at any given time. I have multiple ports forwarded and static DHCP reservations. There are still DHCP table corruption issues that haven't been resolved since this product was released. When an IP reservation is edited, added, or deleted, the Port Forwarding table still goes invisible. You can't add or edit anything in Port Forwarding, because the router still has the values written even if they aren't being displayed.
Last night, I changed a single DHCP address reservation and the tables were immediately corrupted upon reboot. Latest firmware on both the router and satellite (only using 1). DHCP wasn't assigning IP's to non-appliance hardware like both Amazon and Apple devices. After a factory reset (didn't work) and then finally restoring from an old backup I had, I was able to finally get DHCP to assign addresses.
Netgear, what's the workaround for this years later? Recent firmware from November allowed more than 64 devices? Always did, so I'm not sure what's being fixed in these firmware updates (which can also cause DHCP table corruption). I'm going to hope that I can re-add port forwarding tonight without losing DHCP reservations as the two seem to have an effect on one another.

What Firmware version is currently loaded?
What is the Mfr and model# of the Internet Service Providers modem/ONT the NG router is connected too?What browser are you using? Happens in other browsers as well?
What is the default DHCP IP address range you using? Default .2 to .254? Would you try using .100 to .200 and let us know if anything changes?
uPnP is disabled as well?
Collecting data so I can pass this onto NG. Thank you.

Also will need more information on what your setting up for reservations and what and how your configuring Port Forwarding.
I tried a simple PF on my MR60 today using MS Edge. I have my two MS that already been reserved last time I had the system online and added 1 wired PC set for IP reservations.
Added a simple FTP PF preset rule to the Port Forward configuration.
Disabled uPnP.Made a change the host name of the PC that had a reservation, could still navigate and view the PF web page.
Changed the IP address reservation of the PC to a different address and applied the change, could still view the PF web page.
Seems like this maybe a user mis-configuration issue.
- Using DHCP reservation scope of 192.168.1.100-200
- Latest firmware on both router and satellite
- Over 75 devices connecting on both bands
- Port forwarding table will disappear when making changes to static DHCP assignments
- Attempting to re-add ports produces a duplicate assignment error
The only way to fix this is to restore an old backup that was stable, from an older version of firmware. At first, the new firmware wouldn't take the CFG file but still tries and apply it anyway. Another misleading error message.
Browser might play in this scenario, but I didn't see a difference. I'm on a Mac, so Safari and Chrome are it. It's a specific firmware problem that Netgear (and you) are aware of, but you aren't acknowleging the the firmware is buggy, at best, even with endless posts about the topic. I think you've collected as much data as you need.
