    [R7800] Will no longer save settings after reboot.

    Yes, if the Macronix NAND flash chip is faulty/less robust/weak, etc., I suspect it is only a batch of them--not all of them. Indeed, since this occurs ACROSS product models (just inspect the 35+ threads on the Netgear forums for proof of this...), it would seem to point to a defective...

    [R7800] Will no longer save settings after reboot.

    Though there seem to be a recent flurry of reports on this issue, and at least in this forum that time frame can be related to a certain revision of Voxel's firmware because many folks are using it, I do not think that this is a firmware problem at all. The evidence is much stronger to suggest...

    [R7800] Will no longer save settings after reboot.

    Great, so you could basically have a spare USB drive dedicated to being a failsafe reset drive that removes the /nvram_backup files--so another step forward! Here is a fundamental question--when the early boot nvram restore happens, does it actually write the configuration to the mtd11, which...

    [R7800] Will no longer save settings after reboot.

    Yes, I installed the latest OpenWRT v19.07.2 using the TFTP flash method. You need a computer with an actual ethernet port--not just a wireless connection--but once you figure it out, it is very simple, and also failsafe. I am sorry to hear that your R7800 has failed in the same way as so many...

    [R7800] RAE, cloudfront ??? Netgear snitch?

    I think the "RA" in "RAE" stands for "router analytics". Search for "rae" on the OpenWRT page for the R7800, and you will see references to it in the OEM Bootlog section. That URL is: https://openwrt.org/toh/netgear/r7800 What it actually does is another question!

    [R7800] Will no longer save settings after reboot.

    Thank you @HELLO_wORLD and @kamoj!!! This is wonderful progress, and will undoubtedly be greatly appreciated by those whose R7800s are out of warranty, but suffering from this frustrating issue!

    [R7800] Will no longer save settings after reboot.

    So I have not actually attempted a full factory reset with the reset button on my R8700 with OpenWRT because it is still under heavy use for leisure activities at the moment. But there is a whole webpage on the OpenWRT website that discusses the various types of resets that one can do. For the...

    [R7800] Will no longer save settings after reboot.

    As @kokishin has said, completely understandable, and we are all in the same boat regarding the extra stress and responsibilities from work at home nowadays. So no problem at all, indeed, for those whose routers are afflicted with this issue, we would be thrilled that you would even consider it...

    [R7800] Will no longer save settings after reboot.

    Yes, it's a vicious cycle. I mentioned a while back that all the configuration settings that one sees in the web GUI are actually just implemented as text files under the filesystem. The web GUI just puts a pretty face on it. So this also provides a potential path to a solution. Imagine...

    [R7800] Will no longer save settings after reboot.

    A-ha, I was thinking about this, and had a response already started, but just pulled the trigger on it after returning here. I will investigate the reset button under OpenWRT this evening so as not to disturb the peace right now!

    [R7800] Will no longer save settings after reboot.

    Interesting thought! So the router would get into some type of perpertual reset mode, which if running official Netgear/Voxel firmware would trigger the erasure of the mtd11 partition. This brings up an interesting thought--what does the reset button do under OpenWRT, for example, since there...

    [R7800] Will no longer save settings after reboot.

    Interesting observation about the potential consequences of this. What would be ideal is the following. If these settings could be stored on an external USB drive, and the rootfs could potentially look there first before restoring settings from the local rootfs... In fact, a future pipe dream...

    [R7800] Will no longer save settings after reboot.

    @Redbot, this is a super-interesting observation that after your R8700 sat around for a week in a box, it seems to be working again and remembering settings. But I think you are right about not trusting it because I suspect the problem will return. So in your case and my case, leaving the...

    [R7800] Will no longer save settings after reboot.

    Thanks for the additional insight and details, @HELLO_wORLD. For sure, I understand this could be dangerous, i.e. that one could end up with a bricked router that would require a flash of the firmware using the tftp method vs. doing it by the normal web GUI method. So this would only be for...

    [R7800] Will no longer save settings after reboot.

    Wow, wow, wow--this is great news!!! For sure, I completely understand this depends on your time, the overall demand for a solution, and finally, on end users who can feed you information and try things out to debug it. Of course, I am willing to help with the latter.

    [R7800] Will no longer save settings after reboot.

    Oh, this is great! And if you and @kamoj can share the details, that would be cool! Regarding the file that holds a backup of the nvram from a previously saved state, is this specifically a configuration settings backup file that one might have produced through the web GUI previously (like...

    [R7800] Will no longer save settings after reboot.

    I agree with you about the R7800 still being very functional and useful--as I mentioned, I still love my R7800! It is fantastic except for the fact that it loses its settings, which is a major headache. At the beginning, I had no option for mitigation--but now I do with OpenWRT. Whether...

    [R7800] Will no longer save settings after reboot.

    Fair enough--this is probably a wise suggestion that may help avoid future problems. But let's not lose perspective here--there are many R7800s out there that have been running for years--through many flash cycles and undoubtedly a number a power aberrations, too--and they are still running...

    [R7800] Will no longer save settings after reboot.

    Hi @tommytqt, yeah, the heat issue has sort of fallen by the wayside over the last few days as discussion has shifted direction a bit, but like @HELLO_wORLD observed several pages of comments back, it may be that heat exacerbates the issue, but is not necessarily the main cause. For example, it...

    [R7800] Will no longer save settings after reboot.

    Interesting possibility--the A/C adapter for my current R7800 is indeed different than the one that came with my original R7800. So as I understand your suggestion, another potential interpretation is that--instead of a subtle change in the power circuitry--a change in the A/C adapter might...
