sorry, 19.07.2 tiny from current link on WHR-G300Nv2 page. Have not tried the other ones (unless you think it would work better).
Thanks for your feedback, I have updated the WHR-G300N v2 dataentry accordingly.
WHR-G300N v2 lose configuration after reboot. I am using the tiny build 19.07.3.

Hello.
I also have this problem with WR841ND v9 and 19.07.2 and .3.
Tried also clean install (clean firmware mtd1 partition, tftp 18.06, upgrade to 19.07).
EDIT: What I see the problem is mainly with the Tiny package for 4MB devices.
I just tried to install community build of 19.07.3 and it works OK.
So this is probably the way, as 4MB devices were deprecated...
Netgear "wnr2000 v3" is resetting to stock when rebooted.

That's with which 19.07.x relase exactly?
With 19.07.2.
I did a bit more research into the OpenWrt documentation, and figured out that my device is in the 4 Mb flash / 32 MB RAM category, and that was causing the issue. I build a custom image using imagebuilder, removing some packages and it works now, i.e. it saves config between reboots.

No, it's not. The tl-wdr3600 has 8 MB flash, which -while not plenty- is sufficient for modern OpenWrt, now and within the immediate future. Your paste shows that you have a 3.9 MB large overlay at your disposal, but at the same time you already filled up 3.6 MB of that, leaving you with only 244 KB 'free' space. With jffs2 needing at least 5 free erase and you being down to 4 and under, that is a problem - you need to reset (firstboot) your device to recovery and keep a closer eye on your flash usage in the future. But your device is not one with systemic flash shortage, as 4 MB flash devices would be. 8 MB isn't much, it needs some attention to keep it at bay, but it is workable.
There must be something wrong with the sysupgrade image. I literally just did a firstboot reset and the device is full and not saving settings between reboots.
I have the same device, no issue here.
Edimax 3G-6200n z OpenWrt 19.07.2 lost settings after reboot or turnoff. It doesn't create JFFS.
Steps:
- Download the latest version OpenWrt 19.07.2 to Edimax 3G-6200n.
- Set e.g. the password to the router and/or turn on the WiFi.
- Reboot the router with the reboot option in OpenWrt.
- The router has no settings previously saved - the status is as right after installing fresh OpenWRT - no password, no WiFi enabled, default settings.
Problem with JFFS.

Thanks for your feedback.
Can you determine which is the last working OpenWrt release that is working?

Yes, I can if it will be helpfull. I will find free time and check other versions of software for my Edimax.

@tmomas, I've checked many versions: 19.07.1, 19.07.0, 18.06.8, 18.06.7, 18.06.6, 18.06.0. In all these versions problem is as I wrote above.
Version 17.01.7 (lede-17.01.7-ramips-rt305x-3g-6200n-squashfs-sysupgrade.bin) works perfect and save settings after reboot.

Is it any chance to fix this?
I saved these logs from SSH console for all softs which I tested.
If you want more information tell me.

Unless you upgrade your flash to 8MB or more: No.
The easiest way to solve this problem: buy a device with sufficient resources (i.e. preferably 16MB flash) for current OpenWrt.
OK, I understand. This is not my main router but I was trying find where is problem and be sure that it's depends on software not hardware. So the problem is in hardware.
This device is very old so for me was suprise that I can flash 19.07.2, for example on newer TP-Link TL-MR3220 (v2) I can flash max 17.01.5. So I don't know why 19.07.2 exist for Edimax if it's not able to work on this hardware.
