19.07 -- Report devices here that can't save settings

[yorksun]

I don't think the size is an issue for this device. However, the configuration gets lost after reboot.

WZR-HP-G300NH2

I tried 19.07.6 and found the settings survived reboot. So this is a different issue I guess.

Do you also want to have devices reported here that experience OOM issues after an upgrade?

the following device has issues with 32MB RAM, according to the user first experienced with 19.07:

Kernel errors (ath: skbuff alloc of size 1926 failed ) (32 MB RAM device)

Hello Team, Since I upgraded to OpenWRT 19.07.7 I have been observing the following errors in the kernel log. [1058685.313637] [1058685.315351] ath: skbuff alloc of size 1926 failed [1058685.320260] hostapd: page allocation failure: order:0, mode:0x1080020(GFP_ATOMIC), nodemask=(null) [1058685.329436] CPU: 0 PID: 1440 Comm: hostapd Not tainted 4.14.221 #0 [1058685.335801] Stack : 819a6080 800b2d94 80500000 804b2a28 00000000 00000000 00000000 00000000 [1058685.344376] 00000000 00000000…

for me, finding devices tagged as being regularly supporting by 19.07 and then finding the same devices with OOM issues in forum threads seems a bit weird.

[slh]

No, this thread is (was, with 21.02 these devices aren't built anyways) about devices with insufficient amounts of flash for the default firmware. 32 MB RAM is already documented explicitly and expected behaviour (it might still boot with reduced features, but that's another topic).

Edimax 3G-6200n z OpenWrt 19.07.2 lost settings after reboot or turnoff. It doesn't create JFFS.

I see that for Edimax 3g-6200n we can check new version of OpenWrt and confirm that the problem still exist or is resolved:

• 19.07.4 (r11208-ce6496d796)
• 19.07.5 (r11257-5090152ae3)
• 19.07.6 (r11278-8055e38794)
• 19.07.7 (r11306-c4a6851c72)
• 19.07.8 (r11364-ef56c85848)
• 19.07.9 (r11405-2a3558b0de)
• 19.07.10 (r11427-9ce6aa9d8d)

Unfortunately my Edimax 6200n stopped working (in normal use). I will try to fix it or maybe get a new device. Or maybe someone can verify if the problem still exists on this Edimax model?

@olekstomek

Unfortunately my Edimax 6200n stopped working (in normal use). I will try to fix it or maybe get a new device.

I checked on other Edimax 6200n equipment that I managed to get. Overall the same problem.

On 19.07.4 version I set the password and turned on WiFi, on the next higher versions and 19.07.3 I only set the password for the router. Settings are always lost after restarting the router with LuCI network. I updated the software without keeping the settings from the previous version. Logs are added in order of update. In the logs you can see e.g. differences in the amount of memory depending on the version (they are small). Below are logs for commands

mount
df -h
free

on individual versions of OpenWrt. I executed the commands after setting the password and rebooting.

Here, see that I go back to an older version from 19.07.9 to 19.07.3. Version 19.07.3 was not in firmware selector and I found the bin file with the firmware manually (https://downloads.openwrt.org/releases/17.01.3/targets/ramips/rt305x/).

As 19.07.x is EOL, there won't be any changes/ fixes anymore - not that there would be a fix to these size issues to begin with (other than disabling the affected devices from being built).

OpenWrt 19.07.10 service release

Hi, The OpenWrt community is proud to announce the newest service release of OpenWrt 19.07. It fixes security issues, improves device support, and brings a few bug fixes. OpenWrt 19.07.10 is the final release of the 19.07 release branch, this branch is now end of life and we will not fix problems on this branch any more, not even severe security problems. We encourage all users still using OpenWrt 19.07 to upgrade to OpenWrt 21.02 or more recent OpenWrt versions. Download firmware i…

(Marking this thread as solved, as there is nothing to 'fix' anymore - 19.07.x is EOL, 21.02.x+ doesn't support 4 MB flash devices anyways, considering average firmware sizes just shy of 6 MB)
