FS#3298 - Edimax 3G-6200n z OpenWrt 19.07.2 lost settings after reboot or turnoff. It don't create JFFS #8165
Comments
xaibempp: Is there a reason why you dont use the latest openwrt version? Since May2020 there is the 19.07.3 release. Your issue report is from Aug2020. Does 19.07.3 work? Does the 18.06.8 work without issues? |
olekstomek: There is no version 19.07.3 or 19.07.4 (newest today) for my device. Look here - https://openwrt.org/toh/hwdata/edimax/edimax_3g-6200n, Supported Current Rel: 19.07.2 I haven't used version 18.06.8. For now I am focusing on the latest version but if necessary I will use 18.06.8. But let's try to clarify the situation with the latest firmware version. |
olekstomek: 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.
This part of the story can also be useful: https://forum.openwrt.org/t/19-07-report-devices-here-that-cant-save-settings/48046/40?u=olekstomek |
This is the problem that I reported.
I see that for Edimax 3g-6200n we can check new version of OpenWrt and confirm that the problem still exist or is resolved:
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? I asked here also. |
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
on individual versions of OpenWrt. I executed the commands after setting the password and rebooting. Powered by LuCI openwrt-19.07 branch (git-20.247.75781-0d0ab01) / OpenWrt 19.07.4 r11208-ce6496d796

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/).
