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.
