I have a few Zyxel NBG-419n's that I use to increase the WiFi coverage on my property as they were free (given out by the phone company when they upgraded users). I use a WRT1900ACS as my main router.
I decided to upgrade one of them from OpenWRT CC to the current LEDE 17.x release. Installed with no issues.
Upon loading I am having an issue where my settings are not saved upon reboot, even a simple setting of the root password. From what I had figured out in researching things it sounds like it is touch and go with the 4mb devices having enough space to save settings (something with the overlay partition/mount being in ram). I also tried a newer LEDE 18.x snapshot and the settings are not saved.
Is this a known issue with 4mb devices or should this be working?
I will be posting a bit more information tonight when I have access to the router again. Anything besides df -h that would be useful?
