I followed the instructions here to use my own SSL certificates for HTTPS to my router. As mentioned in the last line: I made sure the "Regenerate" box was UNCHECKED and that the "Save in NVRAM" was CHECKED. But a simple reboot of the router cleared my certificate and I had to do evrything all over again. Which feels pointless because I can't be bothered to these steps every time I decide or need to reboot my router for whatever reason. Am I doing something wrong or is there a better way to persist these changes after reboots?
