i just got two hap ac lite and both of them have the same problem.
when i save a file (config) it shows in the file list, but... when i reboot the hap ac lite all the files are gone.
There is more then enough memory free 10.6 mb used out of 16 mb used.
My rb2011 can save a lof of files, and it always work.
Watt am i missing?
