I have had many unhappy experiences trying to use LuCI to change my configuration:
- Changing the LAN network rendered the box inaccessible
- Changing the wireless country code or the assigned channel made the corresponding radio unable to come up
In all cases I had to do a fresh install via the Foris wizard and hope that I got all of the setting right.
Am I doing something wrong? Where can I learn more about LuCI? Are there special protocols I need to follow when changing some settings?
