It would be nice to have the different usecases / configs explained side by side, this is more something for the OpenWrt Wiki.
For the AR-150 it would make a lot of sense to have 3 config directories onder the GPIO 7 and 8 switch. And several configs to choose from in the Luci menu
Router, AccessPoint, Hotspot, NAS, Sambaserver, Printserver, etc. /config a default failsafe config that can’t be changed from the GUI, and 2 ‘user configs’ under GPIO 7 and 8.
This way we could contribute our use case configs and share them here, and make the AR-150 ever more interesting.
