I am using Arduino Yun and I would like to disable it to work as Access Point. That is, I don't want that it is displayed in the list of available networks.
Then I would like to set and use it (separately) in the following scenarios:
a) Arduino Yun connected just over a given Wi-Fi network (Ethernet connection disabled).
b) Arduino Yun connected just over Ethernet (Wi-Fi connection disabled).
How can I make it?
Note: In my previous attempts I tried to customize and/or disable someway the Wi-Fi connection (through the LuCI panel) in order to reach what I am looking for but in all of these cases I had to restore my Arduino Yun from scratch because it did not work anymore.
