I am using dietpi with a RaspberryPi Zero and as such don’t have an Ethernet connection.
The only way I can access it is via ssh or by mounting the SDCard.
Things work OK when I am in my house, but when I go elsewhere I can’t access it unless I take out the SDCard and modify /boot/dietpi.txt with the new SSID and password.
How do I configure it to store 3 or 4 common wifi connections?
