Just starting with octopi, following official octopi instructions.
Bought a pi3A+,
Etched a 4Go micro sd card with the latest octopi distro (0.17.0)
Using a 5V bench power supply that delivers up to 10A.
I managed to connect once my pi to the wifi, configured it, but as soon as I reboot my pi, it won't connect to the wifi again.
Nothing helped me in the wifi troobleshooting FAQ.
