Octopi connecting just once to wifi

Question

Just starting with octoprint.

• 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.

• Following official octopi instructions

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.

Any hints?

Nothing helped me in the wifi troobleshooting FAQ.

I thought that I changed a particular config but :

• without configuration change, I:
  • started the pi once
  • waited until the pi connects to the wifi
  • successfully pinged the pi via my PC
  • rebooted the pi
  • a new ping wouldn't work
• I compared the files on the boot partition and only this changed:
  • freshly etched sd card:
    • cmdline.txt:
    • console=serial0,115200 console=tty1 root=PARTUUID=6c586e13-02 rootfstype=ext4 elevator=deadline fsck.repair=yes rootwait quiet init=/usr/lib/raspi-config/init_resize.sh
  • card from rebooted device:
    • cmdline.txt:
    • console=serial0,115200 console=tty1 root=PARTUUID=6c586e13-02 rootfstype=ext4 elevator=deadline fsck.repair=yes rootwait

there is no more differences.

Answer 1

What worked for me:

• changed SD card from 2 GB to 16 GB (do not need so much)
• power the pi with 5.4 V instead of 5 - 5.1 V
