RaspberryPi WiFi power management

Hi everyone,
I’m having a problem with WiFi on both the Raspberry Pi Zero W as well as the Raspberry Pi 4. On Friday I ran both devices to register the data I need, and today, i.e. Monday, I set up a hotspot to which the devices should connect. I checked the router’s dashboard and neither device connected. Only a reboot of the devices helped and then both connected without problems. I think it may have something to do with WiFi power management, although according to this forum thread that option should be natively disabled. Do you perhaps have any idea why this is happening? I’ll point out right away that now the reboot was possible, but I plan to place the devices in places where I’d like to just drive up in my car and know that the device will connect to the hotspot.
Raspberry Pi Zero W - balenaOS 6.0.50+rev1
Raspberry Pi 4 - balenaOS 6.0.50+rev2
Thanks for any help :slight_smile:

Hello @grzegmar96

Some ideas to test first:

  • Can you enable persistent logging on the devices, so that you can access the logs later, and across boots.
  • do you see anything suspicious under dmesg -wH
  • Also take a look at our HostOS masterclass, and especially the section on NetworkManager logs. If you can share verbose logs, it would help immensely to figure what’s going on.

Thanks!
