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](https://forums.balena.io/t/disable-wifi-power-management-wireless-power-off/132105) 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 🙂

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](https://www.balena.io/docs/learn/more/masterclasses/host-os-masterclass/#52-making-networkmanager-logs-more-verbose-in-four-ways) logs. If you can share verbose logs, it would help immensely to figure what’s going on.

Thanks!
