We haven't specifically tested the DAKboard OS on a Pi Zero, and generally don't recommend it due to it's limited CPU/RAM. However, one user did mention that for some reason, the Pi Zero takes a long time for the wifi to start up. Due to this, the OS assumes it's offline and starts the hotspot/setup mode. 


To get around this, try increasing the time in this file:


/etc/systemd/system/autohotspot.timer

Find the line that contains OnBootSec=30 and change that to OnBootSec=60 or higher if needed. 

Save your changes and restart the Pi. When it boots back up, it will wait the specified time before testing for connectivity.
