Hello, the problem is that the wlan0 interface is disabled on our units in U-Boot by default. Those are steps to enable and configure the Wi-Fi interface:
Set up the Wi-Fi parameters:
sudo nano /etc/wpa_supplicant/wpa_supplicant-wlan0.conf
Enable wlan0 in U-Boot
cd /etc/bootcmd.d/
sudo make enable-wifi
Set up management (DHCP) on wlan0:
sudo cp /etc/systemd/network/examples/10-wlan0.network.example /etc/systemd/network/10-wlan0.network
A reboot is required to reflect the changes in U-Boot:
sudo reboot
