Hi Renato,
make sure that wifi is enabled and the required firmware is installed as
outlined in step 7 here:
https://hub.mender.io/t/how-to-configure-networking-using-systemd-in-yocto-project/1097
:
DISTRO_FEATURES:append = " wifi "
IMAGE_INSTALL:append = " linux-firmware-rpidistro-bcm43430 "
Greetz,
Josef
