Kernel 5.3.0 does not have wifi drivers yet.

Maybe try kernel 4.19 official build from Khadas ? If your using external usb wifi then maybe there is no wifi support enabled in 5.3.0 by khadas for that chipset.

yes,
5.3 no wifi, no gpio
4.19 is ok

#4

If the image is assembled correctly, USB WiFi modules work without problems in kernel 5.x.
