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

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