Hello.
I know that this is a cheap board and probably no one want to waste
time with this "low quality" stuff.
However Fedora boot without any issue.
My question is: what about on board wifi? Is it better to go for an
USB wifi adapter?

Thanks,
A.

It's actually nothing to do with the quality of the device itself,
it's to do with the fact that the driver for the WiFi driver [1] isn't
upstream in the mainline Linus kernel, we don't typically pull in
drivers that aren't upstream, or at the very least been reviewed and
accepted for upstream, simply because it's a support nightmare and we
don't have enough resources to be able to do that.

Yes. I see.

I know and I understad this very well. In fact thank you for all your
efforts.

Another question related to dtb and dts.
Let's suppose I was able to compile such module (driver).
What about dtb? Are dtb files "distribution agnostic"? Or the related dts
file should be compiled along the kernel in use? I mean: can I grab a dtb
file from another distribution and put it on Fedora? (Yeah! I want to build
Frankenstein :-))

Thanks
A.

It depends. DT files are completely distro agnostic, in theory they're
OS agnostic, but it depends on the kernel used in the other distro, eg
if it was from a 4.14.x stable release it would likely work just fine
with Fedora and 4.16, if it was from a vendor tree based on 3.4 kernel
(at a random guess) it might work but probably won't, or you'll get
less functionality than just missing WiFi.
