That's a good idea. Developers can already see that from the "fwapi 4"
print but somekind of explanation in english should reduce the confusion
with normal users.

That's always a good idea, for example you could try just released v4.8.
Does ubuntu still provide .debs for upstream kernels?
Or you can try backports:

Then I suspect this is something else than board file related, but of
course I can't be 100% sure. You could also try enabling debug messages
and see if they reveal anything, for example debug_mask=0x00000432 is a
Have you verified that this is not a hardware problem? For example, does
the board work on Windows?
Also make sure that you have killed wpasupplicant, network-manager or
any other entity which might control the wireless device (very unlikely
that would cause this but better to be sure).
What channel is your AP in? Are there multiple APs in the area? This
could be also a channel problem, 'iw list' helps to investigate that (or
changing the channel on AP).
