i needed to find out that on antergos ( my laptop) the reg set preferences are set to us.
iw reg get
which leads to the problem that i cannot not connect to a certain wifi i would really need because it is running on channel 12 which is forbidden in US. so i cannot see the net and do not connect and do not have no internet.

with aricrack-ng suite i can see nthe net so my chip is defenitley capable of finding it.
i can also change the setting with iw reg set JP for example but then i still cannot find the net. also not after putting wifi down and up again…

so A i would like to change the setting on my pc

B it would be good if theres taken care of that while installation.
