Linux 5GHz access point REGULATORY DOMAIN problem (debian+ hostpad + dnsmasq)

I am getting problems setting a 5GHz access point with a lattepanda 3d. I run the following setup: - Debian - Hostapd - Dnsmasq - iw (for set/get reg dom) In the end I am able to successfully test a 2,4 GHz AP setup. No way to get 5GHz. While debugging HOSTAPD it seems it is looking for a regulatory domain 00 that got all the 5GHz frequencies no-ir (no-initiating-radiation-> not usable from hostpad). Usually you change the reg dom to what you need and hostpad will get the working frequencies (I have already been able to do such a thing with a raspi from gui). No way to accomplish: - setting kernel option does not work (modprobe cfg80211 ieee80211_regdom=XX or by conf file) - iw reg set XX does not work (for phy0 self managed). - crda has been deprecated and removed from Debian, I would not install it. I understand there was a LAR option not anymore accessible (would need an older kernel/driver?), that would have made the trick if set to =disabled. It has been removed from configurable paramenters for the **iwlwifi** driver. I cannot understand how to solve the problem and why it should be such complicated. I do not know if that is clear, please help me... regards ed
