+without rfkill hostapd does not start and prints this error:

+  Feb 12 09:56:39 bpi-r3 hostapd[2764]: wlan1: IEEE 802.11 Hardware does not support configured channel
+and iw shows "(no IR)" after all channels
+ubuntu does not have the crda tool and so cfg80211 needs the regulatory.db
+it can be installed with wireless-regdb or copy  regulatory.db and regulatory.db.p7s from https://mirrors.edge.kernel.org/pub/software/network/wireless-regdb/
+to load the file cfg80211 needs to be compiled as module and it needs the CONFIG_CFG80211_WEXT option (else you get the error "nl80211 not found" error when using iw).
