It is probably telling you that you have not configured rfkill in your kernel?

$ grep RFKILL /usr/src/linux/.config
CONFIG_RFKILL=m
CONFIG_RFKILL_LEDS=y
CONFIG_RFKILL_INPUT=y
# CONFIG_AMILO_RFKILL is not set
# CONFIG_TOSHIBA_BT_RFKILL is not set


This allows you to control the state of the hardware using any buttons for it 
on your laptop, or by running the command 'rfkill list/block/unblock DEVICE'.

For hostapd use this:

https://wiki.gentoo.org/wiki/Hostapd#802.11a.2Fn.2Fac_with_WPA2-PSK_and_CCMP


For the client look at this:
