Depends on the wifi chipset. Some are deliberately disabled by
their manufacturer from acting in "infrastructure mode", which
is to say, as an access point.

Here's how to tell:

sudo iwconfig wlan1 mode master

will put it into infrastructure mode if it can *and you have an
older chip*


sudo iw list

will show "AP" as an available mode on newer chips.

brctl and hostapd are the right way to go. RF-kill
is sometimes in hardware (physical switch) and sometimes in
software (package rfkill is available starting in Wheezy).
