hostapd_cli will not connect

[Michael Baird]

To get hostapd_cli to connect, in the hostapd.conf you need to specify 
the option 'ctrl_interface=<path to hostapd socket>'.

from hostapd/hostapd.conf

# Interface for separate control program. If this is specified, hostapd
# will create this directory and a UNIX domain socket for listening to requests
# from external programs (CLI/GUI, etc.) for status information and
# configuration. The socket file will be named based on the interface name, so
# multiple hostapd processes/interfaces can be run at the same time if more
# than one interface is used.
# /var/run/hostapd is the recommended directory for sockets and by default,
# hostapd_cli will use it when trying to connect with hostapd.
ctrl_interface=/var/run/hostapd



I don't follow the rest of your problem.
