How to set wireless access point? (Jessie)

There are two different hostap daemons. One is default and the other one is for some Realtek wifi cards. Both have their own basic configurations and both are patched to gain maximum performances.

Sources: https://github.com/igorpecovnik/hostapd

Default binary and configuration location:

/usr/sbin/hostapd
/etc/hostapd.conf

To start AP automatically:

  1. Edit /etc/init.d/hostapd and add/alter location of your conf file DAEMON_CONF=/etc/hostapd.conf and binary DAEMON_SBIN=/usr/sbin/hostapd

  2. Copy /etc/network/interfaces.hostapd to /etc/network/interfaces

  3. Reboot

  4. Predefined network name: “SSID” password: 12345678

  5. To change parameters, edit /etc/hostapd.conf BTW: You can get WPAPSK the long blob from wpa_passphrase YOURNAME YOURPASS
